Alright I have yet another ? i hate asking again and again but this is the BEST site for answers especially with no one bitching....no joke. But anyway do any of you ARH owners have any loud cabin noise by dash and right under center console? Its like a loud roaring, im not sure if its suppose to be like that or if i dont have clamps tightened enough (tightened with 3/8 snapon cordless impact). Also anyone have any rubbing stuff like curbs with lowered mustang with long tubes? I thought about making up some hangers to add on to exhaust to help lift it because it sits real low. Any help would be appreciated. Thanks
