The FMF Factory-4.1 RCT Aluminum Silencer features a bigger volume can which can utilize more packing material for better performance and longer lasting low output sound volume. The RCT in the front end of the exhaust is another huge added gain for sound and performance. The FMF Factory-4.1 RCT Aluminum Silencer is sound compliant with the FIM 2M Max sound test.
