The RCT (Resonance Chamber Technology) system is a patented design that reduces decibels without sacrificing the maximum power developed by the engine. The Factory 4.1 RCT exhaust pipes are constructed from materials used in the aerospace industry and meet the conditions and specifications required by FMF Racing. They are 100% manufactured in the factory in Southern California, USA. The "spark arrester" insert and QuietCore 94db are included. The weight is significantly reduced and power is improved across the entire RPM range.
