Here, I ran the blue car with all stock as it was originally received, the green car has all the other mods up to this point, and the red car has the Borla exhaust. The difference at the end of the run shows the stock car moved 1771.0 feet, the car with the stock exhaust went 1824.8 feet, while the car with the Borla exhaust has gone 1833.6 feet.
