Yes, I understand the loud issue. My 07 had D&D 2-1 and was obnoxious but great power across the whole band. But after 8 hours in the saddle it took an hour for my ears to not hear the pipes.
I think the key to the numbers is the WB O2 sensors with Autotune. Auto's and planes have used WB sensors for a very long time. This allows the engine to change relative to gas, air temp, humidity changes in altitude etc.
I had the TMAT (Thunder Max on the 07 and it was great , but they don't have a version for the 09's).
I actually quieted my Rinehart's significantly with the pipe baffle material from Fuel Moto (30 bucks, yes $30). Took less than an hour start to stop. Quieted them down and changed the sound to a lower pitch.
All of this info came from Fuel Moto (Jaimie). They were great, set a modified map for my non-cat, Stage one and Rinehart's and let the PC V and auto tune take over.
Don't even feel the need to get it really Dyno's because I'm sure the Lazano brothers would want to tweak it. All race guys want to squeeze out every last bit of power.
I have two friends that have the Full Sac baffle replacement for the stock HD and they are not loud at all. Sound very good.
