Unless things have changed, the only way to get one is factory installed on the car. Even if it were sold separately it would cost thousands, probably $3,000.
(Mostly) Posted by Josh/AWE. Flapper valves are open at idle, close after 1100 RPM during part throttle. Full throttle 1st-4th gear the valves open until throttle let off. 4th gear, 1500 RPM to full throttle closed, closed until 3500 RPM, then open until lift off throttle.
