With the exhaust, plenum and Softronics map changes, the car definitely feels stronger with more torque in the low and mid range. Not as much at the top end. As for track times, I only dropped about a second on a 2.5 mile track. Certainly less expensive than getting an 'S' but worth $3,000? I'm not so sure. AP exhaust sounds awesome and no drone. The whole install was fairly easy if you are a good DYI. Happy holidays and best of luck.
