Dynamat worth it ? - quoted $450 from audio shop

SouthArk370Z · 12-11-2014, 12:01 PM

I used some GTMat material (don't remember which flavor) that did a good job but I just wanted to get rid of some of the road noise and wasn't trying for a really quiet cabin.

I had my favorite body shop R&R the interior panels and I installed the material myself. As per Chuck33079, it's not a hard job if you have a good cutter and a small roller.

You'll want a louder exhaust once you install the sound-deadening.

I had a local audio shop do this for me a few months ago. They used something other than Dynamat and IIRC wound up using more than the equivalent of one roll just in the rear (more in the doors, of course). I had no rattling issues prior to that. My bill ran more than your estimate, but is probably largely due to a smaller market with essentially no competition. I didn't watch the install, but they did keep the car overnight due to the time involved.

She sounds like a keeper! It was definitely worth it to me just to quieten the road noise. I'm very pleased with the results.

This sounds right to me. If I had a younger back, I probably would have tried to tackle this one myself.

I also found this to be true, but it sounds like OP has already taken this step.

I did mine myself. Not hard, but be prepared to spend 4-5 hours crouched in the back. It does help, but don't expect luxury car quiet. I can't imagine mine w/o it + my FI exhaust & cats. It would be deafening without the dynamat.
