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. Available in two compact lengths and tubing diameter sizes including 3.00″, 3.50″, 4.00″, 5.00″ and 6.00". Stainless Steel available too!
