Torchy, did you buy the SW catback designed for turbo applications? BBR has a catback by SW with upsized flow tubes so the inside diameter doesnt restrict down like the original. There was a post by someone on here (he was one of the first with hellion twins) where he disconnected his original SW mufflers and added another axleback (correct me if I missed something somebody). Gained some decent power from what I remember. The SW catback is the BEST sounding catback IMHO especially with turbos. PLZ post up a vid!
