Twin Scroll kits
As has been posted, we are offering twin scroll kits in both T3 and T4 configurations. Add just $500 to any of our Equal Length kits and we'll build your kit with a twin scroll manifold for a divided turbine housing turbocharger of your choice and include the extra wastegate and dump tube 
There have been a few of these kits sold just by special request so we've decided to offer them as an option

You need to look into all of your options also. I am pretty sure Nick at DTM has completed his TS setup and it is completely AWESOME! I was there from Newport News and saw one of his setups on a car that was on the dyno and it put down some incredible numbers and spooled very early. you would have to PM him to get specific numbers but I am saving for this kit on my car! And I am picky as hell when it comes to parts and my Evo! I told Nick that I was incredibly OCD when it comes to parts and tuning and such for my car and he took me on a little tour of his shop and then told me "I think you've met your match!" LOL

I was looking to do a 35R or 30R Twin Scroll with HTA treatment, Twin Scroll Header with 1 44mm wastegate, o2 and downpipe.
DTM and Shearer~ want to shoot me a price on each thing just in case If I piece it together? Because if Full Race is my only option then the twin scroll is just not for me....
I went to both of your websites and didn't see any TS stuff.

Yes, I have tried, fabricated and tested both. Absolutely not ONE difference in overall power, midrange response, tip in, low end torque, egts, nothing.
I have seen a solid 10psi across the board on an 8 psi spring, single gate, twin scroll mani with 2" runners, 3" down pipe and 42 R "style" Garret turbo.
One gate with a y collector coming from runners 1&3. The pulses need to stay "separate" until 1.5 inches to the merge point of the gate.

Interesting.
Why do the pulses not need to remain separate until they are expelled?
Don't you think it would be difficult to see if there was an advantage to running two wastegates up top at only 10 psi?
If there was a scenario where two wastgate runners were superior to having one merged where would you see it in restrictions in venting exhaust at very high rpm/boost levels or down low for spool up, keeping the exhaust pulses from mixing?
Thanks for your response Nick!
I am just shocked by those results. Most every "big name" divided t4 turbokit runs two wastegates, I am going to assume this is merely for the ability to run low boost with a huge turbo?
