I am no expert, but I believe WHERE you do your sound deadening is as or more important than the materials you use... as stated in previous post the wheel wells are VERY important to eliminating unwanted noise in your C5 
For what it's worth I used Frost King from Lowes and am satisfied with the results... I have used TONS of Dynamat on other projects and it's a great product...

Around 8 years ago, I used a layer of Damplifier Pro followed by a layer of OverKill Pro (products by SecondSkin Audio) and I have been very satisfied with the results. For this to be effective, you need to cover the entire interior: cargo area, footwell, torque tunnel, bulkhead, and doors. With removal of all panel pieces and seats, sound deadening material installation (e.g. cutting all pieces perfectly to size and application), and then re-installation of panel pieces and seats, it as a full 2 day job.

You can get the precut(and labeled) sound deadener kits from Vettenuts. Being mine is a C5Z and Borla straight pipes I will be buying that with a real partition. Mine came with a silly foam one that serves no purpose.

Check out the Blockit "Quick & Quiet". It takes about 60 seconds to install (less if you want to take it out). There is no adhesive. Its precut and lays over your existing factory carpet.
You can put an aftermarket rug over it if you want.
This is NOT a single layered mat.
The BLOCKIT is a unique 4 layer combination of real acoustical soundproofing which measures 1" thick!
It's patent pending design absorbs and suppresses unpleasant sounds that leak into your C5s cabin.
Just place it in!
Comes as a 3 piece kit. One for the cargo area and piece for behind each seat.

Then there's DeadMat. which is a lightweight but extremely effective at damping & blocking unwanted noise & Vibrations! Its weight to performance ratio is amazing. Very durable. Won’t rip, tear or break down overtime! Simple peel and stick application. Apply to any make or model where its needed!

Doors
Under The Seat

Blockit & DeadMat are actual Acoustical materials. ALL products are manufactured under strict ISO regulations! Made in the USA! Even the raw materials are from the USA!!
Below are some comments pulled from this forum about the Blockit...
I installed the 3 piece system and finally got a chance to do a test drive this evening. I was very pleasantly surprised how well it worked as the improvement was immediately noticeable. The noise level inside the cabin was reduced and I had to lower the radio volume since it was so much easier to hear. I can still hear the nice sound of the engine & exhaust, but without the annoying road noises. Very pleased with this purchase.
I installed the Blockit sound insulation mat and the behind the seat panels this weekend and I am very impressed. The mat just goes in the hatch area and the fit is excellent. I installed the two panels that go behind the seats behind the carpet. The carpet in that area is not tacked down so it is easy to do.
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.

I just put one in my '05 coupe. The difference in interior sound was instantly noticable. After cranking it up I had to put the window down a little to make sure the engine was running OK.
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.

Great product, does what Ed claims.
I got mine yesterday and installed it last night.
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!!

To start with, I am not a vender and do not sell these things, but WOW! What a difference.
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.

Just wanted to shout out a nice mod.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.

Having had Blockit in my Z06 - I thought it did a great job reducing noise so I added it to the C7 - Z51.
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!

Installed on my C7 Z06. TRANSFORMATIONAL! The reduction in tire noise is astonishing. Being an engineer I had planned to use my laboratory dB meter to measure noise levels with and without the TKO Blockit kit. 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.
Well, I had a chance to test drive my car on some roads that previously had some serious tire noise due to the road conditions. For the ease of installation and simpleness of the product; I'm very pleased with the it. I was able to lower my radio volume from where it used to be, and hold conversations without raising my voice. In fact I am now aware of other noises that I hadn't previously heard.
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.

Received my set of sound deadeners yesterday and promptly installed them in about 10 minutes.
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

Just got my Blockit mats today and did a roadtest on the concrete I16 around Savannah and a couple miles on local black top.
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 have the Blockit mats. My wife can hear like you wouldn't believe. She is the perfect test for these. She stated to me that there was a significant difference in sound reduction. That's good enough for me. I thought there was a difference too, but I didn't want to rule out wishful thinking on my part so I had her listen before and after.
I put it in my 2016 Z06 last week and the difference is very noticeable. Less tire noise, radio volume setting is lower now and much more enjoyable. As another poster noted the exhaust sound now stands out more; my Z06 exhaust is normally set to track mode.
I did notice the action of the Bose audio pilot (auto volume compensation) is much more noticeable now and I turned it off.
