Best Exhaust For 5 3 Sierra: Compare 10 Cat-Back Kits
A strong exhaust for a 5.3L Sierra should match the truck’s body generation, cab and bed configuration, and preferred exit style before you weigh sound or material. Flowmaster 717857 is a compelling choice for a 2014–2019 Classic-body 1500 because it specifies 5.3L fitment, stainless construction, factory-hanger installation, and a deep tone. This roundup includes kits for older and newer Sierra generations too, but their stated fitments are not interchangeable.
Some listings cover only particular cab and bed combinations, while others specify a single or dual exit. Check your truck’s exact model year and configuration against the product listing before ordering.
The picks below distinguish those fitment windows and highlight the practical differences in tubing, muffler design, and included installation details.
Flowmaster 717857 is the Best Exhaust For 5 3 Sierra among these picks when your truck is a 2014–2019 Classic-body Sierra 1500 with the 5.3L engine. It pairs stated vehicle fitment with full stainless-steel construction, a FlowFX straight-through muffler, factory-hanger compatibility, and a deep tone. Its stated fitment is not universal, so check whether your truck is the Classic body style before choosing it.
For other generations or cab and bed configurations, select a kit whose listed application matches your truck.

#1 · Best Overall
1. Flowmaster 717857 FlowFX
- Compatible with Vehicle Type: Truck
- Material Type: Plastic
- Weight: 47.4 lb
Best for: Stainless setup for classic-body trucks.
Why it ranks #1: Specifically lists 2014–2019 Classic-body Sierra 1500 5.3L fitment, stainless construction, factory-hanger use, and a deep FlowFX tone.
Full stainless-steel construction paired with a FlowFX straight-through muffler gives this cat-back a deep, powerful tone inside and outside the truck. Its listed fitment covers 2014–2019 Classic-body Silverado and Sierra 1500 models with 5.3L engines, and the large black ceramic-coated tip makes the exit visually distinctive.
The 3-inch system’s full stainless construction provides a material choice for buyers prioritizing corrosion resistance, while the straight-through FlowFX muffler shapes its deep, powerful sound. Factory hanger locations support a more direct installation path, and the listing specifies bolt-on installation. A 4.5-inch black ceramic-coated stainless tip completes the exhaust exit. The fitment covers specified Classic-body 4.3L and 5.3L trucks, so buyers should distinguish this application from newer-body models before choosing it.
- Full stainless-steel construction
- FlowFX straight-through performance muffler
- Uses factory hanger locations
- 4.5-inch black ceramic-coated stainless tip
- Fitment is limited to the listed 2014–2019 Classic-body application.

#3 · Older-Generation Dual
3. Flowmaster 17395 American Thunder
- Compatible with Vehicle Type: Car
- Material Type: Plastic
- Weight: 4 lb
Best for: Classic-truck dual-exit upgrade.
Why it ranks #3: Fits 1999–2007 Classic 5.3L Extended Cab Short Bed trucks and includes hangers, hardware, and dual polished stainless tips.
Factory-hanger installation and a Super 40 Series muffler define this Flowmaster cat-back for 1999–2007 Classic Silverado and Sierra 1500 5.3L Extended Cab Short Bed trucks. The hanger locations and included hardware help streamline installation, while its moderate-to-aggressive exterior tone makes the sound change a central part of the upgrade.
Mandrel-bent 16-gauge aluminized steel tubing and a 3-inch system give buyers a defined cat-back configuration for the listed 4.8L and 5.3L applications. Using factory hanger locations, with hangers and hardware included, helps keep the installation workflow tied to existing mounting points. The Super 40 Series muffler is paired with a moderate-to-aggressive exterior tone, while dual 3-inch polished stainless tips finish the same-side exit. Its listed fitment is specific to Classic-body Extended Cab Short Bed trucks.
- Uses factory hanger locations and includes hangers and hardware
- Mandrel-bent 16-gauge aluminized steel tubing
- Super 40 Series performance muffler
- Dual 3-inch polished stainless tips
- The listed fitment is limited to 1999–2007 Classic Extended Cab Short Bed trucks.

Choose this for a 1999–2007 Classic Silverado or Sierra 1500 5.3L Extended Cab Short Bed owner seeking dual same-side exits and a pronounced exterior tone. Its listed cab, bed, and model-year boundaries matter.

#4 · Single-Exit Pick
4. Flowmaster 717976 FlowFX Extreme
- Compatible with Vehicle Type: Truck
- Material Type: Plastic
Best for: Single-exit stainless FlowFX upgrade.
Why it ranks #4: Lists 2014–2019 Sierra 1500 5.3L fitment across wheelbases and 2WD or 4WD, with 3-inch stainless tubing and a single dump exit.
A single dump-style exit and 3-inch mandrel-bent stainless tubing define this Flowmaster FlowFX Extreme cat-back for 2014–2019 Silverado and Sierra 1500 5.3L trucks. The FlowFX muffler offers an aggressive-to-moderate sound level, giving buyers a stated range rather than an extreme-only sound description.
The 3-inch, 16-gauge mandrel-bent stainless tubing is specified to maintain exhaust flow, while 409 stainless construction is described as adding durability and long-term corrosion resistance. A FlowFX performance muffler supplies the aggressive-to-moderate sound character, and the dump-style exit establishes a single-exit layout. Included hardware supports at-home installation. The listing covers 2014–2019 4.3L and 5.3L trucks, 2WD and 4WD, and all wheelbases, with maximum dyno gains stated at 11 hp and 15 lb-ft.
- 3-inch 16-gauge mandrel-bent stainless tubing
- 409 stainless-steel construction
- Includes hardware for at-home installation
- Fits listed 2WD/4WD and all wheelbases
- The single dump-style exit is not a dual rear-exit configuration.
Skip it if you want dual exits through factory bezels on a New Body 5.3L; Flowmaster 717894 lists that layout for 2019–2024 trucks.
This suits 2014–2019 Silverado or Sierra 1500 owners seeking a stainless single-exit system across listed wheelbases and drivetrains. Choose it for the dump-style layout, not a dual rear exit.

#5 · Extreme Sound
5. Flowmaster 817916 Outlaw Extreme
- Compatible with Vehicle Type: Truck
- Material Type: Plastic
- Weight: 10 lb
Best for: Extreme-sound dump-exit setup.
Why it ranks #5: Fits 2014–2019 Classic-body Sierra 1500 5.3L applications and uses a stainless construction with an Outlaw muffler and dump-style exit.
Outlaw muffler technology and an extreme sound profile define this Flowmaster cat-back for 2014–2019 Classic-body Silverado and Sierra 1500 4.3L and 5.3L trucks. Its black single dump-style turndown gives the system a distinctly different exit layout from conventional rear-facing exhaust tips.
The race-proven Outlaw muffler technology is explicitly paired with extreme sound, making this the choice for buyers prioritizing a forceful exhaust note. Stainless-steel construction supplies the stated system material, while the single dump-style turndown determines where and how the exhaust exits. The listing specifies 3-inch tubing and fitment for Classic-body 2014–2019 4.3L and 5.3L trucks. That body-style and year scope is important; the product details do not present it as a universal Sierra 1500 kit.
- Race-proven Outlaw muffler technology
- Extreme sound profile
- Stainless-steel construction
- Single dump-style turndown exit
- The extreme sound profile may not suit buyers seeking a quieter exhaust.
Skip it if you want a deep but powerful FlowFX tone with factory hanger locations; Flowmaster 717857 lists those features for Classic-body trucks.
Pick this for a 2014–2019 Classic-body 5.3L owner who specifically wants Outlaw sound and a single dump exit. Its aggressive sound and defined model-year application are the key boundaries.

#6
6. DNA Motoring Cat-Back
- Compatible with Vehicle Type: Car
Best for: Stainless short-bed cab application.
Why it ranks #6: Covers 2007–2013 Sierra 1500 Crew or Extended Cab Short Bed and specifies T-409 stainless steel with mandrel-bent tubing.
T-409 stainless steel with computerized mandrel bends sets this DNA MOTORING cat-back apart for 2007–2013 Silverado and Sierra 1500 Crew or Extended Cab Short Bed trucks. The listing also specifies TIG-welded CNC-machine flanges, connecting its material and fabrication details to a durability-focused upgrade.
T-409 stainless tubing and computerized mandrel bends are presented as strength- and durability-oriented construction, while TIG-welded CNC-machine flanges are specified for resistance to pressure and corrosion. The kit includes hardware and gaskets, supporting a more complete installation workflow. Its listed fitment is limited to 2007–2013 Crew or Extended Cab Short Bed Silverado and Sierra 1500 models. The listing claims dyno-proven horsepower and low-end torque gains; buyers should weigh those claims alongside the precise cab-and-bed application.
- T-409 stainless-steel construction
- Computerized mandrel bends
- TIG-welded CNC-machine flange
- Hardware and gaskets included
- Fitment is limited to 2007–2013 Crew/Extended Cab Short Bed trucks.
Skip it if you need a dual rear-exit kit for 2007–2014 trucks; Truck Exhaust Kits ShopLine Dual 3-inch lists that broader year range.
This fits buyers targeting the listed 2007–2013 cab-and-bed configuration who value stainless construction, mandrel bends, and included gaskets and hardware. Its narrow fitment means other body, cab, or bed setups fall outside the listing.

#7
7. Auto Dynasty Cat-Back
- Compatible with Vehicle Type: Compatible with Silverado Sierra 1500 2007-2013
- Material Type: Stainless Steel
Best for: Crew-cab short-bed performance system.
Why it ranks #7: Lists 2007–2013 Sierra 1500 Crew or Extended Cab Short Bed compatibility, stainless material, and 3-inch inlet with 4-inch outlet.
A 3-inch inlet feeding a 4-inch outlet defines this stainless-steel cat-back for 2007–2013 Silverado and Sierra 1500 Crew or Extended Cab Short Bed trucks. Its racing-style exit and aggressive tone target buyers who want a more assertive exhaust character within that specific cab-and-bed fitment.
Stainless-steel construction provides the system’s stated material, while the 3-inch inlet and 4-inch outlet establish the pipe dimensions for the exhaust path. The listing describes a racing-design cat-back and claims increased horsepower or low-end torque, but does not supply installation hardware or hanger details here. Fitment is limited to 2007–2013 Crew and Extended Cab Short Bed applications. It is explicitly not CARB compliant and is not legal for use in California emission models, a consequential restriction for some owners.
- Stainless-steel construction
- 3-inch inlet connection
- 4-inch outlet connection
- Listed for 2007–2013 Crew/Extended Cab Short Bed trucks
- Not CARB compliant and not legal for use in California emission models.
Skip it if you need a California-legal system; Flowmaster 717894 lists 2019–2024 New Body trucks and factory-bezel exits.
This is aimed at owners of the listed 2007–2013 Silverado or Sierra 1500 cab-and-bed configurations seeking a racing-style cat-back. Its California emissions restriction is a decisive boundary, not a minor detail.

8. Truck Exhaust Kits ShopLine Dual
- Compatible with Vehicle Type: Truck
- Material Type: Alloy Steel
- Weight: 55 lb
Best for: Dual-exit kit for 2007–2014 trucks.
Why it ranks #8: Offers a dual 3-inch mandrel-bent muffler-back kit for 2007–2014 Sierra 1500 applications, but detailed 5.3L cab fitment is not stated.
Standard dual rear exit and mandrel-bent 3-inch tubing make this ShopLine muffler-back kit a clear option for listed 2007–2014 Silverado and Sierra 1500 applications. Its flow-focused pipe design is intended to reduce restrictions, while the muffler-back layout keeps the scope of the conversion clear.
The dual 3-inch muffler-back arrangement establishes both pipe size and exit style, helping buyers plan around a dual-rear-exit configuration. Mandrel-bent tubing is specified to provide fewer restrictions, and the kit is described as a cat-back system. The listing says these tailpipes fit only the named truck-year ranges and warns that dual-inlet trucks are excluded unless specified. If the truck does not already have a 3-inch muffler inlet pipe, an adapter must be sourced separately.
- Muffler-back dual 3-inch exhaust kit
- Mandrel-bent tubing for fewer restrictions
- Dual rear exit is standard
- Listed for 2007–2014 Silverado/Sierra 1500
- A separate adapter is needed if the truck lacks a 3-inch muffler inlet pipe.
Skip it if you want a stainless kit for 2007–2013 short-bed crew or extended cabs; DNA MOTORING CBE-CS09-4853L-4DR lists that fitment.
Choose this for a listed 2007–2014 Silverado or Sierra 1500 owner who wants dual rear exit and 3-inch mandrel-bent tubing. Verify the inlet and dual-inlet conditions, since an adapter may be required.

9. Truck Exhaust Kits ShopLine Dual
- Compatible with Vehicle Type: Truck
- Weight: 55 lb
Best for: Earlier-truck dual rear exit.
Why it ranks #9: Provides a dual 3-inch mandrel-bent kit for 1999–2006 Silverado and Sierra 1500 trucks, though engine and cab details are limited.
A dual 3-inch muffler-back layout with mandrel-bent tubing gives this ShopLine kit a defined route to a dual rear exit on listed 1999–2006 Silverado and Sierra 1500 trucks. The configuration emphasizes flow and fewer restrictions while keeping the system’s scope to the muffler-back section.
The 3-inch mandrel-bent pipes are specified for maximum flow and fewer restrictions, giving buyers a clear performance-oriented alternative to a standard muffler-back setup. Dual rear exit is the kit’s standard configuration, so the tailpipe layout is established rather than left open-ended. The listing is specific to the earlier Silverado/Sierra 1500 range and notes that dual-inlet trucks are excluded unless specified. A 3-inch muffler inlet pipe is also required; otherwise an adapter must be sourced separately.
- Muffler-back dual 3-inch exhaust kit
- Mandrel-bent tubing
- Dual rear exit is standard
- Listing identifies a specific truck-year application
- A separate adapter is needed if the truck lacks a 3-inch muffler inlet pipe.
Skip it if you need a supplied adapter for a smaller inlet; Flowmaster 17395 includes hangers and hardware for its listed application.
Consider it for a 1999–2006 Silverado or Sierra 1500 owner wanting a dual rear exit and mandrel-bent 3-inch muffler-back tubing. Check the inlet requirement and dual-inlet restriction before committing.

10. XsvFLO ShopLine Single
- Compatible with Vehicle Type: Truck
- Material Type: Aluminum
Best for: Single-exhaust conversion for pickups.
Why it ranks #10: Describes a general late-model gas pickup single system without specific Sierra 5.3L year or cab fitment, making application confirmation essential.
A mandrel-bent 3-inch tailpipe and performance muffler convert a factory single exhaust into a higher-flowing single system. This ShopLine kit can be installed with basic hand tools, making its single-pipe configuration and straightforward tool requirement central considerations for pickup owners planning an exhaust change.
The listed conversion replaces a factory single exhaust with a higher-flowing single setup, rather than adding a dual exit. A mandrel-bent 3-inch tailpipe and performance muffler define the system and are presented as reducing restrictions. The listing says it suits gas applications, all wheelbases, and six- or eight-cylinder pickups, and notes installation with basic hand tools. It does not identify a specific Silverado/Sierra year range in the supplied details, so buyers should not infer a precise 5.3L fit from the general application alone.
- Converts factory single exhaust to a higher-flowing single system
- Mandrel-bent 3-inch tailpipe
- Performance muffler included in the described system
- Can be installed with basic hand tools
- The supplied listing does not specify Silverado/Sierra model years.
Skip it if you need an explicitly listed 2014–2019 Silverado/Sierra 5.3L fit; Flowmaster 717976 names that application.
This suits a pickup owner seeking a single-system conversion, 3-inch mandrel-bent tailpipe, and basic-hand-tool installation. The supplied details do not name Silverado/Sierra years, so a specific 5.3L application is not established.

View on AmazonCheck Sierra body generation before ordering
The main compatibility trap is assuming that similar model-year labels mean the same Sierra body and exhaust layout. The Flowmaster 717857 and Flowmaster 817916 both target 2014–2019 Classic-body trucks, while the Flowmaster 717894 is listed for 2019–2024 new-body trucks. A listing that includes 2019 does not make those systems interchangeable: the body style and specified cab configuration still matter.
Older products also have narrower fitment descriptions. For example, Flowmaster 17395 is for 1999–2007 Classic Extended Cab Short Bed trucks, and DNA Motoring Cat-Back lists 2007–2013 Crew or Extended Cab Short Bed.
Confirm the truck’s body generation, cab, bed, engine, and drivetrain against the maker’s fitment details. If a listing omits one of those details, verify it with the seller or manufacturer rather than inferring compatibility from the engine size alone.
Plan around inlet size and exhaust routing
A larger pipe or alternate exit is useful only if it matches the truck’s existing layout and the space available underneath. The Truck Exhaust Kits ShopLine Dual listing notes that an adapter may be needed if the truck does not already have a 3-inch muffler inlet pipe, and it warns that the kit does not fit dual-inlet trucks unless specified. That is a concrete reason to inspect the existing inlet before choosing a muffler-back kit.
Exit routing also varies: the Flowmaster 717894 exits through factory exhaust bezels, while the Flowmaster 717976 uses a single dump-style exit and the Flowmaster 17395 has dual same-side exits. These are meaningful layout differences, not merely appearance choices.
Compare the listed exit arrangement with your bumper, existing pipe configuration, and intended use; do not assume a dual-exit kit will fit a single-inlet truck without checking.
How to Choose a 5.3L Sierra Exhaust
Model year, body, and cab fitment
Start by matching the complete vehicle application, not just the 5.3L engine. The listings span 1999–2007 Classic, 2007–2013, 2014–2019 Classic, and 2019–2024 new-body applications. Some narrow fitment further: Flowmaster 17395 specifies Extended Cab Short Bed, while Flowmaster 717894 specifies new-body Crew Cab or Double Cab.
For a 2014–2019 Classic 5.3L, Flowmaster 717857 is explicitly listed; for a 2019–2024 new-body 5.3L, Flowmaster 717894 is the matching listed option. Buyers with uncommon cab, bed, or body combinations should favor listings that spell out their configuration and verify any missing details before purchase.
Material and tubing construction
Choose construction based on the material and pipe details actually given for the kit. Flowmaster 717857 and Flowmaster 717894 specify stainless steel, and DNA Motoring Cat-Back identifies T-409 stainless with computerized mandrel bends. Flowmaster 17395 instead describes 16-gauge aluminized-steel tubing, while the ShopLine dual listings specify 3-inch mandrel-bent pipes.
Stainless construction is a useful stated distinction among these choices, but the supplied listings do not provide a comparable corrosion-life test. Buyers prioritizing stainless construction can focus on the Flowmaster and DNA options that name it; those considering an aluminized or alloy-steel kit should check the exact material and intended application in its listing.
Sound, exit style, and layout
Pick the sound character and routing that suit your truck, then confirm the system’s physical layout. Flowmaster 17395 is described as moderate to aggressive and uses dual same-side exits; Flowmaster 717857 promises a deep, powerful tone; Flowmaster 817916 uses Outlaw muffler technology for extreme sound. Exit choices include the 717894’s factory-bezel dual exit, the 717976’s single dump-style exit, and the ShopLine dual kits’ standard dual rear exit.
Buyers seeking an aggressive tone have several Flowmaster choices, but the listed sound descriptions are not standardized measurements. Those wanting to retain factory-bezel routing should consider the specifically stated 717894 layout, while buyers choosing a dump or rear exit should verify clearance and compatibility for their exact truck.
Which 5.3L Sierra exhaust should you choose?
For a 2014–2019 Classic-body Sierra 1500 5.3L, choose Flowmaster 717857 FlowFX for stainless construction, factory-hanger use, and a deep tone. If you have a 2019–2024 new-body Crew Cab or Double Cab, Flowmaster 717894 FlowFX is the generation-specific dual-exit option. Owners of a 1999–2007 Classic Extended Cab Short Bed can consider Flowmaster 17395 American Thunder for its stated fitment and included hardware.
For a 2014–2019 Classic truck where a single dump exit suits the layout, Flowmaster 717976 FlowFX Extreme lists 2WD and 4WD fitment across wheelbases. If your Sierra falls outside these exact descriptions, confirm cab, bed, body, and inlet configuration with the manufacturer before ordering; engine size alone is not enough to establish fit.
Frequently Asked Questions
How can I tell whether my Sierra is a Classic-body or new-body truck?
Check the truck’s model year and body style against the exhaust kit’s stated application, then verify the cab and bed configuration. The listings distinguish 2014–2019 Classic-body trucks from 2019–2024 new-body trucks. If the classification is uncertain, confirm it using your vehicle details with the manufacturer before ordering.
Will a cat-back exhaust change my Sierra’s emissions compliance or inspection status?
It depends on the kit and the rules where the truck is registered. The product descriptions here do not establish emissions approval or inspection outcomes. Before buying or installing a system, check local requirements and confirm with the manufacturer that the specific kit is suitable for your vehicle and intended use.
How loud will a performance exhaust sound inside the cab while cruising?
The supplied product information does not quantify cabin sound while cruising, so it cannot establish how loud a particular system will be inside. The editorial verdict describes the Flowmaster 717857’s tone as deep, but that alone does not predict cruising noise. Seek application-specific sound information before choosing.
What details should I match before ordering an exhaust kit?
Match the listed year range, body style, cab and bed configuration, engine, and exhaust layout to your Sierra. The editorial guidance notes that engine size alone is not enough to establish fit. If your truck does not match a stated application exactly, confirm its details with the manufacturer first.
How do the listed exhaust materials and exit styles differ?
The titles identify different materials and layouts: some list aluminized steel, while others specify 409 stainless steel; exit descriptions include dual exhaust, single exit, and single dump. These details do not establish overall performance or durability, so use them to narrow choices only after confirming vehicle fitment.
Final Words
Start with exact fitment, not engine size alone. For a 2014–2019 Classic-body Sierra 1500 with the 5.3L, the Flowmaster 717857 is the stated pick for stainless construction, factory-hanger compatibility, and a deep tone. New-body Crew Cab or Double Cab owners should consider the 717894; other trucks should match cab, bed, body, and inlet details to a listed application or confirm fit with the manufacturer.
