On a B18B, what header/cat combo will bolt up to a 92-95 Civic Hatchback exhaust? Not a stock exhaust but an aftermarket catback.

I went through this man... I couldn't find one to fit right. The B16 header won't work because it's not tall enough to wrap around the motor. The B18B header wasn't long enough to meet up. I didn't try the B18C1 header, but I'm pretty sure it's longer than the B18B one.

Just get the header for that motor and have a test pipe made to make it all fit.

I need emissions here in Ontario. It's going to be phased out in like 3yrs though, lol.

I'll just get a B18B header and have shop get a cat in there with a flange or if I remember right Power Core (Land Speed Racing) can get you a cat for any header/exhaust combo in any chassis. I'll have to talk to them.

Or just have a little mini pipe made to fit the gap between your header and cat.

GS-R header would probably be the shortest of all (at least OBD I GS-R header) the O2 sensor is in the beginning of the cat and the header flange is much closer to the front of the car. Just get a muffler shop to make you an extension pipe, cost me about $25 and never had a problem.

So use a GS-R header and cat?

Look at my pic, there's a 4-5 inch extension on the right side of the cat I had a muffler shop make to fit my '92-'95 Si exhaust system. I think regardless of what header/cat combination you use, your still going to need a muffler shop to make it all mate up.
