Well the best is the HMF but it is also the loudest. Cobra exhaust is the only one I can think of at the moment that is easy on the pockets and not to loud with some performance gains. If I can remember some of the others I will post them.
i got mine for just a little over $230 (shipping included) on ebay newI am really not concerned about the noise when I am pouring on the power but I am concerned when I am idleing and just off idle trail riding!
Because I do ride it alot when I am hunting. I did price out a stock replacement and it was about $220, How much is the HMF?
