Neil i'm serious, Turbonator are really pushing their products into OE cars, according to this .PDF there's talk of a 25bhp increase, and a nice 38ft/lb torque.
You heard how the XKR sounded on TG last night with that Supercharger? Well with the addition of an exhaust spinner too, that is nothing on this new 197 Turbonator.
Mark my words, the Hoff speaks truth!
