As stated in my earlier thread I currently drive a 2013 Dodge Challenger. The only things I've done to it so far are replace the front bumper fascia (I hit a mailbox the first day I had the car), the left rear bumper fascia (I got rear ended), and put in a K&N CAI. I considered replacing the exhaust and adding a box tune, maybe porting the throttle body, but the thing is basically hopeless as a muscle car. Pathetic power/weight ratio.
