waste of time. if you plan to go turbo your gona be wastin cash now unless you get like 2.5+ pipes wich will kill you in NA form. And a highflow cat is the best way if you plan to keep the cat, but you must get rid of that stupid cali spec downpipe cat. Better off not geting just a catback exhaust and redoing the whole thing. Otherwise you still have the headers and downpipe cat holdin you back anyway so...
