456 Acceleration 0 to 60, from inside the car

It's hard for me to tell because the sound of the video is warbly and digital, plus being in the tunnel makes it even more difficult. When he was outside the tunnel it didn't really sound all that loud untill he got into the upper RPMs just before the tunnel so I am thinking it is most likely a stock exhaust.

I used to live in OC (Mission Viejo). I miss it a lot to be honest although I love Tahoe also. I miss all the exotic cars along PCH in Newport Beach to Laguna Beach, and of course the ocean is always awesome. I go back from time to time.
