ok I investigated where the worst noise was coming from, then took the advise and wrapped the kids in dynamat , I must say they were reluctant but its certainly quieter in the car now. Grin Grin Thumb

Sound deadening? In a 911 ? what

I must be in the minority who actually like the road noise Smile

All that dynamat must weigh a fair bit too.


I though this would be a thread about removing sound proofing around the rear seats to get more induction noise into the cabin



I hear Nissan Leafs are really quiet






Its it leafs or leaves?


Grin

I would've bought a nice jag or Bentley if I wanted little road noise, not a Porsche Smile and all that added weight Hand

Each to their own I suppose.


You like Tyre roar nooo nooo nooo


Cant say ive noticed tyre noise, what tyres have you got? PSE and h&s x pipe all i hear is the engine or the bose

Hi Guys,

I’ve done myself just the doors so far. And ive used flash band from B&Q It’s very similar stuff just bit thinner so you need to apply few layers. But much cheaper.
The downside of that is that flash band is burning as hell so potentially you building yourself a death trap.

Not sure about dynamatte, but I suspect the same as all those materials are made from bitumine anyway.

Another issue is that bitumine materials do the job when is worm, below some temperatures they getting hard and stiff loosing it acoustic properties.
