So I finally signed up to this website (long time lurker) with the intention to see what options I have for a tuner/exhaust combo for my 2010 Sportsman 800 EFI. Ive looked at websites big gun and HMF exhaust. I cannot find too many other options for my model ATV. Does anyone have any suggestions or experience with this model that could help me? Ive been undecided on this mod for my ride for some time tho it is something I really feel is necessary.
