It really depends on what your goals are for the car and what sound your looking for.
If you are looking for the best performance and the best opportunity for later modification you are going to want a pair of headers.
Then you have to determine your best combination of performance and sound. Allot of people like the flow, sound and performance of the Borla namebrand. Magnaflow i believe gives around the same performance but they are a bit cheaper. They give a low rumbling sound. I was advised to stay with the 2.5" cat back [for n/a and s/c gp's, 3" for turbo] but i suppose different people will say different things.
Flowmasters so im told don't go well with our cars, the only good thing about them is the unique sound and they give more low end power.
If you are more concerned about power, get headers and a 2'5 cat back from borla. If you are concerned about sound then go on youtube and type in "grand prix exhaust note" or other similar things.

more grand prix drama....ive had my car for 3 years now, i installed the dynomax cat back 6 months after i purchased it. it is not rusted through and i live in New York City!!!!!! i am however changing the mufflers back to stock because it drones too much with no cat. just because some crybaby claims the cat back rusted through doesn't mean they all will. hell my 85 regal and 86 442 the factory exhausts just had surface rust on them before i took them off.
as for the size it is 2.25 piping but it is bent nice than stock, there are no kinks in it as say a muffler shop would do. it sounds very good as long as you keep the cat, once i installed my 2.5 DP it was way louder. id rather hear my m90 than the mufflers
