I just did a single cam turbo in a 93 cx hatchback and iw as wondering if just i have the cat back part of the exaust. and the down pipe but all i need is a cat so i was just wondering if just a single cam cat will work on it ?

 

if you have a catback an oem cat will most likely not bolt on
you're gonna need to get a custom one made

 

get a universal high-flow cat and get it welded on
