you can also try these -- Welcome to DMH Performance! -- I personally like the idea of push-button actuation (for greater control over sound and performance). The electronics don't wear out due to the heat, as is common with cheaper makes... If you really wanted the actuation to be automatic, you could always splice a WOT (wide open throttle) controller such as those used in NO2 injection systems quite easily.

Plus, they're not out of stock! :P

 

Id still prefer the VES. It works when it should, you can adjust when it opens w/ a mbc (optional), mechanical instead of electronic,and far less complicated to install with just adding a vacuum line instead of needing a wot controller.
