i am going to go with (buy) a corksport 'power series' cat back (that attactches to the stock cat), and racing beat headers. is the only solution to connect the two a racing beat presilecer? i was looking for somthing a little cheaper and less shiney. i dont care about brand name. i just need somthing to connect the headers to the cat back. would a plain old 2.5" wide pipe work? how loud would this be?
