We put them in our 2009 coupe. Without a sound meter, all I can say is that they provide a modest improvement in the noise with our stock exhaust and Michelin tires.
Cars that have a drone problem with an aftermarket exhaust, may see a greater improvement. Me, I'd just replace the exhaust in that case.

Bought it and sold it a week later. If it made a difference my wife and I couldn't hear it (we're in our late 20s....were just looking for something to take the edge off the drone on the freeway)
I would imagine it's good on a bone-stock car to help kill some road noise, but it does absolutely nothing to a longtube/loud exhaust car that has drone.
I'd move along and not waste your money.

Have it in our C5 with GHL exhaust and it helped the drone and road noise. Also have it in our 12GS and it helps the road noise a little and the drone with the NPP open. Think a front compartment wrap and this for the rear might really help road noise.

Well, I have not tried Blockit, but I did the full Dynamat. Borla Stingers were killing us with drone. They sounded amazing, but just couldn't live with them. After installing the Dynamat, drone was barely affected. Now running Corsa's, and very happy. And with the Dynamat, road noise is gone! That is what I can report:
