RB Downpipe fit with stock cat?
I have an 86 N/A and was wondering if anyone knew if the RB downpipe will bolt up to the stock cat?

since it replaces the converter it is illegal and will not pass smog.

Well I just tried fitting it, but it didn't, too short. I was told that it was the RB downpipe but maybe it wasn't true. Just to let people know.
