By adding around 30 pounds in sound deadeding material to all 4 doors, rear seat (isolate the trunk from the cabin) and roof I transformed my Evo driving experience ten folds in addition to improving my audio system in the process as well. No more rattles, less road noise and clearer sound coming out my front speakers.

I run a tanabe exhaust which is really nice with an ER cutout for mean power when I need it. Most of the added weight was in the rear seat area including the floor (fuel tank). I followed Don's tip http://www.sounddeadenershowdown.com/ and used his material for most of my work with the addition of the dynamat door kit for the front doors. I came up with zero gain in the roof by removing the handles. For track days, by removing the back seat I get rid of more than half the added weight so it's a win a win for me. I know most people dread the notion of adding even a pound of weight but outside of an all out race car, the benefits far outweight the cons of adding material for a quieter and more pleasant ride.

 

Do you have any pictures of the work you did? Sounds like a good project if your looking to make the evo more people friendly.

 

this; i wanna see installed work!

Also, the sound deadener showdown stuff in the doors would have been better than dynamat IMO

 

I don't have pictures

It's very similar to what the website shows for each part of the car. I used CLD tiles to treat the outer portion of the doors; three for the front and two for the back doors. I then used the dynamat kit for both doors covering the entire inner pannel up to the mounting holes. For the back doors, I did used the MLV stuff........it's a pound per square feet. I used the inner door panel to cut a mold and then bounded it to the door using the metal holder thing and 3M metalic looking tape.

For the back seat I basically used the MLV as a cover against the rear portion (the one looking at the trunk). Used some velcro tape to hold it in place. I also used MLV over the entire fuel tank and wheel well. Also treated the rear deck with dynamat left overs.

For the roof I used 6 CLD tiles and a layer of 3m insulate.......simlar to what you see here:

Like I said, the driving experience it's so nice that even the wife who hates the Evo likes to ride in it now and listen to her music. (I have a set up with amp, front speakers and small sub under the seat)

To be honest, it's easy work......just take your time but the material and instructions available makes it a breeze.

 

mind asking how much you paid + shipping? and how many sq.ft of MLV and number of CLD tiles you ordered?

don's pricing is good but i'm curious what the shipping costs are like

 

I pay 207 shipped!

It include 25 CLD tiles, 18 ft2 of MLV, and 20 ft2 3m thinsulate acoustic.

If you want to use the mlv for the front doors instead of dynamat, then 24 ft2 should be enough.
