Upgrade your race vehicle with the Flowmaster Outlaw Series Race Muffler, engineered for maximum horsepower and an ultra-aggressive exhaust tone. Designed for racing environments where a muffler is required but sound limits are not enforced, this compact high-flow design delivers pure performance with minimal decibel reduction.

The Outlaw Series uses a fully welded 16-gauge aluminized steel round case for extreme durability and high-temperature resistance. With no internal packing to wear out or blow out, your exhaust note stays consistently sharp and aggressive run after run. Its slip-fit connections and round compact body make it ideal for limited-space custom exhaust builds or direct mounting to header collectors.
