FMF is one of the top players in the game when it comes to high-quality, high-performance exhaust systems. The all-new FMF Factory 4.1 RCT Anodized System with Carbon End Cap is no exception. The latest in Resonance Chamber Technology from FMF, the Factory 4.1 RCT muffler features a five-sided canister designed to regulate sound better than ever before. With more room to accommodate packing material, along with a patented core design housed in the canister, the Factory 4.1 RCT exhaust adequately absorbs the sound coming in to the muffler and regulates it to produce a great tone – all while preserving maximum power output. The new design also features a shorter canister, which helps to centralize the mass weight of the bike. It also makes the system less susceptible to damage in a crash due to reduced muffler length extending from the bike. 

Paired with the muffler in the Factory 4.1 RCT system is the FMF Titanium Megabomb header pipe. A uniquely constructed 4-stroke exhaust designed to help you dominate the racing scene, the Megabomb can produce as much as a 3hp increase when matched up with the Factory 4.1 RCT muffler. The Megabomb is specifically designed to produce more low to mid-range power, but still broadens out the overall mid to top end power when compared to the stock exhaust.

Made in house in the U.S.A. and constructed out of the finest, aerospace grade products, the Factory 4.1 RCT Anodized System with Carbon End Cap is precision made to exacting specifications to noticeably boost your bike’s overall power and performance, and to give you the cutting edge advantage out on the track.
