So I have a 92 hatch with a 95 gsr motor what cat do I buy ? Right now there is a test pipe in the car .I no longer have the old cat because it was ratteling .Integra cat or civic cat?Also what header gives you the most bang for your buck?I am not rich but would spend a little money extra for a good header.

 

It would probably be a Civic catalyst still I would imagine, unless you had to alter the catback when you did the swap. Why did you get rid of the old cat because it was rattling, did it break internally? A lot of times those rattles are just the heat shields.

 

yeah the cermaic inside was breaking apart

 

anyone

 

You just need an OBD1 cat, end of story
