I need to order the correct gasket that goes between the exhaust manifold and the next pipe. It's a 1999 EX Civic. Rockauto shows a one-piece flat gasket for the 99 but Honda Parts Unlimited show two round gaskets. Can I use either one? I happen to have the one-piece gasket. I've attached the two photos from Rockauto. Thanks in advance.

 

Bump-Anyone?

 

go to a dealership and get the correct gaskets.

that flat one piece is junk for OEM manifolds.

the twin circles seal perfectly. They are also one time use by honda standards, but Ive found them to be reusable if in good condition (not rusted). Make sure the grooves they sit in is clean and free of debris. Makes the difference of sealing versus not sealing.

 

The exhaust manifold with the 4 tubes connects to the downpipe with the two tubes. The ones with the two separate flat gaskets are stock oem. So I'd go with those .
