Chasek TA

i didn't know what thread to post this in but if figured this would be the best one. Anyway my 87 Trans am Gta with a 5.3 is getting close to done. i just order some parts from hawks to finish it up. The 5.3 is stock with ls1 intake and hawks long tubes. i think 2.5 inch exhaust would be best. It will be dueled out. I just have no idea on what mufflers to get. i want something pretty loud. i was thinking flowmaster 10 series or dynomax race bullets. but any opinions or other options i should look at? thanks
