hmf ecosystem

[wanta450]

does anyone know why hmf doesnt offer the ecosystem pipe for sport atvs since it is there quietest pipe

[Colby@C&DRacing]

the ecosystem runs the same back pressure as a factory utility exhaust they are seeing horsepower gains from the utilities using this system but isn't feesable to make them for a sport quad as you really won't see much gain on a sport quad.
