Also if you're getting a code telling you it's a bad cat, I believe it means you have a bad pre-cat.. integral to the exhaust header. There's an O2 before and after the pre-cats, nothing after the main cat so a simple CEL won't tell you the main CAT is bad.... and if I'm wrong feel free to kick me.
