Performance exhaust is all about flow, from the moment it leaves an engine’s combustion chamber, power and sound is all related to flow. Don Emler and his R&D team look at the whole exhaust picture and while the greatest potential for improvement on a four-stroke can usually be gained from the ‘back end,’ it all begins with the header. The FMF Hi-Flo header was the first step in maximizing this flow through the use of tubing size, materials, and unrestricted, freer flow movement. Hi-Flo headers are available for a number of four wheelers and a number of older motorcycles; and offer great value and durability.

FMF’s innovative and patented Powerbomb further raises the bar. The magic is in the “bomb,” it allows for improved flow of the engine’s power pulses but also utilizes FMF’s Hi-Flo concepts. Providing tractability, torque, increased rideability and up to a 1.5 hp increase, a Powerbomb header can bring that extra refinement in performance to any machine it is installed on. The Powerbomb is offered in weight saving performance titanium or durable stainless steel and is available for all current MX and off-road bikes and for racing and sport quads across a wide range of years.
