I will be posting testing results in this thread.
We received the the DT system 11/9 and will begin the testing this week.
We expect the EMS system shorty and will test directly after.
The testing and review of each system will be conducted on two Land Cruisers with dyno results published from the same 2000 LC as the DT headers. The headers are in place so these tests will be DT headers + CatBack. Will be using the same facility and dyno as with the header tests.
We will be conducting sound tests both on-road and at idle using decibel meter. We will measure interior and exterior sound levels. We intend to record sound clips for your entertainment as well.
Both EMS and DT understand that the headers are in place and that results from dyno testing reflect that.
I will not be publishing any results until both systems are evaluated - this way no market advantage on the results will come to play. Again both EMS and DT know this.
Your comments and suggestions are welcome in this thread.

4/29/2013 update: I have attached results charts to posts 2 and 3. I will be posting additional commentary both here and my blog related to impressions, installation, etc.
DONT Compare these to the header results previously... Different Dyno and Different Tires (285's)
Vehicle: 2000 Toyota Land Cruiser
Mileage: 160,977 to 161,232
Configuration: DT Headers + OEM Catalytic Converters + Exhaust Tested
Variables:
Spark Plugs: OEM @ 139,003 miles
Airfilter: OEM @ 160,823 miles
Catalytic Converters: OEM @ 0 miles
O2 Sensors: OEM @ 157,518 miles
Fuel: Chevron (CALIFORNIA) 91oct
Engine Oil: Mobil 1 5/30 @ 160,823 miles
Diff / XFer Oil: Mobil 1 75-90 @ 143,804 miles
Driveline Lube: Sta-Lube Extreme Pressure Moly @ 160,823 miles
Throttle Body: Cleaned @ 160,823 miles
Tires: Goodyear Duratrac 285/75-16 (36PSI cold pressure)
Environment:
Superflow AutoDyn 30 – All Wheel Drive Chassis Dyno
Altitude: 42.7’ above sea level
Air Temp in Bay: 73*
Ambient Air Temp: 67*
Intake Air Temp: 107*
AT temp: 121 – 138*
Coolant Temp: 193*
Gear Selection: 2nd Gear Used (2nd Gear Start enabled)
* Each run was averaged for values within an exhaust group, then the 3 groups of runs averaged for the shown values.
Though 5-6 runs per system were conducted I took the best 3 runs of each and averaged the results.
Each system was installed and tested with new OEM gaskets and used supplied manufacturer hardware only for assembly. The original factory rubber hangers were used on each system.
