I just tried to see what my time would be 0-60 in my new stingray. I have the bi-mode exhaust and had it set in track mode. It's an auto and I wasn't using the paddles. When I started and it shifted from 1st to 2nd I heard what sounded like a back-fire out of the exhaust. I'm thinking that maybe this could've been the exhaust and not engine backfire I hope. Anybody else had this experience? It did 0-60 in 4.5 sec.
