Headers and Catalytic

I've often read on the boards that there's no point in gettin an exhaust alone, since it'll make more noise than it will power.

Now that I've got the exhaust thing done, I was thinking about headers, intake and an aftermarket cat. Partnered with an exhaust, which one of these would make the most sense now?

Although, I don't want to race the car, I'd like it to be a lil quicker, as we know the accords start slow. Another thing is, I'm looking to add bigger tires and rims, so I'd like to at least gain back some of the speed I'll be losing with the added size and weight of the rims.

Thanks.
