heckler Posted July 7, 2009 Share Posted July 7, 2009 I'm 99% sure CW decat is 2.5" (as I used to have one), how ever, a 3" pipe will bolt to a 2.5" as they use same size flange Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted July 8, 2009 Share Posted July 8, 2009 I have only made 3 three inch de cat pipes and i know where they all are, so it'll be a 2.5 inch one. Quote Link to comment Share on other sites More sharing options...
