I have a 93 k1500 with a 350, I believe my right exhaust manifold has rusted off the y pipe (unless there's a gasket between the y pipe and manifold that's completely gone) So I need to fix or replace my manifolds. if I fix my OG manifold, what would i need to fix/replace? And if i get aftermarket headers I would like some that bolt right to the y pipe and the plugs are still accessible. Any suggestion would be greatly appreciated. Thank you and have a good day!
