Ive just posted a similar question about the difference in noise between the standard plenham and the roller barrels, and after seeing these vids wow, I mean WOW..!!

so I need to know how much this is going to cost above the price of the car.

The difference is even greater from the driving seat in every way, including gratuitous levels of popping and banging on the over run . On full throttle you can almost imagine you are driving an early 70-s F2 car..well I can anyway (it may be my inner Ronnie Peterson talking )

My 7 w/ 260 hp Cosworth Duratec (roller barrel TB) at Sonoma Raceway (used to be called Sears Point):

edit -- Great sound, DCL! 2.0 Duratec, I presume? Sounds more "edgy" than my 2.3

It's a 2L big valve CNC2 head with a large bore 4:2:1 exhaust, so about as open as you can get .
