Car audio, DYNAMAT cost?

[jsmithepa]

Wanna quieten my 2010 Civic Coupe, the dang thing clocks in at 80 db @55mph. Doesn't have to be dynamat, any modern affordable but effective insulation will do.

Anybody done this lately and cost? (U.S. don't want to D.I.Y. will take me forever)

You pretty much have to take the interior out of the car to apply the damping material so it's very labor intensive. You would have to check out local auto sound shops to see that they charge for that. Some use sheets like Dynamat and some use spray on products.
Depending on where the noise is coming from it might not be effective. I had a Borla exhaust on a WRX and no amount of damping material would do much. This link might help
