Getting ready to replace my Catalytic converter Y pipe. I've ordered the studs and manifold gaskets for the front engine manifolds. I can't for the life of me find a gasket / hardware set for where the Y pipe goes to one and connects to the intermediate exhaust pipe. It would be the flange with the two bolts upstream of the muffler. Not sure it even has a gasket and I will just replace the rusty bolts with stainless. Nonetheless I'd like to have all items on hand before I dig into it. Any help tracking down that gasket (if there is one) would be much appreciated.

 

There is no gasket at that coupling I believe. Been a while since I fooled with stock exhaust, but I believe it's a ball and cup.

The studs are pressed into the flange on the converter side if I recall correctly, so those should not be an issue since you're replacing the y-pipe. If your pipe does not include new nuts you'll want those.

 

Thanks so much Alex

 

There is definitely no gasket. Check the mating surfaces before assembly. If it's rough or has grooves smooth it out.
