Whats a good exaust kit to get for preformance?

I have a 92 RS, and everything except the flowmaster muffler is stock, im looking for a good kit that comes with everything, from the headers back to replace, im not sure if you can get kits with the headers, if so ill get one of them... Like to get a kit that has everything and just do the whole exaust in one shot... I dont need a kit with a muffler (do they even come with them?) I already have one, witch i like a lot, i just need a good preformance kit that would increase acceleration, and hp, etc, hopefuly make her sound a bit meaner also.. what are some good kits?
They usualy range around $600-900 correct?
Links would be very helpful.
Thanks a lot guys :)

Headers I'm not sure, but exhaust in terms of performance go Magnaflow, Borla, Loudmouth, TSP Rumbler or something else that's straight-through (or adjustable from fully muffled to fully open like Borla catbacks). You can't get a kit of just pipes w/o the muffler as far as I know unless you go custom, and if you do make sure it's madrel bent. I know you have your flowmaster loyalty or whatever but it flows pretty poorly compared to other mufflers, mainly due to the fact that they create their sound using chambers which in turn inhibit airflow.
