This new SuperTrapp Slip-On boasts a 92dB sound level compared to the stock 87.5dB sound level (per SAE-J1287 off-road sound test). The SuperLight provides a deep, throaty, growling sound.The SuperLight Stainless Series for the BMW R1200GS is constructed of 100 percent 304-grade, Stainless Steel with a Polished Finish for high-end quality and looks without the high end price tag.SuperLight Stainless Series are a tunable, internal disc-based Slip-On. Meaning, they utilize SuperTrapp’s legendary, patented diffuser disc technology which allows a rider to control the performance, sound and flow of their bike by simply adding or subtracting discs. The SuperLight includes eighteen, 4″ discs. Adding 4″ discs provides more sound, horsepower and flow. Subtracting 4″ discs will reduce the sound and flow, but will increase the low-end torque.The SuperLight weighs only 9 lbs.
