Interesting, but:

In addition to the supercharger, Callaway adds a liquid-to-air intercooler, high-flow intake, low restriction exhaust, and larger fuel injectors. Appearance upgrades include under hood build plaque, carbon fiber injector covers, Callaway badging, dash plaque, embroidered floor mats, door sill panels, Callaway key fob, and authenticity documentation package.

How much lower restrictive than the factory version could their exhaust possible be and still be legal?
