FMF Factory 4.1 RCT Dual Muffler Full Exhaust System with MegaBomb Header

FMF's Factory 4.1 RCT Dual Muffler Full Exhaust System incorporates two mufflers with the latest in RCT (Resonance Chamber Technology) both internally and externally. Each core's shape lowers decibels without compromising power output. In addition, FMF designed the exhaust specifically to achieve a shorter overall length so as to be less susceptible to crash damage. Complementary to FMF's Factory Forward Engineering, the mufflers are also moved closer to the motor to centralize mass and improve handling. The Factory 4.1 RCT is constructed from only aerospace grade materials that meet the California company's exacting specifications.

Each exhaust comes with FMF's proprietary one-into-two MegaBomb header. The science behind the MegaBomb header actually reduces noise levels by as much as 1.5 dB when compared to conventionally-shaped headers to keep race and track officials happy. In addition, the header is designed to produce more low end to mid range gains as well as broadening out the mid to top end power gains when compared to the stock exhaust layout.
