Who has electric-actuated dumps? Do they leak when closed? Issues?

I've been thinking about them, too. I haven't heard any leakage complaints, it just seems
 

tough to find a good place to mount them. I know some people put them where their test pipes go (in lieu of cats), and then I found through someone else's suggestion that you could fit dumps and cats together - see link below. I would expect to have to do some periodic cleaning to keep dirt/crud off of the butterfly valve assemblies so they close correctly.<ul><li><a href="https://forums.audiworld.com/s4/msgs/2613623.phtml">https://forums.audiworld.com/s4/msgs/2613623.phtml</a</li></ul>

bertworks' is the nicest setup ive seen but even that is SUPER low
 

just take a look under your car sometime. the cats are like 5" off the ground max. if you push them back and add dumps there, its hard to not make teh dumps go lower.

im still thinking of ideas on how to make it work. maybe a longer y pipe like markp's and then have the electric cutout at the end of that ...

Those Bertwork's ones don't look to bad as far as fit. Mark Ps look by far more efficient though.
