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.

Key Highlights

  • Full 304 stainless steel construction for durability and corrosion resistance
  • Signature Series straight-through muffler (18″ body length, 9″ width, 4″ height) tuned for a moderate, performance-oriented tone
  • 3.00-inch main piping with dual 2.50-inch inlets and a 3.00-inch centered outlet
  • Included exhaust tip with embossed logo, 5.00-inch diameter and 11.00-inch length for a finished, custom appearance
  • Uses all existing factory hanger locations for a bolt-on fit
  • CARB (California) compliant — Emission Code 5
  • Backed by Flowmaster’s Lifetime Limited Warranty

Easy Installation & Fitment

Designed exclusively for the 2022-2026 Toyota Tundra with the 3.4-liter engine, this kit installs at home using all the existing factory hanger locations. Every kit includes installation instructions and all necessary hardware, so you won’t need custom fabrication or a specialty exhaust pipe shop near me search to complete the job. It’s a genuine catback exhaust upgrade that swaps in behind the catalytic converters, preserving your truck’s emissions setup while transforming its exhaust flow and character.

Why Choose This Kit

Whether you’re comparing a Borla exhaust, Corsa exhaust, Magnaflow exhaust, or Walker exhaust for your Tundra, this Flowmaster Signature Series exhaust system stands out with proven rear-wheel dyno gains, premium 304 stainless materials, and a true bolt-on design. From the mandrel-bent exhaust pipe to the embossed-logo tip, every detail is built to enhance both the performance and appearance of your car exhaust setup. Add the moderate, aggressive-but-livable tone of the straight-through muffler and you have a complete exhaust system that upgrades your Tundra the right way.
