Pacesetter LT's and SLP y-pipe OK this is what i have, stock manifolds into cats, into a SLP Y-pipe, then into a bullit race muffler.....now what i need to know is, what am i going to have to do to get the SLP pipe to work with the new LT's i just bought......is there anyway to just put an adapter flange on the headers, b/c the y-pipe is bolt in on both sides....any ideas guys...or gals

It's going to need quite a bit of modification to work. If you have what I think you could remove the cats and possibly have it modified at an exhaust shop with slip fit connectors to the headers. But you might be better off just buying the pacesetter or tsp Y pipe.

Thats what i was wondering, I plan on 86'ing the the cats and just running the LT's into the y-pipe........I just wanted to know if anyone knew of an adapter that could go between the 2 or if im going to have to make my own...I guess i could look in jegs/summit and find some collecter adapters that would slip over the LT's and then have the same bolt pattern to bolt up to the y-pipe...or just get a whole new set and cut the old bolt in flanges off the Y......OR the really easy way and just order a new Y

I think you will have to cut the flanges off the Y but not sure. The connection point in the pipe for the LT's is going to be so much further rearward. Maybe not though. Either way it will take a little custom work to make it fit. I don't think you will find adapters that will bolt up to your Y and connect to the headers. A new Y would be cheaper and probably easier. Another thing to consider though, your car looks low. So is mine, and I had to "egg shape" my tsp ory under the driver seat, and put a dent in it to clear the trans crossmember and still have decent ground clearance.

the pacesetter y pipe does not have the fitment that their headers do. they usually bang the floor pretty bad. the TSP one is about the best y pipe you can get without going stainless.
