Sound Insulation
I'm debating on insulating the Z so I can talk on my cell phone and to the passenger(gf). After searching for the past few days it looks like the options are between Dynamat Fatmat and Crazycowboy. For ease of insulation Crazycowboy wins hands down because it is pre-cut. How do the two compare for reducing the sound? I am curious which product is denser. I know a 100' roll of dynamat is 23 pounds but will be much less once it is cut and installed. Crazycowboy only weighs 6 pounds. These are both ~45mil thick so I'm guessing that the Dynamat is denser and therefore would provide for more dampening.
Any opinions?

I have Crazyboy's setup and I am installing it this winter. I am going to upgrade my stereo as well. I have decided to use Dynamat inthe doors, console, and over the wheel wells in the rear hatch alond with the kit by Crazyboy. I am not concerned with the weight. Dynamat is much denser and I have used it before. It is great. If you look at many custom cars, in fact many on tv, they use Dynamat Extreme. I am looking forward to it, I think the result will be acceptable. Good luck, I know I didn't really help you as my system is not in yet, but just an opinion.

Quiet Car
Just another option that you may want to consider. I read today as a matter of fact from one of our members that he used both the Quiet Car solution and the pre-cut insulation from Exotic Corvette. He indicated he was very pleased with the result.
Below is an excerpt from the home page of Quiet Car:
Remember high school science? Mats are the “old school” technology - they merely try to mask the noise by using mass. QuietCar converts the kinetic (noise) energy into heat energy. You can theoretically measure it, but it’s less than 0.1 degree Fahrenheit. By absorbing vehicle body vibration, engine and road noise can be reduced by up to 20dB – that’s an astonishing 75% of the noise - depending on vehicle and application.
QuietCar is easily applied on any surface by brush, roller, or sprayed on with a spray-gun (sold here) for use with air compressors or with an airless paint sprayer. The advanced viscoelastic properties allow the coating to absorb noise and vibration. The more you apply (underside, inside under carpets, wheel wells, engine compartment walls, trunk etc.), and the thicker you apply, the more noise will be absorbed. Lab testing shows this breakthrough technology reduces more noise than mats such as Dynamat...and is less expensive and takes less time to apply.
QuietCar is manufactured by Quiet Solution, Inc. and exceeds all fire standards for use in motor vehicles including FMVSS302.
For an Average SUV
Cost Noise Reduction # of Hours to Apply
Quiet Car $300-$500 60-90% less than 4
Dynamate $600-1000 30-50% 12+
So, if you’re thinking of using a product like Dynamat, why settle for old-school stuff? Use QuietCar instead. Thousands of satisfied customers are already using QuietCar. Isn't it time you did?

I also looked at the Quietcar but wasn't sure if it was all they were claiming it was. Anyone else have any experience with Quietcar? Know how many gallons it will take and or how much a single gallon weighs when dry? I remember reading that post yesterday so I'm going to try to find is and as him. Cost for 5 gallons is the same as Crazycowboy's kit. Now you got me thinking about going this route.

Quiet car talks about putting it on the metal surfaces.
But in the vette, your dealing with a lot of plastic. Not really clear it there are any application issues here.
Doe anyone know the color of this application?

dynamat is a vibration dampener, not a sound deadener.
If you want a sound deadener, this is what you should look for:

I used the insluation that was purchased from lowes and home depot (frost-king). This is not worth the time or money. I have done the entire rear, interior, and wheel wells. This did drop the noise some. It also helped lower the heat inside (I'm north of Houston).
I have used some of the b-quiet porducts (b quiet extreme) in my 2002 F 250 Crew Cab SD. This made my truck as quiet as my wife's Lexus. There was/ is no smell from it either in the winter or in the summer. I have seen temps as high as 155 ( I keep an a/c thermometer inside to monitor my a/c register temp) inside my truck when it is parked in an asphalt parking lot in Houston and Austin. I have had NO PROBLEMS with this stuff. I used just under 2 rolls for the complete interior of my truck. I think that I can get away with 1 roll in the Vette but I am going to order two just in case.
I now have to pull all of the other stuff out and replace. I hope it comes off well. Here is a link to a page where someone put it in their vert. http://www.b-quiet.com/corvette.html Heused the brown bread but they no longer make bb and they recomend b-q extreme as comprable.
Have fun and do not be cheap. I decided to try the cheaper route and you get what you pay for.

I have a 2003 Z06 in which I installed insulation throughout the interior. Bought it from Exotic Corvette. It's precut and easy to do. Then I purchased $200 worth of B-Quite sound foam over the insulation. I now can compare my Z06's interior noise with that of my wife's Lexus. And it gives the car a more compact feel. Best of Mod I've done. ( I also have the trunk partion).
