I want to put a high flow cat on my newly swaped B16A CRX DX. What do I buy it for the CRX or the Civic SI? I bought one for the CRX and am waiting for it to come in the mail. I got the Apexi World sport too.

 

same part

 

Thanks I wasnt sure, someone told me I had to get the one for the 99 Si since thats the same engine and all.
