well i purchased a used set of headers, and their all good, but of course the gaskets were bad, so i was wondering where i could get a good set of gaskets for the manifold to the head, and the headers to the downpipe and also from the downpipe to the cat....also when i put them on i kept my factory gasket on then put the new gasket over top and i was wondering that if my factory gasket was good if i could jus keep that one on instead of buying a new gasket there.

 

dealership, aka stealership for the head to maifold and downpipe to cat, (have not heard of problems with them)(also only use the replacement gasket not the old one too), as far as the manifold to downpipe idk, you proably have to contact the header manufacture (if it's not a universial one)

 

The mani to head gaskets you dont need to buy. reuse the stock ones. They can be reused. As for the other gaskets you need to say what kind of headers you have. Not all use the same gasket. the Y pipe to cat gasket can be bought at any parts store or honda/acura dealer.
