My 1991 DX smogged as a gross polluter. I checked out my O2 and found it was measuring very slowly asnwering why my CO was too high. Hydrocarbons were JUST BARELY over, so I found a "new-like" 92-95 civic EX cat.

The main question is has anyone bolted a 92-95 civic cat onto a 4Gen civic without issues?

Thanks in advance.

 

no one has ever tried to bolt in the newer cat on their old exhaust system.
