okay hears what im thinkin, i have peirs twins so that gives me a true 5inch downpipe from the turbo so from their i want to run 5inc pipe and bend it up into a single 6inch miter stack. to me this set up looks tough but will it be absoltely unbearable?if so thats great after all im 18. i dont want to have to buy a setup i would rather piece it together my self only problem is i cant find any local muffler shops with a 5inch pipe bender,try a big rig shop maybe?
