Mmm thats the route I wanted to go Doc, but I'm not sure what the loss of back pressure will do to my performance, Rob ran with his open but I haven't seen anything where he's run with his normal exhaust who knows he may have gone quicker?
I do remember reading on the forum here awhile back that supercharged cars dont need any back pressure. I cant seem to find the thread though.
