Socom-You wouldn't happen to know how they change the legnth of the runners do you? The only 2 things I can think of are:

1) Using a sleeve system which may entail altering the position of the intake maifold either in part or the whole.

2) Using multiple hard pipes that are controled my a series of valves.

Either of these methods would case major design challenges.
