Wonderfully quiet when close absolutely insane when open. It's quieter than my rs3 with valves closed. I love this exhaust.

Never mind, just realized that the only difference is the exhaust tip colors.

They look to be pneumatic valves not electric operated.  I guessing they should hold up better?

When they go I'll replace them but I can't see them failing anytime soon.

Main reason I chose not to go with valvetronic exhaust was severe back pressure when valves are closed.  There's been dyno's done where closed vs open had significant power differences.  Definitely would not WOT when the valves are closed !  

 

The other was fear that the valves may crap out sooner or later.

Based on my experience with the HKS valved system it's also susceptible to rattling when the valves are closed. I thought maybe my adjustments were off but, listening to their own demo video, you can hear the rattling in the background when the valves are closed. Not a huge deal as I mostly drive with it open but just something to consider. Can also confirm you do feel a difference in power and spool with the valves closed.
