C7 Coupe Noise
I ask a similar question about the C7 convertible, but am also interested in the coupe. I had a 2006 coupe and the road noise seemed to be worsened by the "drum" affect in the trunk area. In fact, my 2007 convertible was quieter since the trunk was partitioned off. Does the C7 coupe have the same issue or is the car quiet?

I had an 08 coupe and a 2010 gs vert and now the C7 coupe, and in my opinion none of the three I would consider quiet. The C7 coupe does seem to be a little less noisy than the other two though. I don't mind the road noise as I usually have my music turned up or the top off listening to the exhaust tone.

I had a body insulation kit installed in my C6 coupe which I drove for almost 6 yrs. Didn't realize how much difference it really made until I made the transition to the C7 (coupe). I think the Michelin tires make the C7 a little quieter but the coupe is still noisy on many road surfaces. I am presently looking into Dynamat and other insulation alternatives for the C7. After owning 4 vettes (2 verts, 2 coupes) the vert is definitely quieter.

After 8500 miles I'll comment that on some pavement the base C7 coupe on 18"/19" Michelins is remarkably quiet, quieter than any previous generation. But when you get on certain pavement textures the Michelins can transmit considerable tire noise into the cockpit where the rear area of the coupe amplifies it.
It's really surprising how quiet the base coupe can be on some pavement but really changes on other pavement.

I know you can't control road noise, but one of the big issues I am having with my 2011 GS convertible is wind noise. I don't know if I have a defect or the wide body is the reason. I would imagine wind noise is not a problem with the C7 coupe. True/false?

I ran a set of non-RF Michelin SS's on a Mini I had with a summer set of wheels. I found them extremely quiet on all surfaces compared to the Continental OE RF's. Of course that's apples to oranges. It will be interesting to see if and when someone wears out their RF SS's and they put on the non RF's if they are substantially quieter on all road conditions.

I had an 09 Z06. I had added rammat which is like dynomat then topped it off with another sound deadening insulation over that throughout the rear of the car, the waterfall and the tunnel. I was also running Nitto Invo 20/20 tires which were substantially quieter than the Goodyear run flats. Now I've got a C7 Z51 Coupe and I can tell you that the C7 is substantially quieter. Less road noise, less tire noise and best of all, no drone even with the exhaust open.
