Description
Overview
The Flowmaster® Outlaw Extreme cat-back exhaust system is engineered specifically for the 2022-2026 Toyota Tundra equipped with the 3.4-liter engine. Built to unlock better exhaust gas flow while adding serious attitude, this complete catback exhaust kit swaps out the restrictive factory setup for a purpose-built performance exhaust that looks, sounds, and flows the way a Tundra should. If you’ve been searching to shop for exhaust upgrades that bolt on without cutting corners, this Flowmaster exhaust system delivers a proven combination of durability and aggressive tone.
Constructed from durable 409 stainless steel throughout, the system is designed to stand up to heat, road spray, and off-road abuse for the long haul. The 3.0-inch mandrel bent exhaust pipe design keeps the flow path smooth from end to end, helping the engine breathe more freely compared to the crimped bends of a factory car exhaust. At the heart of the kit is a race-inspired Outlaw series muffler that measures 16.75 inches in overall length, with a center inlet and center 3.00-inch outlet for a clean, efficient exit.
Sound & Style
This is where the Outlaw Extreme earns its name. The Outlaw muffler produces an aggressive to moderate sound level that makes itself known inside and out, giving your Tundra a commanding presence without being obnoxious around town. The system exits under the truck with a dump-style turn-down tip, a design choice that not only adds rugged style but also improves ground clearance for off-road driving. The pipes carry a silver finish while the muffler wears a black finish for a purposeful, high-performance look under the truck.
