It's not a must to install a header, but if you are looking for performance you might as well save your money and do the complete system to take full advantage of the gains.
The exhaust manifold has a large flange for the 1st catalytic converter to attach to. I haven't seen anything to replace the 1st cat with the exception of a header. You could remove the guts from the #1 cat and use the stock manifold. The 2nd cat would be were you place the hi-perf. cat. While you are there you might aswell increase the exhaust pipe to 2 1/4" and add a muffler...cost would be minimal. Your exhaust system is only as good as it's most restrictive point. Bosal/BroSpeed has a cat back style exhaust system, they also do R&D so your not buying a basement bargain system.
If you were to install a cat back exhaust to a high flow cat, all you have to do is modify the catback system to match the output of the hi-perf. cat.(not the other way around, the catback system would probably be designed to match a factory cat.)
This is basically my idea for some of my next years projects (this year is interior upgrades).
