If I use it to replace my manifold will it bolt up to my cats? I'm thinking about doing it but don't have the extra money for the presilencer yet. Just planning on gutting the cats for now but gotta make sure the header will fit.

No, racing beat header won't bolt up to the cat. Corksport offers a header that fits with the stock cat.

Sorry to jump in on this but how good is that header?

It won't bolt up, but if you take it to any reputable exhaust shop they will be able to patch it up.

I installed the RB header a long while ago on my NA and just sawzalled the rest of the exhaust system to a shorter length. I drove it open header to the shop and had them install a piece of pipe with a flange welded to it to bolt to the end of the header. Since then I have replaced the rest of the exhaust system.
Hell, get them to just cut the cats out and add in a few feet of pipe between your header and the Y pipe.
