FMF FACTORY 4 EXHAUST SYSTEM and MOTORCYCLE Pipe: A complete ‘front to back’ system consisting of performance matched components specifically developed for each particular model Our chief engineers managed to shift the already light weight of this complete FMF Titanium system in such a way as to lower and centralize your machine’s center of gravity which improves handling and critical clearances, all without sacrificing unmatched durability or silencer volume

The FMF Factory 4 exhaust systems consist of the new ‘FMF Factory Forward” FMF Powerbomb headers, custom matched mid-pipes, new oval to round anodized FMF Factory 4™ canister and an FMF “Remove before Flight” washplug While these systems were built to perform with stock jetting specifications, for optimum response we also include an FMF Power Up jet kit for those riders wanting the most from their investment includes at no charge a Power Up jetting kit for optimum jetting tuneability and their "remove before flight" wash plug with every Factory 4 System sold.
