Description
Overview
Upgrade your 2022-2026 Toyota Tundra (3.4L) with the Flowmaster American Thunder cat-back exhaust system — a complete, bolt-on performance exhaust kit engineered to unlock better exhaust gas flow while delivering an aggressive-yet-refined tone. Built for the twin-turbo 3.4-liter Tundra, this catback exhaust replaces the restrictive factory piping with mandrel-bent 2.5-inch tubing crafted from durable 409 stainless steel throughout, so every component from the muffler to the tail pipe is ready to stand up to the road.
Key Benefits
At the heart of the system is a Flowmaster 50 Series HD muffler, tuned to produce a moderate sound level both inside and outside the cabin. That means you get a deeper, more purposeful note without the drone that plagues cheaper exhaust systems — a smart choice whether you daily-drive, tow, or just want your Tundra to sound as capable as it is. The 2.5-inch mandrel-bent pipes maintain consistent diameter through every bend, promoting smoother flow compared to crush-bent factory car exhaust plumbing.
The dual tail pipe design is finished with 3.5-inch polished stainless steel tips featuring an embossed logo, giving the rear of your truck a clean, custom look that complements the black-finished muffler and silver pipe color. Whether you’re comparing a Flowmaster against a Borla exhaust, Corsa exhaust, or MagnaFlow exhaust, this American Thunder kit is a proven performance exhaust option built to make your Tundra stand out.
Configuration Options
This exhaust system is offered with dual out-the-rear or side-exit configurations, so you can choose the routing that best fits your truck and your style. The muffler measures 24.00 inches in overall length with dual inlets and dual outlets, and a 2.50-inch outlet diameter for balanced flow.
Fitment & Installation
Designed specifically for the 22-26 Toyota Tundra with the 3.4-liter engine, this kit uses all the existing factory hanger locations — no cutting or fabrication required. It includes step-by-step installation instructions and all necessary hardware, making it a genuinely DIY-friendly upgrade you can tackle at home. It’s also CARB (California) compliant, so it’s street-legal in all 50 states.
