CA Perf Cat Delete Install Questions

I was actually able to pick up a set of CA Perf cat deletes used a little while back

Question I have is - does anyone know the GM PN# for the gaskets and (2) should I buy a new exhaust clamp for the driver's side pipe? (Not sure if they reuse the stock clamp or you have to cut the stock mid-pipe?)

No cutting, I think U use the old clamp. The only gasket was the rings in the down pipe to header, they are reusable.

Don't use the old clamp for the slip section...that is why guys complain of leaks.

This is what you want.

humm what is the ID of both steps. I assume 2.5 and 2.75

I liked and resused the silver sealant that was on the OEM slip joint. Don't know what that magic stuff was. I did NOT have any leaks. But it has been years since I ran the setup.
