The best cat-back exhaust system is the one that fits your exact vehicle configuration before it changes anything else. We compared six current systems by model-year and engine fitment, cab or bed exclusions, tubing material, pipe size, muffler and outlet design, stated sound, and installation details.
Quick picks
We screened 16 Amazon US listings and ranked six available ASINs from four brands. Confirm fitment with the manufacturer before ordering.
Borla 140753BC ATAK Ram 1500 Cat-Back System
Borla publishes the most complete premium package: explicit 2019-2023 Ram 1500 V8 fitment with the Classic excluded, T-304 stainless construction, all-welded bolt-on assembly, ATAK sound, dual split rear outlets, and 5-inch black chrome tips. Its stated no-drone guarantee is unusually clear, though buyers pay a major premium.
- 2019-2023 Ram 1500 V8 fitment; excludes Classic
- T-304 stainless, all-welded bolt-on construction
- ATAK sound, dual rear exit, 5 in black chrome tips
The listing identifies model years, V8 application, E-Torque inclusion and Classic exclusion, reducing the most common compatibility ambiguity.
T-304 stainless steel, all-welded construction, bolt-on installation and USA manufacture form the strongest documented build in the group.
ATAK sound, dual split rear outlets, two 5-inch black chrome tips and a published no-drone guarantee create the clearest premium sound-and-style package.
Flowmaster 717864 FlowFX Ford F-150 Cat-Back Kit
Flowmaster 717864 balances a well-documented 2009-2014 F-150 application with 3-inch 409 stainless mandrel-bent tubing, a straight-through FlowFX muffler, and a large black ceramic-coated 304 stainless tip. It reuses factory hanger locations and includes hardware, making the ownership path clearer than most mid-priced listings.
- 2009-2014 F-150 3.5L EcoBoost, 4.6L, 5.0L, 5.4L
- 3 in 409 stainless tubing with straight-through FlowFX muffler
- 4.5 in black 304 stainless tip; factory hanger locations
The listing identifies model years and four engine families, then states factory-hanger use and included hardware.
Mandrel-bent 409 stainless tubing, a 304 stainless tip, straight-through muffler, included hardware and a limited lifetime warranty are thoroughly documented.
A deep powerful tone and single 4.5-inch black ceramic-coated side tip are clearly described, though cabin sound is less explicitly qualified than Borla's drone claim.
MBRP S5262AL Ford F-150 Pre-Axle Dual Cat-Back
MBRP S5262AL is the most distinctive packaging choice for a 2015-up F-150: the listing excludes the regular-cab short-box configuration and routes two outlets ahead of the rear axle. T409 construction and mandrel-bent 3-inch tubing are stronger published material details than typical budget systems, but engine and cab coverage still deserve confirmation.
- 2015-up Ford F-150; excludes regular-cab short-box
- T409 construction with mandrel-bent 3 in tubing
- Pre-axle dual-outlet layout
The listing states the model-year range and an important regular-cab short-box exclusion, though engine coverage is not detailed in the title or bullets.
T409 construction and mandrel-bent 3-inch tubing provide strong core build evidence, with less detail on hardware and warranty than the top two.
The compact pre-axle dual-outlet layout is clearly differentiated for buyers who want outlets ahead of the rear wheel, even though sound wording is limited.
MBRP S5338P Toyota Tacoma Cat-Back System
MBRP S5338P is the clearest value pick for the listed Toyota Tacoma 3.5L application. It uses mandrel-bent 3-inch aluminized tubing, bolts on, and exits on one side with a stated performance tone. The tradeoffs are meaningful: the Amazon bullets name only 2016 fitment, while other current references describe a wider range, and the system does not include a tip.
- Published Toyota Tacoma 3.5L fitment
- Mandrel-bent 3 in aluminized tubing
- Bolt-on single-side exit; tip not included
The exact Tacoma 3.5L application and bolt-on design are stated, but the checked Amazon bullets specify only 2016, so later model years must be confirmed separately.
Mandrel-bent 3-inch aluminized tubing is credible at the price, but it lacks the stainless grades and fuller hardware documentation of higher-ranked systems.
A single-side exit and performance-tone claim are useful selection cues; the absent exhaust tip adds a separate purchase and finish decision.
Flowmaster 17395 American Thunder Truck Cat-Back Kit
Flowmaster 17395 targets a narrow but clearly described classic-truck configuration: 1999-2007 Classic Silverado or Sierra 1500 with 4.8L or 5.3L power, extended cab, and short bed. Its Super 40 muffler, 3-inch 16-gauge aluminized tubing, dual polished tips, factory-hanger use, and included hardware make it a complete aggressive-sounding package.
- 1999-2007 Classic Silverado/Sierra 1500 4.8L or 5.3L
- 3 in 16-gauge aluminized tubing with Super 40 muffler
- Dual 3 in polished tips; moderate-to-aggressive exterior tone
Engine, cab, bed and Classic-platform details are explicit, but the wide year wording still calls for a VIN-level configuration check.
The system includes 16-gauge aluminized tubing, Super 40 muffler, hangers, hardware and stainless tips, but the main piping is not stainless.
A moderate-to-aggressive exterior tone and dual 3-inch polished tips clearly suit buyers prioritizing traditional American Thunder character.
DNA Motoring CBE-HC922-NRT Honda Civic Cat-Back
DNA Motoring is the budget stainless option for the published 1992-2000 Honda Civic coupe or sedan fitment. The listing specifies T-304 stainless steel, computerized mandrel bends, and a TIG-welded CNC flange, unusually strong material language at this price. Its deep aggressive tone is clearly stated, but engine, transmission, emissions and tip details need separate confirmation.
- 1992-2000 Honda Civic coupe or sedan fitment
- T-304 stainless with computerized mandrel bends
- TIG-welded CNC flange; aggressive deep tone
The year range and coupe/sedan bodies are explicit, but engine, transmission and emissions-configuration detail is not published in the checked bullets.
T-304 stainless steel, computerized mandrel bends and a TIG-welded CNC flange are standout construction claims for the price.
The aggressive deep and smooth tone is stated, but outlet and tip dimensions and cabin-drone behavior are not documented in the checked record.

How we ranked these exhaust systems
This is a desk-research comparison. BestStuffGuide did not install these systems or measure power, torque, cabin noise, exterior sound, drone, corrosion, clearance, or durability. We screened 16 current Amazon US listings, removed universal systems and products without usable fitment evidence, and kept six complete cat-back ASINs from four brands.
Fitment clarity accounts for 45% of the Editorial Rating. We credited only explicit model-year, engine, cab, bed, wheelbase, body-style, and exclusion language. Materials and build contribute 30%, using published tubing grades, diameter, mandrel bends, welds, mufflers, tips, hardware, and warranties. Sound and exit design make up 25%, based on stated sound profile, drone behavior, outlet location, tip size, and finish.
Fitment comes before sound
A cat-back usually begins after the catalytic converter, but that does not make systems interchangeable. Pipe routing changes with wheelbase, cab and bed length, drivetrain, suspension packaging, bumper openings, spare-tire clearance, and factory exhaust layout. Match the exact year, engine, cab, bed or wheelbase, drivetrain, and original outlet configuration.
Borla is clearest here because the listing calls out the Ram 1500 V8, includes E-Torque, and excludes the Classic. MBRP’s S5262AL identifies a regular-cab short-box exclusion. Flowmaster 17395 narrows its fitment to Classic Silverado or Sierra 1500 trucks with specific engines, extended cab, and short bed. These details are purchase gates, not minor footnotes.
Use a manufacturer lookup even when Amazon says it fits
Amazon’s vehicle filter can be a useful screen, but confirm the part number in the manufacturer’s application guide. Compare the listing’s configuration with the vehicle identification number, emissions label, and current exhaust. If the system includes multiple mid-pipes or cut locations, read the installation instructions before ordering so you know which wheelbases and body lengths they cover.
Stainless versus aluminized steel
Borla 140753BC and DNA Motoring’s Civic system publish T-304 stainless construction. Flowmaster 717864 uses 409 stainless tubing with a 304 stainless tip. MBRP S5262AL lists T409 construction. These grades are not identical: 304 is generally chosen for strong corrosion resistance and appearance, while 409 is common in exhaust tubing and can show surface discoloration.
MBRP S5338P and Flowmaster 17395 use aluminized steel for the main tubing. Aluminized systems can be a sensible value in a dry climate or on a vehicle that does not see frequent road salt, but exposed cut edges, welds, clamps, and impact damage deserve inspection. Do not describe a stainless tip as evidence that the full system is stainless.
Pipe size, mufflers, and outlet layout
Every truck system in this shortlist publishes 3-inch main tubing, but diameter alone does not establish performance. Mandrel bends, muffler restriction, pipe transitions, engine tune, and the rest of the exhaust all matter. The seller’s horsepower claim on the DNA listing was not used because we did not find independent testing tied to the exact reviewed configuration.
Outlet location affects appearance and practical clearance. Borla uses two rear outlets through the Ram bumper area. Flowmaster 717864 exits at the side with a 4.5-inch black tip. MBRP S5262AL puts dual outlets ahead of the rear axle, which avoids long tailpipes but can change where sound and heat leave the vehicle. MBRP S5338P uses a single-side exit and does not include a tip.
Sound labels are not measurements
ATAK, FlowFX, American Thunder, performance tone, and aggressive deep tone are manufacturer or seller descriptions. They help distinguish intent but are not comparable decibel readings. Cabin sound varies with engine, cylinder-deactivation behavior, gearing, cab insulation, wheelbase, load, and installation quality.
Borla’s checked listing includes a no-drone guarantee, the clearest ownership promise in this group. Flowmaster 717864 describes a deep powerful tone, while Flowmaster 17395 states a moderate-to-aggressive exterior tone. MBRP S5262AL provides the least sound detail, so choose it for packaging and construction rather than a precisely documented sound target.
Installation and legal-use checklist
- Confirm exact model year, engine, cab, bed or wheelbase, drivetrain, and factory exhaust layout.
- Use the manufacturer’s current part-number lookup and installation instructions.
- Check whether clamps, hangers, gaskets, adapters, and tips are included.
- Support the vehicle and exhaust with properly rated equipment; never rely on a jack alone.
- Work only on a cool exhaust and protect eyes and hands from rust, sharp edges, and falling sections.
- Verify clearance around fuel and brake lines, wiring, suspension, spare tire, bumper, and body panels.
- Align the system before final tightening, then recheck clamps after the specified heat cycles.
- Confirm local noise, inspection, warranty, and emissions-related requirements before modification.
Frequently asked questions
Will a cat-back exhaust add horsepower?
It can reduce restriction on some applications, but gains vary with the engine, factory system, pipe design, tune, and test method. We did not use seller horsepower claims in the rankings because they were not independently verified for each exact configuration.
Is T-304 stainless always better than 409 stainless?
T-304 generally offers stronger corrosion resistance and a more stable cosmetic finish, while 409 is widely used for durable exhaust tubing and often costs less. Climate, road salt, fabrication quality, welds, and warranty matter alongside the grade.
What is exhaust drone?
Drone is a sustained low-frequency cabin resonance that can become tiring at steady engine speeds. A sound described as aggressive outside the vehicle does not automatically predict cabin drone. Look for application-specific manufacturer guidance and owner feedback tied to the same engine, cab, and exhaust configuration.
Can I install a cat-back exhaust at home?
Many are described as bolt-on, but seized fasteners, heavy sections, limited ground clearance, misaligned hangers, cutting requirements, and exhaust leaks can make the job difficult. Use proper lifting and support equipment, and hire a qualified exhaust shop if the instructions or vehicle condition exceed your tools or experience.
Does a cat-back exhaust affect emissions equipment?
A correctly designed cat-back normally replaces components downstream of the catalytic converter, but legal treatment and inspection rules vary. Confirm that the exact system preserves required sensors and emissions equipment and is permitted where the vehicle is registered and driven.
Final verdict
Borla 140753BC is the best overall choice for a compatible Ram 1500 because it combines the clearest configuration language, premium T-304 all-welded construction, bolt-on installation, a distinctive dual-rear ATAK layout, and a published no-drone guarantee. Flowmaster 717864 is the strongest stainless value for the listed 2009-2014 F-150 engines. Choose MBRP S5262AL for a pre-axle dual exit, MBRP S5338P for Tacoma value after model-year confirmation, Flowmaster 17395 for traditional classic-truck sound, or DNA Motoring when budget T-304 construction matters and its Civic fitment is verified.
