Hi

Now just have to rip the roof lining out and Dynamat that as well!!!

Reckon it would make a huge difference to noise

Yeah big difference on the noise front, makes me want to line the firewall on the inside of the vehicle (I reckon a good % of the noise comes from there). But first stop is the roof lining, then the doors, and see how we're traveling then.
For anyone who is looking at doing a Dynamat job, what you see here is one whole box!!! I've started just infront of the rear seats, and go right up under the dash. I need to go back and do under the rear seats at a later time.

I am waiting on a shipment from overseas to finish the job as the local prices are nuts..

While you're at it I would do the doors too. Also makes a huge improvement to your speakers.

[Bloodyaussie]

I can do doors later but the firewall was the main priority. ..

Really waiting to see what the quality is like on the stuff from overseas..

Your biggest worry is buying the bitumen based stuff.
It melts away with low heats and makes just a big mess..
What about the stuff I tagged in the sound deadening thread.
It's exactly the same as dynamat but with out the brand name, nor price tag...
Ask FNQGU.. He bought genuine and the left over stuff I had and can confirm it's the same..

[Throbbinhood]

That looks like a lot of work! how'd you go with it?

[v502]

Nicely Done. On my list for sure.

[TazManiac]

That would make a huge difference to noise levels in the cabin. Well worth the effort. Thanks for the photos.

As Winnie says, don't forget those door skins. Huge amount of noise from the road comes that way, plus the difference to your speaker sound is unreal.

I just did my old mq (noisy old diesel beast) with some ebay butyl based material.

Did the door skins and rear side panel skins and also the tailgate skin. Those were the easy ones and just tapping the sheet metal on the outside after the job and all the tinny drum sounds are gone. The whole point of the sound deadening material is really to absorb the energy/resonance in the metal and that's what the butyl material is there for.

I then did the front floor areas, transmission hump and up as high as I could go on the firewall, without stripping out all the front dash (way too much work for me to bother, though it would have been nice to do that). I did under the front seats and just behind them as well.

On the test drives after the job, it is definitely noticeable that you can talk to the fellow passenger at a normal voice level and easily hear them. Quite an improvement for about $200 of material and several hours of work.

What I will have to do next (next time I'm back in oz) is put some material on the bonnet skin, since lots of engine noise goes through that metal and straight through the glass into the cab. I'll have to source some higher temp material that works in the engine bay. The old nissan 'mat' based liner that is presently there is a little old and could do with modernisation. I'd also like to use some high temp material on the engine side of the firewall, plenty of room to fit some there in the old school mq and that should help a lot too.

Anyhow, certainly a worthwhile exercise.

cheers,
george.
