What should I do?

Ok, Im looking to put a new exhaust on my car, and I know the company I want to go with, that being flowmaster. Ive heard great things on the 40 series sounding really good with the 3.8 V6, which is in my car, but I was curious if anyone knew of any other good exhausts that will compliment the engine. My car is an 89 delta 88 coupe that, In my opinion has a bit of a sporty look to it and will soon be repainted in black, so as I said, any advice is much appreciated.

i have the flowmaster 40's on my car, sounds awesome everyone looks for the big truck or the muscle car, then they see my grand marquis!
