ok. i have a 93 coupe ex, with a b16 swap.
im going to need a new converter. but would i need to get it for the car or the engine..
or does it matter?

thanks

 

yours is fine.

 

I think you'd want to use the one from the b16. possibly upgrade to a hi-flow cat.

I'm bot sure what the smog laws are like in AZ.

 

guessing that your exhaust is not stock due to a swap. look into it, but i reccomend a basic hi-flow cat off ebat for like 50$, maybe less. but its a Honda, so its not like a cat has to work hard anyways. Generic high flow cats are fine.
