If you are looking for a agressive sound with acceleration and idle I highly recommend the GT500 style exhaust. I installed it last night in under an hour and I am really pleased with it and it is only $320.00. At highway speeds it doesn't drone out the cabin at all but when you get on it the car opens up.
