No, my car is the sleeper. Looks like a stock V6 Mustang except for the window tint and wheels. Everything else about it screams "Base model V6". But it's has a Procharger under the hood, new shifter, carbon fiber drive shaft, X-pipe exhaust, new adjustable suspension with the rear lowered so it sits flat and level (Front is still at stock height though), clean air filter, and custom tuned. It's dynoed at 437hp to the rear wheels which means it's pushing about 50hp more to the rear wheels than a GT, but weighs about 250lbs less.
And you can't really tell it's anything other than a stock V6 until I jump on the
throttle and that supercharger starts to whine.
