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.
