Pretty vague post, so here goes.

If you're just doing bolt-ons, then Comptech 4-2-1 is pretty ideal. (you didn't mention anything about price)

Otherwise go with a full hytech setup.

If you're running a supercharger, go with a Kamikaze.

This all depends on what diameter piping you're going to use. 2.25? 2.5? 3? Header collector/cat/catback should all be of the size diameter.

You might want to be a little more specific. Check up on the pricing for the headers I listed above h:
