Who makes external wastegate setup for cummins?

Just wandering if anyone else sells an external gate for dodge cummins trucks other than ED. I've been trying to get ahold of them, but no callbacks so far. So I need to find another route. Need a t4/t4 flange, piping with wg flange and wastegate. Any help will be appreciated.

Looks like a nice unit, but WAAYYYY too thick. I'd have to cut my shock tower off to fit that on.

Anybody else?

If space is a premium you might consider welding it directly to the manifold.

This is Dockboys pic, but thats the idea. Think thats how I`ll add a second secondary gate, the internal on the SS housing just don`t flow enough when you get into the 5k territory.

Basically stock if I would have built it at the factory.....

Ashley, mine is welded right to the manifold and i've got flexible dump pipe... it'll probably be available this winter if you're still in the market then

I noticed Garrett distributes the TiAl wastegates and blow off valves, so their distributors may have them or can order them. Here's the list:
06 Mega DRW, auto, 3.73, EFI Live, S&B intake, CFM+, Optix RP-boost-EGT-trans
