Exhaust gaskets
Hi everyone. As I wait for my Katech remote slave bleeder to be delivered today, I was browsing the webs and had difficulty finding replacement exhaust gaskets for each end of my Corsa X-pipe. My car still has the cats, and was looking for the round gasket at the base of each manifold and the joint at the axle back Borla. I came to find that auto parts stores near me (O'Reilly, Advanced, AutoZone) did not have anything specific to the car.
Does anyone know what C5 guys are doing for exhaust gaskets? I can't imagine they're only available form GM however, if they are, does anyone know of a page that has GM parts breakdowns to look at, to get GM part numbers?
Much thanks for any assistance here,
Cheers,
Ian

These are what I use for the axle back gasket. Much cheaper than the OE option.

I looked at that one, but it said it’s not compatible with the Corvette 🤷🏼♂️
