Many forum members have been very pleased with the sound of a simple muffler delete. Get an exhaust shop to replace your factory mufflers with straight pipe and weld the tips on. Costs about $100-$150. The factory cats and resonator do about 85% of the muffling of noise on these cars. It might be something to look into, and save some money for other mods.
As for a cold air intake, there is the Z-28 intake from GM, Roto-Fab, CAI brand, etc. They are all good. Search the forum and read up. Take your pick.
