has anybody used this? i told the guy 200 bucks and he said he'd take 200 for it so its a good price but do these make power or sound good.

I dont use the exact same one, but I do have the titanium-4 and the fmf hi-flo header. Ive liked it so far. Its a bit louder than I would like. I did just repack it and haven't run it yet. I like that they are customizeable. Im thinking about getting the quiet core and the spark arrestor for it. (around $60 for both). Its deffinately lighter than the stock pipe which I like. Most of the FMF's get you a pretty good power increase. Theres a shootout somewhere if you search for it. It ranked pretty high but they didnt like how loud the fmf's are. I tell ya what that thing flows like crazy. I knocked a full pop can off my other quad 20 feet behind me from crackin the throttle.
