Smallest and Lightest Race Muffler

Flowmaster's Outlaw Race Mufflers are the smallest and lightest race mufflers to date, recommended for racing applications where a muffler is required without a set decibel limit. Outlaw race mufflers are designed to be connected directly to the header collectors or added into an already existing exhaust system. When attached directly to the collector, it generally produces more power than open headers, while taking the “edge” off that open header sound.
