Best Sounding Exhaust For F150 Ecoboost: Compare Cat-Backs

#1 · Best Overall

1. Borla 140616BC

• Material Type: Stainless Steel
• Weight: 58 lb

Best for: Stainless Bolt-On Upgrade.

Why it ranks #1: T-304 stainless steel, all-welded construction, and a stated no-drone guarantee suit buyers seeking a refined EcoBoost cat-back.

T-304 stainless steel construction is the defining feature of Borla’s cat-back system, pairing durable material with bolt-on installation for owners seeking a replacement exhaust without a welding step. Its listed no-drone guarantee also makes cabin comfort part of the system’s stated appeal.

The all-welded construction and bolt-on installation combine a finished system with a mounting approach that avoids a welding requirement. T-304 stainless steel is the specified material, while the no-drone guarantee addresses an important in-cabin consideration for daily driving. The listing identifies 2015–2020 F-150 applications and several engine and cab/bed configurations, but it also excludes the Raptor and specifies particular configurations for some fitments. Check those stated boundaries before selecting it.

Skip it if you need a 2021-or-newer truck; B2 Fabrication’s 2021–2025 system lists newer F-150 applications.

A good match for owners of listed 2015–2020 F-150 configurations who want stainless construction, bolt-on installation, and a stated no-drone guarantee. Its cab, bed, and Raptor fitment boundaries make application selection important.

#2 · Best Sound Range

2. Flowmaster 717785 FlowFX

• Material Type: Plastic
• Compatible with Vehicle Type: Car
• Weight: 42.3 lb

Best for: Moderate-to-Aggressive Sound.

Why it ranks #2: Its FlowFX straight-through muffler is described as moderate/aggressive, and the listing covers 2.7L and 3.5L EcoBoost trucks.

Flowmaster’s straight-through FlowFX muffler is paired with a stated moderate-to-aggressive sound, giving this cat-back a clear auditory identity. Dual 2.5-inch mandrel-bent stainless tubing and factory-hanger mounting make it a specific choice for listed 2015–2020 F-150 applications.

The straight-through FlowFX muffler is described as dyno tuned for maximum performance, while the moderate-to-aggressive sound rating gives buyers a stated tone direction. Dual 2.5-inch mandrel-bent stainless tubing forms the system’s specified pipe layout. Using factory hanger locations supports installation around the truck’s existing mounting points, and the listing calls installation easy. Fitment covers 2015–2020 2.7L, 3.5L, and 5.0L trucks, except standard-cab short-bed configurations.

Skip it if you have a standard-cab short-bed F-150; MBRP’s 2021-onward S5209AL is for newer model years instead.

A fit for owners of listed 2015–2020 F-150 configurations who want dual stainless tubing, factory-hanger installation, and a moderate-to-aggressive tone. Standard-cab short-bed trucks are expressly excluded.

#3 · Most Sound Options

3. B2 Fabrication Dual Outlet

• Compatible with Vehicle Type: Truck

Best for: Adjustable Sound Level Buyers.

Why it ranks #3: Buyers can choose an 18-inch moderate muffler, 14-inch aggressive muffler, or Y-pipe very aggressive setup for listed EcoBoost engines.

Three listed sound configurations—from an 18-inch moderate muffler to a 14-inch aggressive muffler and a very-aggressive Y-pipe—give this B2 Fabrication system a clear sound-choice advantage. It covers 2021–2025 F-150s with 2.7L, 3.5L, or 5.0L engines, excluding Powerboost.

The system bolts to the factory resonator pipe, which gives installation a defined connection point rather than requiring a described custom routing process. CNC mandrel-bent stainless tubing and fixture welding are specified for precise fit, while polished or black Cerakote tips let buyers choose a finish. Select among the moderate, aggressive, and very-aggressive configurations to suit the desired sound character. Its stated vehicle range covers 2021–2025 engines listed, but explicitly leaves out Powerboost.

Skip it if you own a Powerboost; Rough Country’s listed 2021–2024 dual cat-back system covers 2WD and 4WD applications.

Choose it if you own a listed 2021–2025 F-150 and want to select among moderate, aggressive, or very aggressive sound options. Powerboost owners are outside the stated compatibility, so that boundary rules it out.

#4 · Best Side Exit

4. Roush 421985

• Weight: 53.9 lb

Best for: Side-Exit Stainless System.

Why it ranks #4: The side-exit cat-back is listed for 2.7L and 3.5L engines and uses T409 stainless steel with a lifetime warranty.

Roush specifies T409 stainless steel for this side-exit cat-back, giving F-150 owners a concrete material and routing combination. Its listed application covers 2015–2020 2.7L, 3.5L, and 5.0L trucks, while excluding the Raptor.

The side-exit layout defines where the exhaust leaves the truck, a practical consideration for buyers choosing a particular outlet arrangement. T409 stainless steel is the named construction material, and the listing pairs it with long-term durability and easy maintenance claims. Fitment information names 2015–2020 F-150s with 2.7L, 3.5L, or 5.0L engines, excluding Raptor models. The supplied details do not identify a sound level, so sound character cannot be selected from stated options.

Skip it if you drive a Raptor; Borla’s listed 2015–2020 system also excludes Raptor, so neither listed application covers it.

Consider this for a non-Raptor 2015–2020 F-150 owner who wants T409 construction and a side exit. The listing does not provide a sound-level choice, so buyers selecting by stated tone should look elsewhere.

#5 · Best Black Tips

5. Rough Country 96018

• Material Type: Stainless Steel
• Compatible with Vehicle Type: 2021-2023 4WD Ford F-1502021-2023 2WD
• Weight: 68 lb

Best for: At-Home Dual Side-Exit Install.

Why it ranks #5: This dual side-exit kit has 304 black tips and a stainless muffler, with OEM-hanger installation and no welding required.

Rough Country combines a dual side-exit layout with installation into OEM hangers and no welding, giving at-home installers a concrete setup advantage. The system lists corrosion-resistant 409 stainless tubing and black 304 stainless tips for 2021–2024 F-150 2WD and 4WD applications.

Installing into OEM hangers without welding gives owners a defined route to fit the cat-back at home, according to the product details. Its 16-gauge, corrosion-resistant 409 stainless tubing is paired with a 304 stainless muffler, clamps, and dual-wall tips, specifying materials across key components. Dual side exits establish the outlet layout. Listed compatibility covers 2021–2024 2WD and 4WD trucks, though the supplied compatibility specifications specifically name 2021–2023.

Skip it if you require a clearly consistent 2024 fitment statement; B2 Fabrication explicitly lists 2021–2025 applications, excluding Powerboost.

This is a practical pick for a listed 2021–2023 F-150 owner seeking dual side exits and a no-weld, OEM-hanger installation. The title says through 2024, but the compatibility specifications stop at 2023.

#6

6. MBRP S5262AL

• Material Type: Metal
• Compatible with Vehicle Type: Truck
• Weight: 62 lb

Best for: Rugged Dual-Outlet Setup.

Why it ranks #6: A 3-inch mandrel-bent system with pre-axle dual outlets offers a distinct layout, but the listing excludes regular-cab short-box trucks.

A pre-axle dual outlet and mandrel-bent three-inch tubing give this MBRP cat-back a distinctive routing and pipe specification. Its T409 construction is described as rugged against road exposure, making it a candidate for F-150 owners prioritizing durable hardware over a listed sound-level choice.

The 3-inch mandrel-bent tubing provides a defined pipe size, while the pre-axle dual outlet sets the exhaust routing and exit arrangement. MBRP identifies T409 construction and describes the XP Series material as able to withstand salt, rocks, tar, and grime, a useful consideration for trucks exposed to road debris. Installation is listed as bolt-on. Fitment excludes regular-cab short-box trucks, so that specific configuration is outside the stated application.

Skip it if you have a regular-cab short-box truck; Borla’s listed configurations include other cab-and-bed combinations.

This suits F-150 owners seeking a bolt-on, dual-outlet layout with specified three-inch tubing and T409 construction. The regular-cab short-box exclusion is a firm fitment boundary, and no sound level is specified.

#7

7. MBRP S5209AL

• Material Type: Alloy Steel
• Compatible with Vehicle Type: Truck

Best for: Single-Side Outlet Preference.

Why it ranks #7: The listing covers 2.7L and 3.5L F-150 engines and specifies a 4-inch tube, 5-inch tip, and single-side exit.

A four-inch exhaust tube paired with a five-inch tip and single-side exit defines MBRP’s S5209AL cat-back. The listing also states torque and horsepower improvement, lower exhaust-gas temperatures, and increased throttle response for 2021-onward F-150s with 2.7L, 3.5L, or 5.0L engines.

The four-inch tubing and five-inch tip provide specific dimensions for buyers choosing an exhaust by pipe and outlet size. A single-side exit keeps the routing choice clear, while bolt-on installation specifies the mounting approach. MBRP lists improved torque and horsepower, lower exhaust-gas temperatures, and increased throttle response as benefits. Construction is aluminized alloy steel, a material detail buyers should weigh when choosing this system. The application is listed for 2021-onward F-150 engine options.

Skip it if you want stainless construction; Rough Country’s 2021–2024 system lists 409 stainless tubing and 304 stainless tips.

Choose this for a 2021-onward F-150 owner who prefers a single-side outlet and the specified four-inch pipe and five-inch tip. Its aluminized alloy-steel construction is the material boundary to consider.

#8

8. DNA MOTORING CBE-F150-15-27L

• Material Type: Stainless Steel

Best for: Deep-Tone T-304 System.

Why it ranks #8: This T-304 stainless system explicitly fits 2.7L and 3.5L engines in a narrower model range and describes an aggressive, deep tone.

DNA Motoring describes an aggressive, deep, smooth tone alongside T-304 stainless construction, making sound character and material the system’s clearest selling points. Its stated fitment covers 2015–2017 Ford F-150s with 2.7L or 3.5L engines.

Computerized mandrel bends and TIG-welded CNC-machined flanges are specified alongside T-304 stainless steel, connecting the construction details to strength, durability, and pressure and corrosion resistance claims. The listing also describes smooth exhaust-gas flow and a deep, aggressive, smooth tone, giving sound-focused buyers a stated character to consider. Claimed power and torque figures are present in the source, but the system’s fitment is limited to 2015–2017 2.7L and 3.5L F-150s.

Skip it if you need a 2018–2020 fitment; BEZT’s listed system covers those years for 2.7L and 3.5L EcoBoost engines.

This fits an owner of a listed 2015–2017 2.7L or 3.5L truck seeking a deep, aggressive tone and stainless construction. Its stated year and engine range is narrower than later-model options.

#9

9. BEZT Stainless Cat-Back

• Material Type: Stainless Steel
• Compatible with Vehicle Type: Car
• Weight: 36.7 lb

Best for: T-304 Single-Tip Fitment.

Why it ranks #9: The T-304 stainless cat-back lists 2.7L and 3.5L EcoBoost fitment and a 3-inch rolled tip, but its warranty is six months.

T-304 stainless steel and a three-inch rolled tip headline BEZT’s cat-back system, with compatibility stated for 2015–2020 F-150s equipped with 2.7L or 3.5L EcoBoost engines. A performance muffler is included, providing a defined component alongside the single-tip configuration.

The listed T-304 stainless construction and welded, flanged design are presented as durability features, while the performance muffler and three-inch rolled tip define the exhaust’s core configuration. Three-inch inlet and outlet connection sizes give buyers concrete connection dimensions. The product description says the system is easy to replace and includes clamps, with hardware and gaskets mentioned as pictured. Its fitment is limited to 2015–2020 2.7L and 3.5L EcoBoost F-150s.

Skip it if you own a 5.0L F-150; Flowmaster’s 2015–2020 FlowFX listing includes 5.0L applications, except standard-cab short-bed trucks.

A sensible candidate for a 2015–2020 2.7L or 3.5L EcoBoost owner wanting T-304 construction, a performance muffler, and a rolled tip. The listing does not cover the 5.0L engine.

#10

10. Flowmaster 717887 FlowFX

• Material Type: Plastic
• Compatible with Vehicle Type: Car
• Weight: 47.4 lb

Best for: Deep Sound Single-Side Exit.

Why it ranks #10: Its straight-through muffler and 4.50-inch black tip are specified, but the supplied listing does not establish EcoBoost fitment.

A straight-through FlowFX muffler and stated deep, powerful sound give this Flowmaster cat-back a defined acoustic character. The listing also specifies mandrel-bent tubing, factory-hanger locations, and a large 4.50-inch black ceramic-coated stainless tip for a single-outside-exit configuration.

The straight-through muffler and deep, powerful sound description make the tone the clearest reason to consider this system. Mandrel-bent tubing and factory-hanger mounting provide details about pipe construction and installation approach, while the 4.50-inch coated stainless tip specifies the outlet finish and size. The listing calls installation easy and quick. However, the supplied title and details do not state an F-150 model year or engine fitment, so application suitability cannot be established from these facts.

Skip it if you need an explicitly stated F-150 fitment; Flowmaster’s 717785 lists 2015–2020 engines and cab-bed exclusions.

This may interest a sound-focused buyer looking for a single-side exit, straight-through muffler, and large coated tip. The supplied information does not establish F-150 year or engine fitment, a key boundary before purchase.
