So I am wanting to get the tune at the PA event, but they said I need to remove second cat, or they restrict the tune to 220 wheel HP..
So what will I need to make this test pipe? I'd like to keep the stock resonator for now. I'd imagine that I would need to buy a straight piece of 2.5" pipe, and a flange to connect to the stock down pipe. Then weld the pipe to the stock resonator? What kind of flange would I get? Would it be a standard two bolt flange that I can pick up at autozone?
