b18c1 swap questions about cat converter
got a 95 civic si, swapped in a b18c1 and am having problems with the cat converter. Both the stock cat and the gsr cat are the same lengths, they are about 4 inches away from connecting to the header.. The gsr cat has an 02 sensor bung in it.. which cat SHOULD I need? I was under the impression that either would work but neither does.

Re: b18c1 swap questions about cat converter (crexer)
use the gsr cat because it has the o2 bung. just go to the muffler shop and extend the after the cat or you can have them weld you an extension with the 3 point flanges on each side if you don't want to cut your cat.
