Lee has a 1992 they have the slip fit on the passenger side.

Some of the larger diameter cat-back exh systems had a slip over pipe with a triangular flange. My car came with a 3" B&B setup and had a 2-3/4's adapter pipe to a 3" flange. It was welded permanently.

I had to have a mating flange welded up on my Corsa. I prefer it this way anyhow because the slip fit might leak or be difficult to align at some point.

When my cats went bad and I had to replace both manifolds I had to beat that collector/flange with a rubber mallet damn near 100 times before I got it off. That thing was on there good.

Hello Brett,

I just found this after posting a WTB for this part you were looking for too. Were you able to the part you needed from Marc? It seems just like a typical header collector, but I don't find it in 3" to 2.75"; maybe I just get one of those and open up the 3" to
2.5" to 2.75" to slip over the pipe?

Thanks,

Craig

The gasket part # is 10147973 from GM. I'm not sure if this is still available. If it not I have a couple available.

Do anyone know where to get this gasket?
