The issue with this car would be the catalytic converter not oxidizing the way it should. How big is the converter/exhaust and is it still in the stock position?
the converter is from magnaflow which i ordered online and is universal:
Inlet/Outlet Size: 2.5"
Overall Length: 13"
Body Length: 9"
Width: 6 1/2"
Height: 4"
OBD 1 & 2 Approved!

As for the the catback i got a skunk 2 mega power specifically for a 88-91 crx (d series)used. So i took it to muffler shop to get some flanges and get it custom since the header is from a b series and the catback is from a d series.
