The new GTM exhaust replaces the GT which gets rid of the metalic rasp and brings the exhaust pitch up a little bit.

Damn that is loud. And definitely drones as well
How can you tell it drones?

I have the gt exhaust and it doesn't drone much at all. Actually it's pretty pleasant as a daily driver and pretty quiet at cruising speeds. Albeit I do not have the gtm exhaust, my point is that drone was never a problem to begin with and for RPI to address that aspect in the gtm is interesting.
