Description
Overview
The Flowmaster Flow FX® cat-back exhaust system is engineered specifically for the 2022-2026 Toyota Tundra with the 3.4-liter engine, delivering a proven balance of added power, improved flow, and a custom look. Built as a complete bolt-on kit, this Flowmaster catback exhaust replaces the restrictive factory setup with mandrel-bent pipes and a straight-through muffler for cleaner exhaust gas flow and more usable performance from your Tundra’s 3.4L powerplant.
Constructed from durable 409 stainless steel throughout, this performance exhaust system is designed to stand up to the elements while maintaining a clean silver finish. The system runs dual 2.50-inch inlet piping into a single 3.00-inch exit, routing the flow through a Flow FX “straight-through” muffler tuned for a moderate, mild sound level that adds presence without droning inside the cab.
Performance & Sound
Flowmaster backs this exhaust system with real dyno results: gains of 11 horsepower and 12 lb-ft of torque over stock, measured at the rear wheels. The Flow FX muffler’s straight-through design maximizes flow over the restrictive factory muffler, so you feel the difference in throttle response while enjoying a moderate tone that suits daily driving, towing, and weekend trips alike.
Style & Fitment
The system exits out the side, behind the rear wheel, finished with a 4.50-inch black ceramic tip featuring an embossed tip logo for a custom, aggressive look. Because it uses all the existing factory hanger locations, installation stays straightforward — no cutting or custom fabrication of the exhaust pipe required. The kit includes installation instructions and all necessary hardware, making this a true at-home install for anyone who’d rather build the exhaust exhaust pipe setup themselves than search “exhaust pipe shop near me.”
