I have a catback and headers on my 92 EG8 and my catalytic converter rusted and snapped. So is it ok if I just put a pipe in place of my catalytic converter.

 

Do you have to pass emissions? If so then no.

 

Won't hurt you car but it's illegal.

 

I don't have emissions, here they only test OBD2 they dont put the cars on belts anymore.

Will i have any problems with the o2 or CEL? I don't know much about exhaust systems.

 

If you're running OBD2, and have no catalytic converter, it will probably throw a CEL from your secondary O2 sensor. If you want to run a straight pipe without the constant CEL, you can get an O2 sensor simulator.

Or if you want to do it the right way, Magnaflow makes universal cats you can weld in, and they're relatively inexpensive. When I replaced mine, it was cheaper to have the shop cut the flanges off my test pipe and weld them onto the Magnaflow than it would have been for a direct replacement. They also flow fairly well.

 

I'm running obd1 and just looking for a cheap alternative. Is it ok if i just use the pipe and dont get a new cat?
