But I don't know, I might go with an expansion kit if this is too loud or the power increase too minimal. Thank you for sharing =)
Don't buy a cheap pipe and don't worry about EPA certified, That just means it's restricted with more carp. These engines are nowhere near EPA certified anyway. A GOOD expansion chamber would be the way to go. A lot of guy's on this site even make their own. Check around and do the research as to what chambers really work. I tried a cheap expansion chamber on my cruiser and it was worse then the stock pipe.
