Overview

The Flowmaster Outlaw series muffler is built for drivers who want maximum flow and an unapologetically loud exhaust note. As part of Flowmaster’s aggressive Outlaw lineup, this muffler is engineered for race applications where raw sound and performance matter more than a set decibel limit. If you’ve been searching for a serious performance exhaust upgrade, this Flowmaster muffler delivers the deep, aggressive tone that defines a true race-ready exhaust system.

Designed for versatility, the Outlaw muffler can be connected directly to your header collectors or dropped into an existing exhaust system.
