I heard that if you dynamat the car it will reduce the road noise / tire noise. Has anybody done this? thoughts?

I'm sure it will, but I don't find the road or tire noise bad in the GS at all and I have the F Sport model. If I wanted that level of isolation I would have gone with the LS.

Never heard of dynamat. Got a link where I can read about the process?

I think the car is super quiet and I have the FSport also. But if you get the dynamat done, I could only imagine that it would cost a grip...since they have to take out everything and put it all back. This car has so many wires I wouldn't even try it. If you do get it done, please post back what the cost was (I would be curious).

You can try the spray on stuff like "Second Skin Spectrum" or something like that (not sure if this could be installed under the body of the car though. But that would mean you have to take apart the undercarriage.

If you do anything Dynamat is the best, especially on a high end car like your GS...

Just my $0.02

Those stuff will make your GS heavier. Unless you want your gas mileage suffer and tear out your new interior to put it on:

Very cool! Thanks for the info. I'll look into this some more. Probably won't do anything soon, but it's on my list. I bet it wouldn't add that much weight. I'm apprehensive about tearing the car apart, but a good shop ought to be able to do it without screwing things up.

It's not quite that simple. You'll learn more here:

Previously I've used vibration damper, foam, and MLV (adding almost 1/2 in of thickness on top of the car's skin) on the entire car (Corvette). And I was not able to appreciate much noise reduction. My sound system did improved significantly. Especially the bass response.

Also I found dynamat extremely difficult to work with. I prefer the CLD tiles, much thicker and way easier to apply.
