I was at Carlisle and the Blockit was sold out, so I bought the demo kit that was inside the Corvette parked under the TKO tent. In my opinion, it was worth it because it works. My C6 is very loud, as it is cammed, etc., with headers & NPP. It has an annoying low rpm drone. With muffler flaps open it is unbearable for cruising below 1,950 rpms. Even with flaps closed, the drone was very annoying below 1,950. Most of my cruising is between 1,700 and 1,950 rpms in 6th gear with 4.10 gears. With the blockit installed, the drone is gone at these rpms with flaps closed. Not just reduced, but gone. Below 1,700 drone is reduced to a bearable level.
With muffler flaps open the drone is reduced with the kit, but still louder than my comfort level. But it's a moot point now.

No doubt Blockit really reduces noise levels & knocks down any drone...but to wipe it out in your case...awesome! 
Real glad you like it!

Take care
