Angry Please God help me with insulation advise!

Having a 1997 Impreza L means 3 things, smaller engine, drums in the rear and NO INSULATION IN THE DAMN CAR!
I've had my exhaust (added a Resonator a few months ago which did very little) on for a while now and it's finally driving me nuts, what can I do to cut down the sound in the interior?
I was thinking of using thick carpet padding from Home Depot and line the floor, side panels and door panels, but I don't know if this will be worth my time.
Can anyone else help me here, I want to keep my exhaust, but I also want to be able to hear my passengers!
Thank you!

Bry.

Brys,

I'd check over in the audio forum - the guys over there talk about sound deadning quite a bit. I think the popular brand seems to be Dynomat, but I don't know about any others.

Ya, Dynomat is good for speakers and keeping sound in, but I want to keep sound out.
Plus it's expensive and I'm cheap
Thanx though
Bry.

Angry I understand

I have a 1997 OBS w/ exhaust and Falken Tires. Once you hit 30 miles an hour and up you cannot even hear yourself think. The most annoying is the tires. They whine and roar to the point when I take a ride further than 20 miles my head hurts so bad that I cannot even see.

I have the Dynomat in the doors for my speakers, but it does nothing for outside noise because it mainly comes in through the floor and cheaply padded firewall.

Good Luck and let me know if you find anything.

Put the dynomat on the floor and firewall. Put it in the trunk too. In my old RS the spare tire well used to look like a giant subwoofer when my stereo was on because it was so thin and it vibrated so much.
Floor of cabin, floor of trunk.
Doors
Trunk lid
Sides and rear of trunk
Behind the back seat.
Roof
That should take care of a lot of noise. There is another company that makes sound deadening material similar to dynomat, but cheaper. Search in the audio forum.

I'm gonna try the carpet padding first cause it's $6 for a 8ft by 4ft piece and pretty thick.
I have new upolstery coming in this week so my seats will be out and I'm putting down more black carpet to cover the nasty beige stuff in there now.
Since the Seats will be out, I'll just gut the bitch, spray some adhesive glue to the back of the panels and onto the actual inside walls and line them with the padding, line the floors with it and cover with the new carpet, hopefully that'll do it.
If not I'm gonna sell the exhaust to someone with an RS who actually has some insulation in their cars.

Ever flown in a helicopter?

Well, the pilot communicates with the passangers via headsets, you should consider getting those instead.

check this site www.b-quiet.com they sell sound deadening stuff just like dynamat at a fraction of the cost

Do your floors real good and doors good as well but focus mainly on the floor especially near the firewall. the doors will help a lot as well... U can even do the roof if u want

Default From experience...

www.dynamat.com (fraction of the cost... fraction of the product) they have patents for a reason...

Dynaliner xtreme for the floor (no stickey) about 3 boxes
(one for the front seats... one for the tran tunnel...one for behind and under the front seats)
dynamat xtreme under the rear seats and next to the rear seats...(side panel)(2 door kits)

then i also did the entire trunk.... i have zero road noise... a little exhaust hum but very pleasant..

even concrete highways are quite...

did my entire doors too... and hoodliner (saves the paint)

dynaliner xtreme ways almost nothing... xtreme is a little heavy...
didnt notice any slowing down though...

had it for 4 years now... dynamated for 2...

and will do it on my next car for sure

(ps lowering the soundfloor also increases sound quality...of you audio system... )

Not a fraction of the Product!

At www.b-quiet.com they have a mat that is called brown bread.
There was a review done of all the different sound deadeners and Brown Bread came out over Dynamat.
