    • Q:

      Is this the gasket that goes between the exhaust manifold and the y-pipe on a 1993 Chevy C1500 5.0L? Is there anything other than the gasket and bolt set that I need to connect the manifold to the existing y-pipe?

        Happy to assist, Matt! Yes, it is, you would need 2 of the Walker exhaust gaskets #31398, 2 of the Walker installation hardware fasteners #36463 and one Dynomax bracket part #35362.
