I want to get some feedback on this fmf exhaust before i go buying it. A buddy of mine knows a guy who put one on his 04 600, and went to go put some stuff on it to clean it and it messed up the anodized blue color, so he just sanded it and polished it, and said he'd sell it to me for $40. He said he bought it for around $400 like....2-3 weeks ago, so its not that old. What do you guys think? Im still ridin around on the stock pipe on my 05 750 and I cant stand it. I want a yoshi hi-mount but I'd like the slip-on hi-mount instead of having to pay for the whole headers and all, but they dont sell slip on hi mounts as far as I know.
