Bartman,

Thanks for all the additional info! Ive decided to just go for the HMF setup maybe with the "quiet core". I was talking with a friend they run a shop and he said they got a slip on for a 400ex and the guy gave them a report after a week of riding. Evidentally the guy loved their pipe I guess he replaced his FMF pipe with it and said he could tell a good power increase over his old one plus it wasnt any louder either. Im hoping their Raptor setup will be just as good if not better with their "full system" Plus I keep hearing nothing but good about them. All I gotta do now is save the $$$ =-)
