Installed FatMat on '05 STi...WOW!

[Brahmzy]

I installed some FatMat (wannbe DynaMat) in all 4 doors, under back seat, rear shock towers, whole trunk. WOW! What a difference! That familiar Jumbo Jet-landing-on the-runway sound is a whole lot quieter!

I can't say it enough how happy I am after doing this.

I think I only added about 10-15 lbs at the VERY most. I took out my jack and spare a while ago so it more than equaled out.

$49 on ebay for 36 sq ft. and I still have 2 sheets left. I might do the firewall next.

Make sure you cover the grommet over the gas pedal. It's a large source of unwanted sound, and deadening the firewall will most definately help reduce cabin noise. Thank you for using sound deadener without hesitation. The key is to use just a little more than you really need. Most people end up not using enough, then blaming the product for poor results. Good job.

we are getting ready to sound-proof our 05 wrx for our upcoming soundsystem on the wrx.
ej20fan suggested to do this he REALLY knows the wrx, check his system out if you go there, (soundwaves) we are doing a full blown system based on ej20fans ideas and suggestions.
we will let you all know how it goes!!!!

its sound deadening material, which means it will keep outside noises outside the car, and it will also make your sound system inside sound much better because its staying inside the car. so yeah it will quiet up road and engine noises inside the car.
