When I put on a whole new system, the gasket/seal/donut from Advance auto didn't fit the exhaust pipe at the manifold..too big in diameter, even though it was listed as the correct part. I went to the local dealer & bought one, which fit like it's supposed to. So, be careful of some of the auto parts stores parts !

 

Agree completely.

Interestingly, I bought that gasket from my local Autozone as their store brand is a repackaged Felpro for that gasket on a 95.
