Im gonna be installing a 2.25" catback, with stock cat and an airmass header on my 95 D16. I just wanted to know what size gasket do I need between my cat and the header. Does it depend on the size of the header flange? Right now I have a custom exhaust and the cat is welded in, so I cant really match it w/the old one. Any help would be appreciated.

 

Anyone?

 

the stock one should work on it, ask the dealership for a stock header to cat gasket
