so i guess a friend of mine had the SLP on his '00 vette and he said it was so loud on the highway that he couldn't hear himself think. he's trading it up for the stock '00 Z06. i still haven't gotten a sound clip for the Mustang though. can anyone help me out? i am still curious. even though i have driven my friend's vette, and can attest to the racetrack-ready sound, that is a completely different car. any help would be great. thanks.
