Hello all... Just finished my H23 swap into my 93 Accord. The H23 that I got came with the exhaust manifold. So I left it on the engine and my Accord downpipe bolted right up to the H23 exhaust manifold. My question is I am looking to but a header for it so do I buy a Prelude header or a Accord header? Are the H23A1 and F22A6 exhaust manifolds the same? Thanks in advance.
