In conclusion:
Im not going to lie, it feels like its been a slog. A job i really wanted to do but so glad i broke it down into segments. To do properly just takes so much time and you can easily get carried away just rushing it as its pretty laborious.
The boot and back end took me a week of evenings, the doors were a morning each and the interior cabin was a solid day. So you would need a good few days spare to do it. Of course im using my car in between time, so if you were to strip the car fully and run through the job, start to finish it would be quicker. I also was upgrading audio at the same time, routing cables, speakers etc.
Sound wise inside now, its odd as its still very much a Clio, but the doors sound different when they shut, as does the boot. The sound of the central locking has a deeper tone to it and it feels generally tighter and a bit more premium. All of the Clio'ness is still there and there's no doubting what car you're still in. Blindfolded you wouldn't all of a sudden think you're in a modern car for example. But all of the hums, rattles and buzzes that stiff Clio makes is significantly reduced.
Road noise is down massively and everything going on is more muffled and less aggressive. Yet there's still all the snap, crackle and pop from the ITG Maxogen and PMS de-catted system. Its still all there, just a bit smoother if that makes sense.
I had previously been testing the ambient noise inside the car with an iPhone app, but since my last test, i have swapped over to my summer tyres which as anyone who has used R888Rs will know, they're bloody noisy. So any results i got this morning were purely for fun to see how much improvement had been made.
I was surprised with the following results, these are the average dB readings inside the car under the following conditions.
Now i know the results are flawed, but as said before, i didn't need an iPhone app to tell me how much better it has made the car. A total drop of over 10dB and that's with noisy rubber on too, its made a noticeable difference to how nice the car is to be in day to day. However one issue is my previously vary quiet PMS shifter is now the loudest thing in the car and i will be forced to revisit shutting it up if i can.
All in its cost me about £140 for the sound deadening materials used and including the audio i have added approx. just under 20kg to the car.

I was surprised with the following results, these are the average dB readings inside the car under the following conditions.
- Decibel X app
- iPhone screen mounted phone holder
- Same section of road - A127 (A130 to Wickford)
- 5th gear
- Cruise control set to 50mph
- Totally untreated car (Michelin PS3) = 82.6dB
- Rear cabin & boot floor treated (Michelin PS3)=77.3dB
- As above plus doors treated (Michelin PS3) =74.2dB
- As above plus front cabin floor treated (Toyo R888R) =72.4dB
- Total drop in ambient road noise -10.2dB!
