I have had my car less than a week. I have not driven around much in sport mode. Also, it has been extremely hot in my area of the country...even at night. So, to make a long story a little shorter, I was driving last night in sport mode with the windows down. I left from a stoplight...not like a crazy kid, but just a little more emphatic than usual. I heard this snarling, popping and burbling. My first thought was that someone in a new mustang gt was coming up on me from behind. Then I realized it was me. This car has one of the best stock exhaust notes I have ever heard.
