Best Tundra Cat Back Exhaust for Different Builds and Sound

#1 · Best Overall

1. Flowmaster 717664 FlowFX Cat-Back Exhaust

• Weight: 56.5 lb
• Material: Plastic
• Material Type: Plastic

Best for: FlowFX dual-exit sound seekers.

Why it ranks #1: Lists compatibility across 2009–2021 Tundras and several engines, with dual 2.5-inch mandrel-bent 409 stainless tubing and factory-hanger installation.

A straight-through FlowFX performance muffler gives this kit its deep, powerful performance sound, while dual 2.5-inch tubing directs exhaust to its side exits. The 4.5-inch black ceramic-coated tips add a larger visual accent for Tundra owners seeking a dual-out Flowmaster system.

The 16-gauge, mandrel-bent 2.5-inch tubing is specified to maximize exhaust flow, while the straight-through muffler is intended to shape sound and performance. Factory hanger locations support installation using the existing mounting points, and the system clears the factory spare tire. Its 409 stainless-steel construction is specified for long life. The listing covers 2009–2021 Tundras with 4.0L, 4.6L, 4.7L, or 5.7L engines and 2WD or 4WD, making its engine and drivetrain range a key fit check.

Skip it if you want 3-inch tubing; Flowmaster 817692 lists that diameter and an aggressive Super 10 muffler.

This is a sensible match for Tundra owners seeking FlowFX tone, dual side exits, and a broad listed engine and drivetrain range. Confirm your truck falls within the 2009–2021 fitment and choose it for its 2.5-inch tubing.

#2 · Aggressive Sound

2. Flowmaster 817692 Outlaw Cat-Back Exhaust

• Weight: 32.72 kg
• Material: Plastic
• Material Type: Plastic

Best for: Aggressive towing-focused setup.

Why it ranks #2: Covers 2009–2021 Tundras and pairs stainless construction with a Super 10 muffler, 4-inch black tips, and side exits.

A Super 10 performance muffler and side exits give this Flowmaster an aggressive sound, with towing applications specifically called out. Its 3-inch stainless-steel cat-back uses mandrel-bent tubing and large black ceramic-coated tips, making it a match for Tundra owners seeking a conspicuous dual-exit setup.

The kit uses factory hanger locations and includes the necessary hardware, which supports an installation using the truck’s existing mounting points. Flowmaster says it clears the factory spare tire, a practical consideration when retaining that equipment. The 3-inch mandrel-bent stainless-steel construction pairs with the Super 10 muffler for a performance-oriented exhaust path, while the 4-inch black ceramic-coated tips and side exits give the rear of the truck a distinct finish. Listed fitment excludes Regular Cab Short Bed and Double Cab Long Bed configurations.

Skip it if you have a Regular Cab Short Bed or Double Cab Long Bed; this listing excludes those configurations.

This suits Tundra owners wanting an aggressive, side-exit cat-back for towing use, especially those who value factory hanger locations and spare-tire clearance. Check the listed cab and bed exclusions before choosing this configuration.

#3 · Stainless Tips

3. Borla 141023 S-Type Cat-Back Exhaust

• Weight: 65 lb

Best for: S-Type stainless-tip preference.

Why it ranks #3: The listing identifies 2009–2021 Tundra fitment and 4.6L or 5.7L V8 compatibility, with 4-inch stainless tips.

Borla’s S-Type designation pairs with 4-inch stainless tips on this cat-back for 2009–2021 Tundra 5.7L applications. That combination makes it a clearly differentiated option for owners seeking the named Borla sound family and a stainless rather than black chrome tip finish.

The listing identifies the system as a Borla S-Type cat-back and specifies 4-inch stainless tips, giving buyers two concrete selection points: muffler family and outlet finish. Its stated 2009–2021 Tundra fitment and 5.7L engine designation define the application to check. The supplied facts do not state tubing diameter, installation hardware, material for the rest of the system, or exit configuration. Those omissions limit comparison on installation and exhaust layout, even though the model and tip finish are explicit.

Skip it if you prefer black chrome tips and an ATAK system; Borla 141024BC lists those features for 5.7L Tundras.

This suits 5.7L Tundra owners seeking Borla’s S-Type cat-back and a 4-inch stainless-tip finish. The listing does not provide tubing diameter or installation details, so account for those unknowns when evaluating fit and setup.

#4 · Moderate Sound

4. MagnaFlow 15306 Cat-Back Exhaust

• Weight: 70 lb
• Material: Stainless Steel
• Material Type: Stainless Steel

Best for: Comfortable street-sound priorities.

Why it ranks #4: Specifically designed for 2014–2021 Tundras, its Street Series description targets moderate exterior sound without sacrificing comfortable interior noise levels.

MagnaFlow’s Street Series targets enhanced exterior sound without sacrificing comfortable interior noise levels, making this cat-back a street-oriented choice for 2014–2021 Tundras. Fast-flowing mandrel-bent pipes and larger or more straight-through mufflers are specified to reduce exhaust restriction and deliver its performance tone.

The Street Series description balances exterior sound with comfortable cabin noise, a useful distinction for drivers who want a more noticeable exhaust without the stated racecar-level attention. Fast-flowing mandrel-bent pipes and larger or more straight-through mufflers are described as reducing restriction and enabling MagnaFlow’s performance tone. The kit is specifically designed for 2014–2021 Toyota Tundras and uses stainless-steel construction. Its listed focus is street sound and fitment, rather than an explicitly named exit layout or muffler model.

Skip it if you need a named muffler and dual 2.5-inch tailpipes; Truck Exhaust Kits Shopline specifies both for its setup.

This suits 2014–2021 Tundra owners seeking a street-focused performance tone while keeping interior noise comfortable. The supplied listing does not name an exit layout, so buyers needing a specific outlet arrangement should account for that boundary.

#5 · T-304 Construction

5. SPEEDFX MaxFlow Xtreme Exhaust

• Weight: 72.1 lb
• Material: Stainless Steel
• Material Type: Stainless Steel

Best for: Stainless durability and fit.

Why it ranks #5: Uses T-304 stainless steel and mandrel-bent angles; the listing also describes optional dual side or dual rear exits on applicable systems.

T-304 austenitic stainless steel is the central material feature of the SPEEDFX MaxFlow Xtreme, which the listing says will not pit or rust. Smooth mandrel-bent angles are intended to support airflow, while CNC manufacturing to exacting tolerances is described as reducing installation time.

The T-304 stainless construction and 300-series stainless weld filler support the system’s stated durability focus, giving buyers material details beyond a generic stainless designation. Smooth mandrel-bent angles are intended to maximize airflow for sound and performance. CNC manufacturing to exacting tolerances aims to create precise fitment and reduce installation time. The listing identifies the application as a 2009–2021 Tundra and notes optional dual-side or dual-rear exits on applicable systems, so exit selection depends on the particular applicable setup.

Skip it if you need an explicitly named muffler or pipe diameter; Truck Exhaust Kits Shopline lists its Super 44 muffler and 2.5-inch tailpipes.

This suits Tundra owners who prioritize T-304 stainless, mandrel bends, and precision-oriented manufacturing. The listing spans 2009–2021 trucks, but exit options vary by applicable system, so confirm which configuration matches your intended layout.

#6

6. Borla 141024BC ATAK Cat-Back Exhaust

• Weight: 62.1 lb

Best for: ATAK tone and black-chrome finish.

Why it ranks #6: Lists 2009–2021 Toyota Tundra 5.7L fitment and 4-inch black chrome tips, making it a targeted option for that engine.

Borla’s ATAK designation and 4-inch black chrome tips distinguish this cat-back for 5.7L Tundra owners seeking that specific model and finish. The listing identifies compatibility with 2009–2021 trucks and names the system as a replacement for the Tundra ATAK cat-back exhaust.

The product is identified as a Borla ATAK cat-back for the 5.7L Tundra, with fitment listed for 2009–2021 models. That combination makes engine and model-year matching the main compatibility checks supported by the supplied information. Its 4-inch black chrome tips provide the named outlet finish, while the cat-back format identifies the system category. The listing does not specify tubing diameter, installation hardware, material construction, or exit layout, so those details cannot be assessed from the available product facts.

Skip it if you need stainless tips rather than black chrome; Borla 141023 S-Type lists 4-inch stainless tips for 2009–2021 Tundras.

This is aimed at 5.7L Tundra owners who want Borla’s ATAK system and 4-inch black chrome tips. The supplied details do not establish tubing diameter or installation contents, so weigh that information boundary against your requirements.

#7

7. Flowmaster 717786 FlowFX Cat-Back Exhaust

• Weight: 46.4 lb

Best for: Same-side FlowFX exit fans.

Why it ranks #7: Specifies a same-side dual exit and compatibility with 2009–2020 Tundras using 4.6L, 4.7L, or 5.7L engines.

A dual same-side exit gives this Flowmaster FlowFX system a specific layout for Tundra owners who prefer both outlets on one side. Its title identifies 4-inch black ceramic tips and 409 stainless steel, pairing a distinctive tip finish with a named exhaust-system material.

The supplied description identifies the system as a FlowFX cat-back and gives fitment for 2009–2021 Tundras; the title specifies 4.6L, 4.7L, and 5.7L engines. That makes engine and model-year matching central to the buying decision. The 4-inch black ceramic tips provide the listed outlet finish, while the 409 stainless-steel specification identifies the system material. The provided information does not state installation hardware, hanger arrangements, tubing diameter, or sound level, so those details cannot guide a comparison here.

Skip it if you need listed details for tubing diameter or supplied hardware; Truck Exhaust Kits Shopline specifies 2.5-inch tubing and included hardware.

Choose this for a Tundra owner prioritizing a dual same-side layout, FlowFX branding, and black ceramic 4-inch tips. The supplied details leave tubing diameter and installation contents unspecified, so those considerations may require a better-documented option.

#8

8. Borla 140332 Cat-Back System

• Weight: 52 lb

Best for: True-dual Borla enthusiasts.

Why it ranks #8: Lists true-dual construction and T-304 stainless steel, but fitment is restricted to specified 2009–2013 cab, bed, and wheelbase configurations.

Borla identifies this as a true-dual cat-back, giving Tundra owners a specifically stated layout rather than a generic dual-exit description. T-304 stainless steel, all-welded construction, and bolt-on installation define its materials and installation approach for listed 2009–2013 V8 configurations.

The all-welded construction and T-304 stainless steel specify how the system is built and what material it uses, while bolt-on installation points to a connection approach that does not call for welding during installation. Borla describes its sound as classic BORLA sound. Fitment is narrowly detailed for 2009–2013 4.6L or 5.7L V8 automatic trucks with specified 145.7-inch wheelbase cab and bed combinations; buyers should match those details rather than rely on model year and engine alone.

Skip it if you need a listing that covers Tundras through 2021; Borla 141023 S-Type lists 2009–2021 fitment.

This is for owners of the specified 2009–2013 automatic V8 Tundra configurations seeking a true-dual Borla system with T-304 stainless construction. Its detailed wheelbase and cab-bed limits are central to fit selection.

#9

9. Truck Exhaust Kits Direct Fit Dual Exhaust

• Weight: 60 lb

Best for: No-weld dual conversion shoppers.

Why it ranks #9: Fits stated 2009–2021 Tundra applications and includes a Flowmaster Super 44 muffler, hardware, and a no-welding installation claim.

No welding is required for this Truck Exhaust Kits setup, which converts a Tundra’s single exhaust to dual tailpipes. The kit combines dual 2.5-inch mandrel-bent aluminized tailpipes with a Flowmaster Super 44 muffler, and includes hardware for installation with basic hand tools.

The custom Y-pipe and dual 2.5-inch outside-diameter tailpipes create the listed single-to-dual conversion, while the included Super 44 muffler supplies the specified muffler choice. The manufacturer says no welding is required and that basic hand tools can be used, making the installation approach clear for a buyer planning a home garage project. Fitment covers 2009–2021 Tundra half-ton, eight-cylinder applications across all wheelbases. The tailpipes are aluminized, not described as stainless steel.

Skip it if you want stainless-steel construction; SPEEDFX MaxFlow Xtreme specifies T-304 stainless steel and 300-series weld filler.

This fits Tundra owners planning a listed 2009–2021 half-ton, eight-cylinder single-to-dual conversion, particularly those seeking a no-weld approach. Its aluminized tailpipes are the key material boundary for shoppers comparing stainless systems.

#10

10. BEZT Single Muffler Cat-Back Exhaust

• Weight: 35.7 lb
• Material: Stainless Steel
• Material Type: Stainless Steel

Best for: Single-muffler replacement buyers.

Why it ranks #10: Covers 2009–2017 Tundra 4.6L and 5.7L V8 models with stainless steel construction, but lists a six-month warranty.

A performance louvered-core muffler and single 2.5-inch outlet define this BEZT cat-back for 2009–2017 Tundra 4.6L and 5.7L V8 models. Stainless-steel construction, computerized mandrel bends, and included bolts and gaskets make it a clearly specified single-muffler replacement package.

The stated fitment is limited to 2009–2017 Tundras with 4.6L or 5.7L V8 engines, so later model years and other listed engine sizes fall outside this product’s supplied application. Stainless steel and welded, flanged construction are described as supporting durability, while computerized mandrel bends are intended to preserve the system’s shape and impact resistance. The 2.5-inch round single outlet and louvered-core muffler identify its layout; included bolts and gaskets provide listed installation hardware.

Skip it if you have a 2018–2021 Tundra; Flowmaster 717664 lists fitment through 2021 and covers several engine sizes.

This is for owners of listed 2009–2017 4.6L or 5.7L V8 Tundras who want a single-muffler, 2.5-inch cat-back with hardware included. Its model-year and engine limits are important fit boundaries.
