92b18cx

just like the title says which cat would I use for a obd1 b18c1 is a 92 cx hatch? I am planning on ordering one but should I order the civic or gsr? Also I am planning on getting an apexi ws2 in the near future as well.

They are the same cat. The only way you will get a direct fit one that will bolt to the header and then to a catback is if you buy one that is specific to that swap. If you go with custom piping from an exhaust shop or have an exhaust shop fill the gap, any cat would work. The best thing to do in your case is to buy an aftermarket cat such as a Catco that isn't flanged and have an exhaust shop size and fit it up with flanges.

I don't know if this will help out or not, but when I get my swap I'm thinking about getting custom piping and then Spoon N1 axel back exhaust from there. Just an idea. Hope I did some assistance to you.
