I just spent a week traveling in my wife's 2012 Grand Sport convertible. I loved the performance but I'm getting too old for the noise.
I went through the same thing with a C5... slow learner. I used the Frost King stuff... not that much improvement.
I've got 4 Michelin Super Sports coming. and I'm going to give my best shot at sound insulation. Now I'm soliciting advice from the forum.
I see that most all popular approaches use a double foil backed foam. Being an engineer, it seems to me that any foil applied directly to body panels will not stop the sound waves as much as dead air space (foam) between the two. I'm thinking of gluing a thin layer of foam to the body panels first, and then applying some sort of foil sandwich. This would create two layers of foam insulation. Make any sense?
Please... if you have no direct experience with this subject save your post. I know this forum. lol

There are a ton of positive post. Here are some from forum members..

I can still hear the nice sound of the engine & exhaust, but without the annoying road noises. Very pleased with this purchase.

The mat looks very polished in the rear cargo area so I don't think that I will add an aftermarket cargo mat on top of it.
While commuting to work this morning on the freeway I really did notice a difference. I did not have to crank the radio way up and the voices and music were much clearer.
If you are looking for a real easy sound insulation solution I would recommend this product.

It did however, take me double the 30 second recommended install time, due to me flopping it in there upside down and then having to take it out and flip it over because I didn't read the instructions.

First drive to work this morning and I can tell you it makes a big difference. Those that say it doesn't must have some really frickn' loud exhausts.
It took the resonance away that the road puts through the rear hatch area (hatch floor, plastic) and the road noise from the tires is probably cut in half.
There's also a noticeable "quietness" inside the rear now that I never had before. I always had that "white noise" behind my head from all the noises coming from the rear hatch area. Now it sounds like the entire car is quieter.
It made such a difference I am no longer worried about putting dynamat or peel and seal in my car. I will however still do the peel and seal on the floor boards under the car because now that the rear is so much quiter I hear road noise from under the car... lol.
Overall, it's a great buy and I'm glad I bought mine!!

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.

It arrived packaged well. Easy install with a precise fit. I was able to use the rings and shade. I found it able to make a nice noise reduction on all surfaces around Little Rock including interstate and different road surfaces including concrete and asphalt.
I'm very happy with the product!

As it turns out there is no need to do so because the noise reduction is truly dramatic. This kit is a "must have" for all but deaf C7 owners. I had a '14 Z51 which had hellacious tire noise. I was exhausted after driving it for 3-4 hours. The '15 Z06 was significantly quieter and rides more smoothly....think Chevy vehicle engineers softened the suspension bushings. Seems to be well known that the '15 is a quieter car. Just can't believe how such a relatively inexpensive and easily installed kit can be so effective. I could now drive the car across country....yes, it's that good.

So bottom line: I'd recommend(your hearing my vary) .
I can't say it's equal to the kits that require full interior dis-assembly since I didn't do that, but I definitely feel there is value in the product. If you are in Southern Calif and want to try in your car, come by and we'll throw it in and you can hear for yourself. Or just take my car for a test drive.

Started the car in my garage and could hardly hear the exhaust with the windows up. Backed it outside ( a lot of snow here now ) and tried the same thing, windows down ,windows up. I will not get to take the Z06 out until spring, but I can tell you that there is a substantial difference in the noise factor just sitting in the car and listening to it run.
Great product. Can't wait to do a more extensive test in the spring, but initially this seems to be a great product !!
Many thanks,
Dave

Super easy install - drop in and forget it. I have a coupe.
Big rear mat had the slits for rings.
Put my Stingray logo rear carpet on top of the mat and also put the mats behind the seats.
I can tell a difference in noise ; can hear the radio better and believe a long cruise will be far more pleasant.

I did notice the action of the Bose audio pilot (auto volume compensation) is much more noticeable now and I turned it off.

…… is it worth the $230?? to me yeah, because i am lazy don't want to pull all the carpet out.... so with that being said, money well spent to me

I'm not an engineer, but I have soundproofed a few cars over the years. In the past I would typically use one of the standard butyl + aluminum products like dynamat, then in the trunk or other flat areas I would install a layer of thin foam. Usually pretty good and noticeable results.
I'm working on my Corvette right now. I did some research and found Cascade Audio Engineering's website and read up on a bunch of alternate materials they offer. I ended up purchasing a product from a different supplier, Parts Express in OH, called Sonic Barrier MX-4, which combines the butyl & aluminum with an integral layer of foam so you put it all down as one layer and it can conform and stick to any surface.
I can't comment yet on the overall results, as I have the car torn down for some other parts to be installed like speakers, head unit, shifter, etc. I will be doing the behind the seat area and tunnel this weekend.
Just tapping with my fist on the rear areas as a quick before and after test you can tell that there is going to be a nice noise reduction. It's a very solid "thunk" sound now. I will be doing the doors as well. Here are a couple of pics of my progress so far, good luck with your potential project!
I've done a few C6's with the foil/bubble wrap insulation from HD/Lowe's. No before and after sound or heat measurements were made, but the results were satisfactory for myself and the other owners. About 1/4" thickness seems to be the maximum to be able to get the carpet back in without difficulty.
I've never done a vert, so I have no experience with the back end of those.
BTW, tires make a much bigger difference when you're dealing with sound. New ones are always quieter than old. My favorite C6 tires are Invos.
I put the duct insulation from Lowes in the Z06. Put in in the entire rear of the car, behind the seats, and all over the console. It did help with the noise somewhat, but helped tremendously with the heat in the console area. I am told that I also need to put it in the fender wells, as that is where a lot of the noise comes from. I have not done that as of yet.

Another sound insulation thread
Great product, does what Ed claims.
I have an 05 vert with borla stingers and love the sound. But on the interstate and highway speeds, the car is just kind of loud. Not just from the exhaust, but from road noise. So I bought the new "blockit' insolation kit sold here on the forum. Not the kind that requires you to remove the carpet or anything. Just put two pads behind the seats and one pad in you truck, or cargo area for a coupe. I drove my car at 70+ MPH for a good ways last night and WOW!!! Much smoother and peacefull sound. The stereo sounded better and the car just seems so much quieter in the cab area. I have had a C6 coupe and now have a C6 vert, and I promise you, this thing works! Just wanted to shout out a nice mod.
