    I just did headers on my 01 and ordered the TSP Y-pipe. After much custom welding and piping, things fit together for the most part. The factory Y wouldn't fit at all with LT's I went with. Started with the hooker ceramics, but sent them back and went with stainless with the AIR setup, so I can pass emissions here. I stayed with the SLP from the Y back, and it give it a bit of a rumble, but looking back, I wish I would have left things the way they were.

    Best bet is to go with a set -- LT's and a Y. Kooks, ARH, Pacesetter, Stainless Works, etc...

    most header companies make their own Y so you'll need the corresponding Y to whatever headers you buy. After that all the Y's should fit any catback.
