SuperTrapp Stouts are massive 4-inch diameter slip-on mufflers that provide a bold statement and unsurpassed performance gains. These non-tunable mufflers are sold as a pair for Touring and Trike models and are designed to flow perfectly with either OEM head pipes or SuperTrapp True Duals. The internal core is engineered to provide a heavy, broad power curve right from idle, with recorded gains of 16% horsepower and 14% torque over stock on 2010 FLH models. They feature streamlined, internal tapered billet aluminum end caps with recessed fasteners and distinctive oval cut-outs. At 2,000 rpm, they produce a pleasant 95.6dB, offering a deep tone that is noticeably more authoritative than stock.
