I've got 3" from the Y pipe back and I get off the line fine if I can get traction. It really opens up the top end when teamed up with a ram air kit. I've got stock tubular manifolds, 3" pipe in place of cat, 3" S pipe, 3" American Thunder cat back.

If I had it to do over again I would have left the cat and put an exhaust dump on remote just before the cat to really open up the top end. It sounded so nice before I took off the cat, not it sounds really nice below 3,000 but not so great above but the gain was great. I might have tried to just chop off the end of the stock cat and mate it to a 3" pipe. Only thing that could hurt is while welding it could melt some of the filter crap.

i ended up getting a 98 + I pipe and it turned out it was missing the S. so i call hpsalvage and he says the older Zs include the S as one piece. i go back to hpsalvage and he gives me another pipe and it includes the S as one piece. how cool is that? he said it was off a 93 or 94. it should get put on sometime next week.

All 1993-1995 LT1 Exhaust kits aftermarket are 3" and include the S pipe.

ok the setup is done and i dont think i can do anything else with air going into or out of the motor. it sounds really really good. the other day i was at a stoplight in my truck (cause of my broken valve guide in my car) and i heard a mustang GT drive off. i realized it sounded good as it was driving away, but i heard nothing when we where just sitting there.
my car sounds good just sitting there, idling its own business, and sounds even better as it drives off. all in all i am very happy with how it sounds.

I have 3" Catco Cat, 2.5" piping, and 2x2.5" after the muffler. I truly am glad I didn't go to 3". I will be running NA for a while. I felt just a little tiny low-end loss, and I gained a good amount top end. Where I really gained was in the 55mph-65mph area. Now, when I pass cars, it jumps a lot more than it used to. I like the 2.5" - 2.75" pipes.
