Interior noise is a big issue for me, since my 'Stang is my daily driver. I like to be able to hear my stereo and <gasp> actually have conversations in my car while driving.

For starters, I lined my trunk with some leftover carpet and then topped it with a storm blanket. It helped some and actually doesn't look bad, but I still haven't achieved the results I want. I think much of the noise comes up through the back floorboard.

So my question is: Has anyone had success in soundproofing the interior? How and with what materials?

I don't think it's possible...Mustangs are just too leaky.

You are never going to be able to get it to be 100% soundproof, but ther are a few things you can do to help. Go to a carpet store and get carpet padding, lots of it, and get lots of dynamat. Pull up all the carpet in the interior, take out the back seat, and take off the door panels. Put dynamat ( I use dynamat extreme) over everything you can, then put carpet padding over that. Then just do the same thing in the trunk, line everything you can with dynamat and then cover with carpet padding. Thats about as soundproof as you are gonna get. Good luck.

So you dont even wanna hear the exhaust??? Thats crazy!!! But whatever floats your boat. Does Dynamat do anything like this? The new ford trucks are supposedly "sound proof" on the inside, so find someone that owns one and look around.

Maybe you just need a hearing aid

I dont have a problem hearing passengers screaming "I CHANGE MY MIND!" with the top down, radio blasting and exhaust roaring at 130mph


Alot of noise comes through the rear seat area...Dynamat in the dip where the seats sit and in the general back area will do away with alot. A layer behind the dash along the firewall will get rid of most of the other engine hum..and around the shifter/console... yea, you're gonna need alot.

Wow, I have a prochamber/flows and no soundproofing on my daily driver and complain about it being SO quiet inside the cabin, no prob having a conversation or anything. Back on topic, dynamat.... won't be 100% soundproof but hey it's a car not a recording studio.

Ford did make a couple of changes for the 2004 model in the noise department.

Sound deadening..

You can do a decent job bringing down the decibles (with the windows up, you can always lower them to better hear the roar of the V-8 ), but you need to work at it. If you want to do a decent job of it, it can be a bit of a pain. You really need to pull out the seats (all of them) get under the carpet, pull out the interior panels (not all that hard, just annoying..) in the passenger compartment AND the trunk. You can do a decent job without adding heaps of weight (some of the sound deadening material weighs near nothing but some of the cheaper stuff weighs a ton). I used Cascade VBLOK and Brown Bread (dynamat clone) and careful use of aerosol foam insulation.

When I put my stereo in, I ripped out all of the heavy craptastic factory amp/speaker setup and I made the new subwoofer and Amp / Crossover rack easily removable. When I want to go to the track, I pop a few connectors and lift out most of the weight of my system. I figure all the soundproofing material I added still is far lighter than the old stereo I yanked out. You can see some photo's (in no particular order unfortunately) of how I did it at Stereo install .

thanks for the info, guys. I don't need it to be 100% soundproof, and I figure if I wanna hear the exhaust I can roll down the windows... "Dynamat" was the info I was looking for, you guys are great!

I have the brown bread from b-quiet

It's like dynamat, but cheaper. It has the sticky bottom with silver top. It cost me $99 for 35 sq. Ft.


It cut the noise down a lot, and the drone is only annoying at 2K RPM.

Here's a link to it. http://www.b-quiet.com/brownbread.html

If anyone is having problems with the noise coming from their tranny, check out my gaskets. They will pretty much eliminate all the gear whine and vibration coming from the transmission that everyone experiences after installing an aftermarket shifter. Ive sold quite a few sets to members of this board and they can vouch for me. Later guys.
