I searched, but there were too many different answers..

Someone told me that they are the same, some told me that the eg is shorter...

thanks for any input before hand

cat came from b20 on eg
for B16 on 99 ek coupe

 

Are you talking about the EX catalytic convertor? Or the catalytic convertor in the exhaust manifold setup?

 

Yeah they should be the same, but the problem is I think the obd2 cars have an o2 sensor in the cat as well, and the eg hi flow cat might not have one.

 

thanks!!!

I had already converted it to obd1 so i shouldnt have a problem...
