pulling the cat has yielded minimal gains if any. I wouldn't bother pulling it unless it's already given out on you.
With the welding, pipes, and frustration from fitting, you might be better off buying a lower priced catback. Check out the apexi n1. lots of folks have em, a little loud on the ka's but good bang for the buck.
