The FMF 4.1 RCT Slip-On integrates advanced Resonance Chamber Technology to balance acoustic performance with engine efficiency. A patented core shape reduces sound levels while preserving maximum power output, supported by a canister design that increases internal volume for enhanced sound absorption. The system utilizes a patented chamber structure to refine exhaust pressure, while Factory Forward Engineering centralizes mass to improve crash resistance. Each unit features optimized core specifications tailored to specific applications and includes an innovative rear end cap that simplifies the installation of tuning tip inserts or spark arrestors.
Available in two distinct material configurations, the Ti RCT features a titanium canister and mid-pipe, whereas the Aluminum RCT pairs an aluminum canister with a stainless steel mid-pipe. Both slip-on options include a spark arrestor and wash plug for compliance and maintenance. Complementing the exhaust system, the FMF Megabomb headers represent the next evolution in Powerbomb development, delivering substantial power increases across the RPM range. Riders can choose between lightweight military-grade titanium headers for reduced weight or stainless steel headers, which offer increased durability without compromising the performance characteristics of the titanium version.
