Hey fella's, haven't found a concrete answer on this yet so I figured I'd ask.

I've currently got a 97 EK1, D16Y4 with a short ram. I'm looking to do the exhaust next and with my current monetary situation I can only afford bits at a time. So I was looking into throwing an Ebay 4-2-1 header on just for the hell of it. My first car being modified, don't care much for price or quality just doing it to get the know how for later endeavors.

The problem is, the particular set I'm looking at says direct bolt onto stock system, however I'm slightly worried about it connecting to the stock cat. Would I have to purchase another cat? Or would the headers bolt on without the need for that?

Cheers in advance.
