The rear of the car is actually pretty sexy looking aggressive with the large quad pipes built into the diffuser. The widebody work is pretty well done especially the fenders. In black without the ridiculous scoop on the roof the car would likely look very aggressive.
XXX-Performance claims 650 horsepower out of the 5.2 V10 with software and exhaust modifications. AudiBoost claims BS and conveniently there is no dyno graph to support the claims. It's their word versus ours and considering what other tuners are getting out of the motor their word holds little water with no support. A tuner should be required to back up these kinds of claims.
