ATP used to have something like this and discontinued it for some reason. I read on some forums about an issue with them leaking over time. How do you address this issue? I think many of us pick exhaust systems for performance when with a device such as this we might pick one we really like for sound quality, but have the benefit of maximum performance. Kudos...
I personally can't wait to get a true dual quiet set up with cats, from Motordyne. I was anticipating having to manually remove the interchangeable components to achieve the level of performance my set up is capable of, but this is a great option... (if implemented well, hopefully)
EDIT: just saw video - looks well implemented, if somewhat bulky... very fast.

As far as the valve itself leaking over time.... the only thing that can cause that would be a build up of carbon etc . You can just pull the valve off and clean all of the sealing surfaces!! Any part that has dirty exhaust running through it over time will get dirty and may require an occasional cleaning. If you do not feel comfortable doing that yourself you can always send it to us and I will be glad to clean it to new specs for you!!

Wastegates are used to control the volume of air entering the turbo to control boost. If the boost is too high, they open and let exhaust bypass the turbo.
Exhaust dumps relieve back pressure in your exhaust system between the turbo and tail pipe. With an exhaust dump open you will make more HP at the same boost level due to less back pressure.

The site says VES-MAIN-VALVE-UNIT - out of stock again until unknown date due to production delays. But talking to them on the phone it appears that they are no longer producing it.
Looked like a nice piece except the pipe cut into you exhaust flow at 90 degrees which is not great for flow at all.

I ran into this thread when I failed to find any ATP VES cutouts. I have a mazdaspeed6, so I'm completely in the wrong forums, but I'm definitely interested in a 3" cutout! I'll be keeping an eye out on this thread - hopefully the cutout is available soon.

I am 'supposed' to be receiving the 3" versions of the valves today. If so I will post some pics of it in action at 15 psi!! It still opens very quickly!!
