Alex,
I used about 75 sq ft of butyl mat and 10 sq ft of acoustic mat, I plan to lay down 12 more ft of acoustic mat under the seats. I do not plan to do the firewall, cause... frankly my engine sounds nice.
Total cost was $381 USD shipped. $342 USD just for the materials and $39 USD ship. Should be cheaper for you since the company is in Canada, and no customs.

Thanks Chris. This one of the nicest mods I'd like to do in the future.
How much time altogether have you already spend?

Alex,
I've got about 5 hrs in this, including breaks. The interior design just makes it so easy...

Totally off topic but,
This is my first thread on any forum ever! I hope I did not screw it up too bad.
I am totally amazed at the scope of knowledge and experience on this forum. I am on TTORA and TundraSolutions but this place is THE definitive place for 4th GEN 4Runner info. I have learned more in the last 2 months on this forum than in the 3 years of owning my truck. Thank to everybody here I now have a wish list a mile long, starting with SW sliders this month.

Default Soundproofing... the final chapter

Finished up the acoustical mat instal today. The mat I had was 36" x 54". I cut it in half legthwise, 18" x 54" and cut a 24" section from each long piece. I laid the 24" piece in the front footwell right up to the seat mount crossmember and the remaining 30" piece from the rear of the crossmember, under the front seat all the way to the rear seat hump. It fit perfectly.

Here is the front piece in the footwell with a cutout for the dead pedal. No need for this on the pass side.



Here is the middle, the 2 mats hugging the crossmember.



...and the back



Buttoned everything up, went for a quick drive. Road noise and tire noise is definitely muted. I noticed a nice reduction in noise from the CAI. Will get a better idea after my trip to Corpus Christi.

Chris, I'm watching this very close as I like what you've done. Post up your experience. If it's that good, I might do it as well.
P.S. ordered a sample from them, should get it by the end of next week.

Chris,
Now you have two layers on the floor. I know that more layers cuts more noise. How much difference does that last layer of acoustical mat make?

If you could only choose one layer or the other, which one provides the most improvement?

This is a well done thread, pics and all.

The last layer (acoustical decoupling mat) made a noticeable difference. It is specifically designed to absorb noise (foam) and to block noise (hvy vinyl layer). The sticky foil lined butyl mat that I laid down first is to stop/prevent unwanted metal panel resonance (improves audio performance), like pinching a cymbal with your fingers to stop it from vibrating.
So the last layer is the most important one.
As far as all the pics go, we all know that

Got the samples. Looking nice. Investigating what I might need and how much. Thank you Chris for the info.

Default Road test

Drove to Corpus christi yesterday (250 mi). Very noticeable decrease in road noise. Tire hum is still there but no longer obnoxious. On smooth parts of the interstate it was barely noticeable. Biggest benefit was stereo performance and casual conversation. I was able to set the volume at a comfortable level and still maintain clear conversation with all passengers. More noise reduction can be achieved with multiple layers of butyl mat. If you are going to do this in one sitting, plan on 6-8 hrs.
Overall I'm happy with this mod.

Evan, I used Ultimate.
It's the thicker/heavier of the two butyl mat products.

IIRC, Extreme is standard (45 mil), Ultimate is thickest (60 mil), and Brown Bread was the original formula and is now discontinued.
Dynamat is....... well Dynamat (overpriced).

Ok thanks

Any thoughts to how it would hold up to being soaked? When I had dynamat in my STi I recall it being a very dense rubber type compound and then a metallic on on top....not the type of thing that would absorb much water or need to be pulled up if it got wet.

Any thoughts on this? I emailed B-quiet but havent heard back from them.

This is exactly the same, a heavy butyl rubber compound with a foil layer. It won't absorb water.

Awesome..just ordered 100 sq/ft of butyl and 27 sq ft of acoustic mat.

Will hopefully add this to beneath the headliner at some point too....one of the things I like the least is all the wind noise from the rack and stuff on it.

Thanks

Would you mind saying how much the material costs were? I saw a $300+ cost early in this thread, but wondered if yours was similar.

Yea I have wanted to do it for a long time...having the interior out has just spurred me to actually get to it.

Of course I really want to do the headliner but thats evidently 3 hrs to get it out and 3 to put it back....so well see.

This is sick man! I really like what you did... Also, while you're working on that you can detail the car while you're at it....

Did you just cover what you could (basically the areas noted in the pictures) or you went and covered more that what the pictures show... I'm interested in doing this.
