if its astock system there is the exhaust mani gasket, then the one at the down pipe from the exhaust mani, next there should be a dognut gasket at the cat, and a bi metal gasket at the exit of the cat, then last but not least the exhaust dognut at the muffler. this is for a 93 si hb I know there where some differances throught out that body style

 

if i remember correctly the doughnut gaskets are something like $40 each at the dealership here in atlantic canada, probably much cheaper in the US. but i seem to recall aftermarket being around $8 each, i think thats one of those times i'd go aftermarket.

I guess I don't sense the sarcasm, but yes AM gaskets are very inexpensive

 

you guys know where i can purchase the gaskets for the flanges and exhaust mani??! i find some of them here on Ht marketplace but i cant seem to find the complete gaskets for the exhaust..

the dougnut gaskets should only be around 8-10 dollars at the dealership, not sure about howthe exhaust manifold gasket is.
