Description
Overview
The Flowmaster Signature Series 22-26 Toyota Tundra (3.4) Exhaust System Kit is a complete cat-back exhaust system engineered specifically for 2022-2026 Toyota Tundra trucks equipped with the 3.4-liter engine. Built from durable 304 stainless steel throughout, this performance exhaust replaces the restrictive factory setup with mandrel-bent piping and a proven straight-through muffler for stronger flow, a bolder tone, and lasting corrosion resistance. If you’ve been looking to shop for exhaust upgrades that deliver measurable gains without the guesswork, this Flowmaster kit is a straightforward, home-installable solution.
Performance & Sound
At the heart of the kit is a Signature Series “straight-through” muffler that delivers a moderate sound level while maximizing performance over the stock muffler. Flowmaster’s dyno testing shows increases of 11 horsepower and 12 lb-ft of torque over stock, measured at the rear wheels. The dual 2.50-inch inlet and 3.00-inch single exit design, paired with mandrel-bent pipes, improves exhaust gas flow so your Tundra breathes freely under load. The system exits out the side, behind the rear wheel, capped with a stylish included tip for a custom look.
