    I think in this post someone is referring to shiny stuff as dynamat....?
    http://www.corvetteforum.com and do a search on 'dynamat'
    I think you will fing it is VERY popular in the vette community.
    (I think they had a member discount happening last year)
    No personal experience - sorry.

    my personal opinion is that the regualr foam sound deadner does as good of job if not better at a cheaper price. Dynomat is pretty spendy... probably why the vette guys use it LOL [​IMG]

    I have Dynomat on my floors, doors, rear panels, and cab roof....total of about $200...makes all the difference in the world....I can still hear the exhaust when I romp it, but just driving, it's really quiet...I run headers, Dynomax, hiflo cats, and 2 1/2 pipes.....Alpine/Fosgate....6 Denon's in dash, kickpanels, rear panels, and a 12" sub....400W....the matting seemed to help the stereo more than anything else....I just keep vibrating the dome light covers off, and those little wing windows on my sliding glass vibrate when I stand still.....hope this helps some...JD

    I'm at 10th and Plum....10 miles from nowhere, and Plum out in the sticks....Stuck?...Hell no..I still got some gas left..

    Not me, my vette is TOO quiet. Planning on doing something nasty to the exhaust when I am done (HA) with the Blazer project.

    I would think using liner and then the foam mating would work just as well. I know the liner is like $100, but at least it helps to rust proof it......the dynomat seems pricy for what it does...but that's just me.....

    I used to install car stereos fulltime and have used my fair share of dynamat. I also have a box full of the stuff in my garage waiting to be put in the Blazer. If it is installed correctly, which is a pretty time consuming process, I've never seen anything do a better job. But it does take a lot of money. If you don't mind spending a C-note or two on it, you'll notice a big difference...but if you want to spend less, then the other alternatives are OK. If you do decide to buy some dynamat PLEASE get the dynamat Extreme and not the original...its only a little bit more pricey but over 4 times more effective. Also might want to check Ebay for a "generic" dynamat...I've seen it on there alot for pretty cheap prices.

    I helped my friend do his car with Dynamat. It is heavy. I was going to use it in my car but wanted to keep the weight down- it was a street/strip car. If you don't care about weight and are keeping your carpet/trim it is great. It also seems to help isolate the driver from vibrations and makes the radio sound better. I haven't tried the Extreme, but if it is that much better for a slight increase in price it sounds like a great value.
