FMF pioneered Factory Forward engineering; moving the muffler further forward in the frame, shortening the midpipe and muffler length to centralize mass and lower the center of gravity for improved handling. Take the angle cut canister a distinct look that separates FMF from the pack. There is our exhaust port flange that transmits less vibration and puts less tension on the header. There is our proprietary muffler packing incorporating various substrates of wire mesh, high density fabrics and advanced sound absorption material FMF’s packing is arguably the best in the industry. Where others skimp, FMF beefs it up to give you unmatched reliability.
Anyone can make a bolt on system, but not anyone can give you the innovations and patent pending technology FMF offers or the quality from making each exhaust ourselves. FMF Racing is performance. Bolt on a Factory 4.1 and FEEL THE POWER!
