Description
Overview
The Flowmaster Flow FX Extreme cat-back exhaust system is engineered specifically for the 2022-2026 Toyota Tundra equipped with the 3.4-liter engine. Built to upgrade the factory setup, this complete exhaust system replaces the restrictive stock plumbing with free-flowing, performance-minded components that improve exhaust gas flow while delivering an unmistakably aggressive tone. If you’ve been searching for a catback exhaust that bolts on at home and transforms both sound and style, this Flowmaster kit is built to do exactly that.
Constructed from durable 409 stainless steel throughout, this performance exhaust is designed to hold up to the elements and the demands of daily driving and off-road use. The system runs 3.0-inch mandrel-bent pipes, keeping the exhaust path smooth and consistent for better flow, and pairs them with a straight-through Flow FX series muffler for maximum performance and an aggressive-to-moderate sound both inside and outside the cab.
Key Benefits
This car exhaust upgrade is all about a clean, functional install and real results. The system exits under the truck with a dump-style turn-down tip that adds style while improving ground clearance when you take the Tundra off the pavement. Every component is designed to use the existing factory hanger locations, so there’s no cutting or fabricating hangers required. The kit ships with installation instructions and all necessary hardware, making it a genuine at-home, DIY-friendly exhaust system for the weekend mechanic.
