Yes, i read the sticky. My exhaust is rusting out and I want to replace it with a higher volume piping. I saw the god awful u bend, I'm going to bypass it but my question is, what size is the stock piping? Should I replace the resonator with a glasspack? Should I reuse the factory muffler or go with something different? I'm trying to pick up a little horsepower here without breaking my wallet. I'm going to take my car to an exhaust shop. I have a 1998 GTP 184K
