regarding the cat, to make the header work better either have no cat, or use a high-flow cat (having no cat will give you problems with emissions laws but you may know a way round it  ). using standard cat with the performance header will still give you a nicer sound but probably no performance gain. you could put a resonator in instead of a cat for more back-pressure.
We dont have emissions tests around here... So as long as I can keep the CEL off, and a cop doesnt ask me to pop my hood... I should be alright...
