Best Cat Back Exhaust System for Cars and Trucks

Best Cat Back Exhaust System

A strong cat-back exhaust choice matches your exact vehicle and cab or bed configuration, then delivers the sound, construction, and exit style you want. This roundup covers systems for trucks, a Tacoma, a Lexus, and a Honda Civic, so fitment matters more than a feature that sounds impressive in isolation. Options range from T-304 stainless steel and a no-drone guarantee on the Borla to 409 stainless steel systems designed for factory hangers and no-weld installation.

Several listings name specific engines and body styles; others provide less complete application detail. Confirm your vehicle’s year, engine, drivetrain, cab, bed, and trim against the seller’s fitment information before ordering, and check local emissions rules where applicable.

Borla 140753BC is the Best Cat Back Exhaust System pick for buyers with a compatible Ram 1500 V8. Its listing specifies the application, T-304 stainless steel, ATAK muffler, dual split rear exit, black chrome tips, and a no-drone guarantee. It is not a universal choice: the listed fit excludes Ram Classic and calls out a particular cab, bed, and wheelbase configuration.

Verify those details against your truck before buying.

Detailed Reviews: Best Cat Back Exhaust System

Borla 140753BC

#1 · Best Overall

1. Borla 140753BC

Best for: Ram owners seeking ATAK sound.

Why it ranks #1: The Ram V8 listing specifies T-304 stainless steel, ATAK sound, dual split rear exit, and a no-drone guarantee, with clear Classic exclusion.

Borla’s ATAK muffler and dual split rear exit define this cat-back’s appeal for compatible Ram 1500 V8 owners seeking a specific sound and outlet layout. Its T-304 stainless-steel construction and bolt-on installation add concrete material and installation details, while the listing explicitly excludes Ram Classic models.

The application is a 2019–2023 Ram 1500 V8, including E-Torque but excluding Classic, with further listed details specifying a 5.7L Crew Cab and short bed. That makes checking the exact truck configuration essential before purchase. The ATAK muffler supplies the named sound character, while the dual split rear exit and single 5-inch round black chrome tips on each side establish the visible outlet arrangement. T-304 stainless steel, all-welded construction, and bolt-on installation provide material and installation context; Borla also states a no-drone guarantee.

Pros
  • T-304 stainless-steel construction
  • ATAK muffler
  • Dual split rear exit with 5-inch tips on each side
  • Bolt-on installation and all-welded construction
Cons
  • Does not fit Ram Classic models.

Skip it if you drive a Ram Classic; this system explicitly excludes it, regardless of the other listed Ram 1500 fitment details.

This targets owners of the specified 2019–2023 Ram 1500 V8 who want an ATAK muffler, split rear exits, and bolt-on installation. The major boundary is fitment: Ram Classic models are excluded.

Rough Country F-150 96010

#2 · Easy Home Install

2. Rough Country F-150 96010

  • Material: Stainless Steel
  • Material Type: Stainless Steel
  • Compatible with Vehicle Type: 2009-2014 2WD Ford F-1502009-2014 4WD

Best for: F-150 DIY dual-exit shoppers.

Why it ranks #2: This F-150 system fits listed 2WD and 4WD applications, installs into OEM hangers without welding, and includes dual black tips.

Installation into OEM hangers without welding is the practical draw of Rough Country’s dual cat-back for 2009–2014 F-150 2WD and 4WD models. Its dual design allows side or rear exits, giving buyers an outlet-layout choice alongside corrosion-resistant 409 stainless tubing and black dual-wall tips.

Rough Country lists compatibility with 2009–2014 Ford F-150 2WD and 4WD models, and the dual cat-back design offers side or rear exits. That layout choice helps buyers select an exhaust route suited to their intended appearance. The system uses 409 stainless steel with 16-gauge tubing, plus dual-wall 304 stainless black tips, specifying different materials for tubing and tips. It installs into OEM hangers without welding, a useful feature for a home installation workflow; the listing also describes a throaty sound and airflow tuning.

Pros
  • Dual design offers side or rear exits
  • 409 stainless steel with 16-gauge tubing
  • Dual-wall 304 stainless-steel black tips
  • Installs into OEM hangers without welding
Cons
  • Fitment is limited to 2009–2014 Ford F-150 models.

Skip it if you want a rear-exit system for a 2019–2024 Chevy or GMC; Rough Country 96011 lists that newer truck application.

This suits 2009–2014 F-150 owners seeking dual exits and a no-welding installation into OEM hangers. The listed application covers both 2WD and 4WD, but it does not extend to other model years or truck makes.

Rough Country Sierra 96011

#3 · Factory Tip Option

3. Rough Country Sierra 96011

  • Material: Stainless Steel
  • Material Type: Stainless Steel
  • Compatible with Vehicle Type: 2019-2024 4WD Chevy Silverado

Best for: Newer Chevy/GMC rear-exit buyers.

Why it ranks #3: The 5.3L Chevy/GMC listing offers rear exit, OEM hanger installation without welding, and the option to retain OEM dual tips.

Rear exit with the option to retain OEM dual tips sets this Rough Country system apart for listed newer Chevy and GMC truck applications. Its 409 stainless-steel tubing and no-welding installation into OEM hangers give buyers clear construction and installation details, while the design is specified as dual cat-back.

The listing names a 2019–2024 Chevy/GMC Sierra application and separately specifies 2019–2024 4WD Chevy Silverado compatibility, so buyers should use the stated vehicle information when checking applicability. The dual design exits at the rear and can retain OEM dual tips, supporting a factory-tip look where applicable. Corrosion-resistant 409 stainless steel, 16-gauge tubing, and a 409 stainless black muffler and clamps describe the system’s construction. Installation uses OEM hangers without welding, simplifying the stated installation workflow.

Pros
  • Dual cat-back rear-exit design
  • Can retain OEM dual tips
  • Corrosion-resistant 409 stainless steel with 16-gauge tubing
  • Installs into OEM hangers without welding
Cons
  • The specifications list Silverado compatibility for 4WD models only.

Skip it if you need a listed 2WD Silverado application; the supplied compatibility specifies 4WD Silverado, while Rough Country 96010 lists F-150 2WD and 4WD.

This suits buyers considering the listed newer Chevy/GMC truck application who want rear exits, OEM hanger installation, and the option to retain OEM dual tips. Note the supplied Silverado compatibility is specifically listed as 4WD.

DNA MOTORING Civic CBE-HC922-NRT

#4 · T-304 Civic Fit

4. DNA MOTORING Civic CBE-HC922-NRT

Best for: Older Civic coupe and sedan owners.

Why it ranks #4: For 1992–2000 Civic coupes and sedans, it lists T-304 stainless steel, mandrel bends, and TIG-welded CNC-machined flanges.

T-304 stainless steel and computerized mandrel bends give this DNA MOTORING cat-back a specifically described construction for 1992–2000 Honda Civic coupes and sedans. The listed fitment targets older Civic owners, while the stated deep, smooth tone and performance claim identify the intended exhaust character and output focus.

The application is listed for 1992–2000 Honda Civic Coupe and Sedan models, giving owners a focused fitment range. T-304 stainless steel and computerized mandrel bends specify the tubing construction, while TIG-welded CNC-machined flanges are described as resisting pressure and corrosion. DNA MOTORING states a dyno-proven 15–25 horsepower or low-end torque increase and describes an aggressive, deep, smooth tone with exhaust gas flow. Hardware and gaskets are included as shown, which helps define what the supplied package contains.

Pros
  • Listed fitment covers 1992–2000 Honda Civic Coupe and Sedan
  • T-304 stainless-steel construction
  • Computerized mandrel bends
  • Listing states a dyno-proven 15–25 horsepower or low-end torque increase
Cons
  • The stated fitment covers only 1992–2000 Civic coupes and sedans.

Skip it if you own a later Civic or a truck; this system’s stated application is limited to 1992–2000 Civic coupes and sedans.

This is for owners of a 1992–2000 Honda Civic coupe or sedan seeking the listed stainless construction and deep, smooth tone. Its stated vehicle range is specific, so other Civic generations are outside the supplied fitment.

DNA MOTORING Silverado CBE-CS09

#5

5. DNA MOTORING Silverado CBE-CS09

  • Compatible with Vehicle Type: Car

Best for: Stainless truck upgrade shoppers.

Why it ranks #5: The Silverado/Sierra short-bed application is specified, with T-409 stainless steel, mandrel bends, TIG-welded flanges, and hardware and gaskets listed.

T-409 stainless steel with computerized mandrel bends distinguishes this DNA MOTORING kit, pairing a named tubing material with shaped exhaust piping for specified Silverado and Sierra trucks. The listed fitment covers 2007–2013 Crew or Extended Cab Short Bed models, making configuration a central part of the buying decision.

The fitment listing covers 2007–2013 Chevy Silverado 1500 and GMC Sierra 1500 Crew or Extended Cab Short Bed trucks, while T-409 stainless steel and computerized mandrel bends specify the system’s construction. TIG-welded CNC-machined flanges are described as resisting pressure and corrosion, a practical consideration for buyers focused on durable connections. DNA MOTORING also lists a dyno-proven 15–25 horsepower or low-end torque increase and an aggressive, deep sound; hardware and gaskets are included as shown.

Pros
  • T-409 stainless-steel construction
  • Computerized mandrel bends
  • TIG-welded CNC-machined flanges
  • Listing states a dyno-proven 15–25 horsepower or low-end torque increase
Cons
  • Fitment is limited to specified 2007–2013 Silverado and Sierra short-bed cab configurations.

Skip it if you own a 2019–2024 Chevy or GMC truck and want rear-exit dual pipes; Rough Country’s 96011 lists that newer application.

This fits buyers with the stated 2007–2013 Silverado or Sierra 1500 cab and short-bed configuration who value specified stainless construction and the listed performance claim. Its vehicle application is narrow, so other truck years fall outside the supplied fitment.

Auto Dynasty Silverado 1500

#6

6. Auto Dynasty Silverado 1500

  • Material: Stainless Steel
  • Material Type: Stainless Steel
  • Compatible with Vehicle Type: Compatible with Silverado Sierra 1500 2007-2013

Best for: Silverado and Sierra short-bed owners.

Why it ranks #6: It specifies Silverado/Sierra crew or extended cab short-bed fitment, stainless steel, and 3-inch inlet and 4-inch outlet connections.

A 3-inch inlet paired with a 4-inch outlet gives the Auto Dynasty system a clearly specified pipe connection setup for compatible Silverado and Sierra 1500 trucks. Its listed Crew or Extended Cab, Short Bed fitment focuses the kit on a defined truck configuration, while its racing-style exit targets buyers wanting an aggressive exhaust tone.

The listing specifies compatibility with 2007–2013 Chevy Silverado 1500 and GMC Sierra 1500 Crew or Extended Cab Short Bed models, helping buyers assess whether this truck-focused kit matches their configuration. Stainless steel construction accompanies the 3-inch inlet and 4-inch outlet dimensions, providing concrete material and connection details for installation planning. Auto Dynasty describes the system as supporting exhaust flow and an aggressive tone, and its non-CARB-compliant status is an important use restriction, especially for California emission models.

Pros
  • Listed fitment covers 2007–2013 Silverado and Sierra 1500 Crew/Extended Cab Short Bed
  • Stainless-steel construction
  • 3-inch inlet connection
  • 4-inch outlet connection
Cons
  • Not legal for use on California emission models.

Skip it if you need a CARB-compliant exhaust for a California emission model; this listing explicitly excludes that use.

This is for Silverado or Sierra 1500 owners with the specified 2007–2013 cab and short-bed configuration who want the listed large outlet and aggressive tone. California emission-model restrictions are a firm boundary.

#7

7. Flowmaster American Thunder 17395

  • Material: Plastic
  • Material Type: Plastic
  • Compatible with Vehicle Type: Car

Best for: Classic Silverado short-bed owners.

Why it ranks #7: The listing targets classic Silverado/Sierra 1500 4.8L and 5.3L extended-cab short beds, with hangers, hardware, and stainless tips.

A Super 40 Series muffler and dual same-side exit define the Flowmaster American Thunder kit for specified Classic Silverado and Sierra trucks. Its 3-inch mandrel-bent tubing and polished stainless tips combine a stated pipe size with a distinct outlet arrangement, while factory-hanger use informs installation planning.

The stated application covers 1999–2007 Classic Chevy Silverado and GMC Sierra 1500 4.8L or 5.3L Extended Cab Short Bed models, making vehicle configuration central to fitment. Mandrel-bent 16-gauge aluminized-steel tubing and a Super 40 Series muffler provide named construction and exhaust components. The kit includes hangers and hardware and uses factory hanger locations, supporting an installation plan based on existing mounting points. Flowmaster describes the exterior tone as moderate to aggressive and includes dual 3-inch polished stainless tips in a same-side exit arrangement.

Pros
  • Listed for specified 1999–2007 Classic Silverado and Sierra 1500 models
  • Mandrel-bent 16-gauge aluminized-steel tubing
  • Super 40 Series performance muffler
  • Includes hangers and hardware and uses factory hanger locations
Cons
  • Tubing is aluminized steel rather than stainless steel.

Skip it if you want an all-stainless system with rear or side exit choices; Flowmaster 817689 lists both exit layouts and stainless construction.

This fits buyers with the specified Classic Silverado or Sierra 1500 Extended Cab Short Bed and 4.8L or 5.3L engine seeking a same-side dual exit. Its tubing is aluminized steel, not stainless.

PHILTOP Tacoma Cat-Back

#8

8. PHILTOP Tacoma Cat-Back

  • Material: Stainless Steel
  • Material Type: Stainless Steel

Best for: Tacoma 4.0L V6 owners.

Why it ranks #8: This Tacoma system lists 4.0L V6 fitment across specified application years, stainless steel construction, and a two-year manufacturer warranty.

Fitment for Toyota Tacoma 4.0L V6 models from 2005–2009 and 2011–2015 is this PHILTOP system’s defining detail, giving owners a clearly delimited cat-back option. The listing identifies stainless-steel construction and describes corrosion resistance, making material longevity a stated part of its appeal for those Tacoma applications.

The system is listed for 2005–2009 and 2011–2015 Toyota Tacoma 4.0L V6 models, so the omitted 2010 model year is a meaningful fitment boundary. Stainless-steel construction and the described corrosion resistance give buyers material information when considering long-term use. The listing also references larger pipes, low-restriction mufflers, and tuned resonators in connection with exhaust flow and noise, although it provides no specific sound level. Included components are listed as one cat-back exhaust, and dimensions are 45.28 by 10.24 by 10.63 inches.

Pros
  • Listed for Tacoma 4.0L V6 models in 2005–2009 and 2011–2015
  • Stainless-steel construction
  • Described as corrosion resistant
  • Listing identifies larger pipes, low-restriction mufflers, and tuned resonators
Cons
  • The listed Tacoma fitment excludes model year 2010.

Skip it if you have a 2010 Tacoma; this product’s stated year ranges omit that model year.

This is aimed at Toyota Tacoma owners with the listed 4.0L V6 model years who want a stainless cat-back and the described flow and noise components. The fitment list excludes 2010, so that year is outside its stated application.

PHILTOP Lexus Cat-Back

#9

9. PHILTOP Lexus Cat-Back

Best for: Lexus IS250/IS350 owners.

Why it ranks #9: The system is listed for Lexus IS250/IS350 applications and describes corrosion-resistant stainless steel, but provides fewer fitment and installation specifics.

Compatibility with 2006–2010 Lexus IS250 and IS350 models is the PHILTOP system’s clearest advantage, giving owners a vehicle-specific cat-back option rather than a general-purpose kit. Its listed stainless-steel construction and exhaust components target buyers seeking a replacement or performance-oriented exhaust for this defined Lexus fitment.

The stated 2006–2010 IS250/IS350 compatibility narrows the choice to owners of those Lexus models, while the stainless-steel construction is identified as corrosion resistant. The listing describes larger pipes, low-restriction mufflers, and tuned resonators as features intended to affect exhaust flow and noise, giving buyers a sense of the system’s approach. Product dimensions are 49.21 by 7.87 by 23.23 inches and weight is 27.7 pounds, useful details when planning handling and storage before installation.

Pros
  • Fits listed 2006–2010 Lexus IS250 and IS350 models
  • Stainless-steel construction
  • Described as corrosion resistant
  • Listing identifies larger pipes, low-restriction mufflers, and tuned resonators
Cons
  • Fitment is limited to the listed Lexus model years and vehicles.

Skip it if you own a Tacoma or truck rather than a listed Lexus IS; PHILTOP’s Tacoma system serves a different vehicle application.

This suits a 2006–2010 Lexus IS250 or IS350 owner seeking a stainless cat-back with listed flow and sound components. Its main boundary is straightforward: the stated fitment does not cover other Lexus years or models.

Flowmaster Outlaw 817689

#10

10. Flowmaster Outlaw 817689

Best for: Aggressive-sound exhaust shoppers.

Why it ranks #10: It offers all-stainless construction, factory hanger locations, and rear or side exit options, but the supplied listing does not identify vehicle fitment.

Flowmaster’s Super 10 performance muffler gives this Outlaw cat-back a named source for its deep, aggressive sound, while dual-out-the-rear or dual-out-the-side choices provide two exit layouts. All-stainless construction and factory-hanger mounting add useful material and installation details for buyers comparing exhaust systems.

This system combines an all-stainless-steel construction with Flowmaster’s Super 10 performance muffler, a pairing relevant to buyers prioritizing material and a deep, aggressive exhaust note. The listing offers dual-out-the-rear or dual-out-the-side exit options, letting the buyer choose between two stated outlet arrangements. Large 4-inch black ceramic-coated tips specify the visible finish and size, while use of factory hanger locations supports a mounting approach based on existing hangers. The listing describes installation as easy, but provides no vehicle fitment details here.

Pros
  • All-stainless-steel construction
  • Super 10 performance muffler
  • Dual rear or dual side exit options
  • 4-inch black ceramic-coated tips
Cons
  • The supplied listing provides no vehicle fitment details.

Skip it if you require a stated vehicle-specific application before choosing; Flowmaster’s 17395 listing names Silverado and Sierra fitment details.

This is for buyers prioritizing a Super 10 muffler, aggressive sound, and a choice of dual exit layout. The supplied details do not identify compatible vehicles, so vehicle-specific applicability remains its key boundary.

Fitment details that can make a system incompatible

A matching make and model name alone does not establish that a cat-back system fits your vehicle. The Borla listing, for example, specifies a Ram 1500 V8 application and excludes Classic models, while its description narrows fitment to a particular cab, short bed, and wheelbase. The Flowmaster American Thunder listing also calls out engine size and extended cab short bed, rather than every Silverado or Sierra.

Before ordering, compare the system’s application with your vehicle’s engine, drivetrain, cab, bed, trim, and existing exhaust layout. Check whether the listing covers your exact configuration, not just the model family.

Conflicting or incomplete fitment information is a reason to verify with the manufacturer or seller before purchase; the product names and general compatibility claims do not resolve every vehicle variation.

Sound and emissions are separate trade-offs

A cat-back system’s sound description does not establish whether it is legal for your vehicle or location. The products here span Borla’s ATAK sound and Flowmaster’s Super 10 and Super 40 muffler descriptions, while Rough Country describes an aggressive, throaty tone. Those labels help distinguish the intended character, but the supplied specifications do not provide comparable sound measurements.

One listing, Auto Dynasty’s Silverado/Sierra system, expressly says it is not CARB compliant and not legal for use in California emission models. That warning makes emissions verification especially important for California buyers; do not assume another system is approved merely because its listing lacks a warning.

Check local rules and the manufacturer’s application information before purchase, particularly if the vehicle is subject to emissions inspection.

How to Choose a Cat-Back Exhaust

Vehicle and configuration fit

Start by matching the exhaust to your exact vehicle configuration, not just its model name. The listings range from the 1992–2000 Honda Civic coupe/sedan and Lexus IS250/IS350 applications to truck systems with engine, cab, bed, and drivetrain limits. Borla identifies a Ram 1500 V8 application and excludes Classic models; Flowmaster’s American Thunder calls out 4.8L and 5.3L extended-cab short-bed trucks.

Rough Country lists F-150 2WD and 4WD fitment, while the Tacoma PHILTOP listing specifies a 4.0L V6. A buyer with an exact matching truck configuration can consider those vehicle-specific kits; anyone with a less common cab, bed, engine, or trim should confirm compatibility before ordering.

Material and construction

Choose construction based on the material actually stated for the system and your intended use. Borla specifies T-304 stainless steel; DNA MOTORING lists T-304 for its Civic system and T-409 stainless steel for its Silverado/Sierra system. Rough Country specifies corrosion-resistant 409 stainless steel tubing, muffler, and clamps, with 304 stainless tips.

Flowmaster American Thunder instead lists 16-gauge aluminized-steel tubing with stainless tips. These are different material descriptions, not a common durability rating, and the supplied information does not establish comparative service life.

Buyers who prioritize a listed stainless-steel system can focus on Borla, DNA MOTORING, PHILTOP, or Rough Country; those considering aluminized tubing should weigh that material distinction against their conditions and maintenance needs.

Exit layout and installation

Check where the exhaust exits and how the kit attaches before choosing a system. Rough Country’s F-150 kit offers side or rear exits and says it installs into OEM hangers without welding; its Sierra system uses a rear exit and can retain OEM dual tips. Borla describes a dual split rear exit, while Flowmaster Outlaw lists rear or side exit options.

Flowmaster American Thunder uses a dual same-side exit and includes hangers and hardware. If a factory-hanger, no-weld installation is your priority, the Rough Country listings spell that out.

Buyers seeking a particular rear, side, or same-side layout should compare that design with the vehicle’s existing configuration and confirm what installation work the specific kit requires.

Which Cat-Back System Fits Your Vehicle?

Choose by exact vehicle fit first. For a compatible Ram 1500 V8 owner seeking a specifically listed ATAK system with T-304 stainless steel and a no-drone guarantee, Borla 140753BC leads. For a 2009–2014 F-150 buyer who wants OEM-hanger installation without welding, Rough Country F-150 96010 is a strong match; the Sierra 96011 suits listed 5.3L Chevy/GMC applications and can retain OEM dual tips.

Honda Civic owners with a 1992–2000 coupe or sedan can consider DNA MOTORING Civic CBE-HC922-NRT. For a classic Silverado/Sierra extended-cab short bed, compare Flowmaster American Thunder 17395 with the Silverado-specific DNA MOTORING or Auto Dynasty systems, checking each application and emissions restrictions.

Tacoma and Lexus owners should verify PHILTOP fitment details before ordering. The Flowmaster Outlaw listing needs fitment confirmation.

Frequently Asked Questions

How do I confirm a cat-back system fits my vehicle’s engine, cab, bed, and drivetrain?

Match the listing to your vehicle’s year, make, model, engine, cab, bed, and drivetrain before ordering. Check exclusions and wheelbase details too; for example, the Borla listing excludes Ram Classic and specifies a particular cab, bed, and wheelbase configuration. If any detail is unclear, confirm fitment with the seller.

Will a louder cat-back exhaust create cabin drone during highway driving?

It can, but the supplied listings do not establish highway drone performance for every system. Check the specific product’s sound description and any stated drone guarantee rather than assuming all cat-back systems behave alike. The Borla listing specifically includes a no-drone guarantee; that claim should not be extended to the other products.

Do cat-back exhaust systems require emissions approval in my state?

Requirements depend on where you register and drive the vehicle, and the supplied product information does not establish approval for every state. Check your state and local emissions rules, then verify the specific system’s approval status with the seller or manufacturer before buying. Do not assume a cat-back listing is automatically compliant.

What installation details should I check before ordering?

Confirm the listing’s installation requirements and included configuration before ordering, and check whether your vehicle’s existing hardware is addressed. Rough Country’s F-150 listing is noted as allowing OEM-hanger installation without welding; do not assume that applies to other systems. If the listing is unclear, ask the seller or installer to verify.

How should I choose between stainless steel and aluminized steel systems?

Compare the material stated in each listing and consider your priorities for the specific application. The Borla and DNA MOTORING listings specify stainless steel, while Flowmaster 17395 specifies aluminized steel. The supplied information does not establish comparative lifespan or performance, so verify material details and other requirements against the product listing.

Final Words

Start with exact vehicle fit, including engine, cab, bed, drivetrain, and any listed exclusions. For a compatible Ram 1500 V8, Borla 140753BC leads if its specified configuration matches your truck and you want its listed ATAK setup and no-drone guarantee. Otherwise, compare the application-specific options, installation details, materials, and emissions requirements.

Confirm uncertain fitment—especially for the Flowmaster Outlaw and PHILTOP systems—before ordering.
