Pete @ Strat, any discoveries as to what the exhaust valve does when the control line is cut?

Default Stays open. The vacuum is constant and keeps it closed. Milltek...

just did an inspection on their removed unit. -Pete, Stratmosphere. 1.866.533.1777

Default So there you have it. You can add a vacuum control valve to allow the exhaust to open up without

pressing the S button.

So when is Milltek going to introduce this feature and do I get a free exhaust for suggesting the idea? ;-D

Default Or you can just pinch the vacum line like on a R32, instant 10 HP.

Nice exhaust mod for $5... I LOVE IT.

Hmmm.... that looks painful. I don't think I want you to "get under there".
