The HMF Swamp Series was designed specifically for quads that need pure, all out horsepower. Through the deep, muddy waters to the starting line of the GNCC, the Swamp Series blisters power that gives you absolute control. It features a 5" stainless steel exhaust and produces very little sound dB over stock. And with the optional HMF Quiet Core, most machines can see a dB decrease over stock!
----------------Swamp XL Series--------------
The cousin of the Swamp Series, the Swamp XL Series delivers the same insane power as the Swamp Series but with an unrestricted sound level. If you want to be heard tearing up the track or busting through the woods, the XL is the pipe your looking for. Also in a 5" stainless steel can, this beast will give you all the power and noise you can handle.
