Dyna Mat Update!!!

[Mikey21]

In a previous thread Dyna Mat not for exhaust noise. I mentioned how Dyna Mat or any acoustical matting is not designed for eliminating exhaust noise. I explained how I matted the entire back half of my car with no noticable results. Well some of you convinced me that I didn't go far enough with my sound proofing.

So taking in all of this good advice I finished the job of matting my entire car!

Trunk Floor = 1 - Layer of Dyna Mat Extreme, 1 - Layer BQuiet Ultimate, 1 - Layer BQuiet Composite Foam Mat.
Trunk Sides and Lid = 1 - Layer Dyna Mat Extreme, 3 Coats of Sound Deadening spray on all in accessable areas.
Entire floor including under the seats and fire wall = 1 - Layer Dyna Mat Extreme, 1 - Layer BQuiet Ultimate, 1 - Layer BQuiet Composite Foam Mat.
Doors = 1 - Layer BQuiet Ultimate on outer skin, 1 - Layer BQuiet Extreme on inner panel.
Rear Deck, Pillars and Kick Panels = 1 - Layer Dyna Mat Exteme.

Here's some pic's




Well it was hard work and very expensive! But I tell you what!!! My OEM stereo flat out rocks! The sound quality is thru the roof, and the bass is like there's a 12" sub in the trunk running on a 500 watt amp. It's a real sense of acomplishment when I listen to my stereo now.



Oh, by the way. My exhaust is still loud and annoying as hell! So save your money unless you're looking to upgrade the sound of your stereo.

haha looks good...too bad about the TN advice though

[sk8chip98]

did you try to put another resonator on your exhaust? how new is your exhaust? over time carbon will build up in it and help to mellow it out a little bit. good luck with
it....

[Super Kaioken]

lol dang you did mat down the entire car and i bet your car now's like a ......

audio enhanced car =O

[BlueFusion6851]

so shiney
i'd do that just for shits and giggles

[Terriyaki]

wow how much was all of that, looks like alot lol. nice ^_^

[Knailgun]

labor of love there......I roadkilled my car (stinger version of dynamat) and did it with the aresol...I was lazy

[emiliorescigno]

I am inspired! I think I'm going to do the back half of my car(s) for the sake of sound quality, sorry about your exhaust not being any quieter though.

[Eye8Pussies]

lol...that's a lot of dynamat....


you don't need sound deadening when you have lexus

[whocares04]

u all forgot to mention how much more weight he added to his car

It's a 2004 Camry so it's new. As far as another resonator it's a possibility but I actually love the sound of my car. I just want to keep most of that lovely sound outside where it belongs.

The total cost of the dampening materials was around $1,100. Though I have quite a bit of left overs.

The closest guesstimate I can come up with is around 90 lbs.

Dyna Extreme & BQuiet Ultimate = 130 sq. ft. @ .35 lbs. per sq. ft. = 45.5 lbs.
BQuiet Extreme = 40 sq. ft. @ .30 lbs. per sq. ft. = 12 lbs.
BQuiet Composite Foam Pads = 32 sq. ft. @ 1 lb. per sq. ft. = 32 lbs.

Total of 89.5 lbs.

Which is less than a tank full of gas or a passenger. I know that every 100 lbs. equals about .10 at the end of the 1/4 mile but at least my bass will be pounding the remaining 99% of the time I'm just cruising around.

The sound dampening didn't help with my exhaust sounds but I'm totally rewarded by the improvement of my OEM stereo. Nobody believes it's stock once they hear my bass kickin.

My wifes previous car before her 2003 Camry SE was a 1998 Toyota Rav4 and I paid a car audio shop $800 to Dyna Mat the side body panels. It improved the sound quality but I wasn't happy with quality of the install. So for around the same amount of money I've got 3 times the sound deadening material with a very clean install, and a killer sound quality resulting from it.

Holy Shit 1100 bucks?!?!?!?!! Did you look into the Prices of Raammat and Ensolite? Probably would have been less than half.

[terrastrife]

what is your exhaust piping made of?

I looked at Raammat but they didn't list the ASTM test results for decibel reductions. I only considered companies that listed the ASTM test results. From there I decided on the cost in relation to the sound deadening. B-Quiet Ultimate in the 50 sq. ft. roll won (minimum 3 rolls for price break). I bought the Dyna Mat cause I thought of it at the last second and bought it locally at a rip off price. I bought the B-Quiet when I decided to finish sound proofing the rest of my car.

Also $1,100 is what I spent on all of the materials. I have about 100+ sq. ft. left over of the B-Quiet matting and a 13.5 sq. ft. roll of the composite foam mat. That's approx. $300 of left over material.

I guess steel??? It's OEM except for my muffler which I believe is stainless.
