Given the exhaust drone and reverb noise kickback from an Alta catback exhaust installation I was looking for a solution to help quiet the ride (the girlfriend complained on a recent cross country trip as well).

After a few discussions with some friends / enthusiasts I decided on Dynamat and had it installed on my R56 '07 MCS. Huge difference!

There seems to be a lot of dealers / installers who work with Dynamat so if you're interested it might be a good solution and probably easy to find a vendor within your area.

Happy Motoring.

 

What part(s) of the car did they cover? Entire floor? Trunk area? Sure hope they didn't cover the airbag vents.

 

there are many cheaper and just as effective sound dampening materials on the market. Nothing necessarily wrong with dynamat but as far as value goes, they lose.

 

True - the whole trick with sound-damping material is just to add weight to the various panels to lower the resonant frequency. If two different brands weigh the same per square foot, they'll both be equally-effective in reducing noise.

One caveat, though - I would definitely go with one of the brands that has an aluminum liner on the non-adhesive side. It makes it *so* much easier to work with, especially if you're using a heat gun to help ease the installation.

 

if you search for FatMat, it seems to be a better bang for you buck then dynamat. It will make a big diffence on your vehicle. It is really very easy to install it is worth it as a DIY.

 

I used the FatMat before too. Easy to work with and does its job well to silence the vehicle.

 

Speedin Bob. Yes, trunk area, wheel wells. They can also be used in headliners, 3rd door clubman, etc. I have the dual sunroof option so no headliner for me. Additionally, I have the delete a seat kit so it was a little easier to maneuver the dynamat into the crevices, tight spots.

Absolutely no effect on the airbags.

Yes, dynamat does have the foil backing and is easy to use.

 

Did you have to insulate the area under the rear seats as well? Which areas make the most difference in your opinion?

 

Gentle bump since I'm also curious about the answer...

I started a thread in the Navigation & Audio folder (1st Gen) since I have a 2006 Justacooper, but I figured the answers would pretty much be the same:

The rear seat does a fairly good job of reducing noise. Unless you remove the rear seat (as I did), it would be one of the last places I would add dampening. I would try to cover the vertical area just below the front of the rear seat.

 

ive noticed that a lot of the exhaust noise comes from the air vents right below the hatch door. Ive practically covered the whole back end of the car with edead but thats where all the noise is coming from. Im thinking of getting some fiberglass insulation and stuffing it in the vent area since air still needs to be able to move.

any other ideas?

 

I used FatMat in the rear section of my GP but I also notice a lot of noise coming through the two rear air vents. I put some high density foam (actually pipe wrap because it curved over the vents nicely) over each vent which cut out the noise. However, I do notice that it gets a little more stuffy in the car and I end up using a higher fan speed sometimes.

 

i'll have to try that...

BTW try not to break any clips they cost a GRIP!!

the black clips that hold the carpet down are 2.15 a PIECE at the dealer. Color me crazy but that is just absurd for such a small piece of plastic.
