- The Flowmaster Outlaw Series Race Mufflers are our smallest and lightest race mufflers to date. When attached directly to the collector, it generally produces more power than open headers, while taking the ?edge? off that open header sound. These race mufflers are designed to be used at race tracks requiring mufflers, but without dB restrictions.

Asked by charle from sussex, NJ on
Hey Charle, the Flowmaster Exhaust Outlaw Series Race Muffler is designed by Flowmaster to be used for race vehicles. It is meant to be as close as possible to not running a muffler at all. It will be extremely loud. Please let me know if you have any other questions, thanks.
