Exhaust. No question. Also do you have any kind of engine management?? If not you really need it soon. Especially with the intake. These cars don't like to be modded without tuning. Take a look at the faqs all over this site. Lots to learn
ps. Btw. The catback won't get you any power but while you are at it might as well do the downpipe and get a tune. I would avoid the bov. Your car won't like it. I had one for a while and found that i was running bad at idle and constantly getting backfires. Put a stock Bpv on and it runs so much better. No more backfires. Plus the stock Bpv is good for around 20 psi of boost. So no need for aftermarket ones right away. At least on the older cars...
