I had to cut a short section of the cat-back off last night to fit the new Pacesetter y-pipe. And since SLP overtightened the clamp for the cat-back I couldn't separate the y-pipe from the intermediate pipe. So I had to cut through 2 pipes clamped together. Anyway, the stock y-pipe necks down to 2-1/2" id where the intermediate pipe clamps to it. And that's on an SS car! I can definitely see the longtube headers and y-pipe making a big difference.
