I recently swapped in a single cam VTEC engine into my 94 vx to replace the VTEC-E piece of junk that was in there stock. I retained the stock exhaust manifold due to the catalytic converter being integrated onto the manifold. I just bought an aftermarket header through mail order and haven't received it yet. I was wondering if the aftermarket header would match up to the stock exhaust pipe underneath without having to buy a catalytic converter from an EX civic. If anyone has actually tried please let me know.
Thank you
