What Kind of Exhaust Should I Get?

Sooooo many choices. If you still have the stock H, I would start with replacing that because you get increased volume of the stock exhaust and performance too. Easy job to do this in your garage also. Magnaflow X with cats if your in a state that checks visually and for emissions would be my vote. If your just looking for sound, you can weld in some mufflers i.e. flowmasters are popular, but watch for drone at the 2k rpm range if you replace mufflers.
