Description
Overview
The Flowmaster Outlaw Cat-back Exhaust System is built for the driver who wants an aggressive, wide-open sound at all times. Engineered as a complete cat-back package, it replaces your restrictive factory piping with dual 3.00-inch mandrel-bent stainless steel tubing, race-proven Outlaw Series mufflers, and a signature look that matches the attitude. Everything you need for a straightforward at-home installation is included, right down to the parts and hardware.
At the heart of the system is Flowmaster’s exclusive Scavenger Series X-pipe, which ties both sides of the exhaust together to deliver a deep, unique tone while helping the engine make maximum power. The sound flows into a pair of Outlaw Series mufflers that give this kit its unmistakable, aggressive character, then out through quad 3.50-inch 304 stainless steel tips finished with an embossed logo for a muscular, purposeful presence.
Key Benefits
This exhaust is designed to sound aggressive on every drive, not just under hard throttle. Because it eliminates the factory exhaust valves, Flowmaster includes “dummy” valve stands that fool your factory actuators into thinking they’re still operating the OE valves. That means you keep the constant “wide-open” sound and performance without throwing a code, all while reusing your OEM actuator.
