I decided to get the interior of the RRS quieter by having sound dampening added throughout the floor of the vehicle and up the side panels and doors. This involved taking all the seats, carpeting and panels off. I thought they would add dynamat, but was told that this product will stiffen up after a 2 years as the silcone hardens. There used a mixture of roadkill and a new product from Treo Engineering. Had the vehicle detailed too while the seats were out, and carpets cleaned

The outcome: The RRS sounds so quiet. The resonance from the Magnaflow is very subtle. The overall road noise is very faint. There are no rattles as the matting took this away. The sound of the system is much better including the bass. The car sounds better than when it was new. There is still the wind noise and slight engine noise - I intend having them remove the interior hoodliner and have the product applied there as well as some places in the engine.

here are some pics of the work done - pretty crappy as taken by an cell phone and the detail work + pics with the Cooper LTZ's on a clean vehicle. It was cleaned last Friday and after driving around does since then - does not shine as much -but give you an idea

That's very cool. I thought of having it done myself when I first got the car years ago (the sound insulation bit), but I chickened out. I wasn't sure the shop would be able to put everything back together in one piece, and I thought the price was way too exorbitant (can't remember now, but I was quoted in the neighbor of $4K I think, inclusive of engine compartment insulation.) It looks like they did a very thorough job on yours. Is that dampening material heavy?

Thanks for sharing. :thumb:

The dampening material is very light. I am going to do the hoodliner to kill any other noise and engine hood too. It makes a world of a difference as far as interior noise and rattles not to mentioned the speaker/sub sound. Took it to a shop in Dallas that does custom audio/video and whole car restorations. They are like the west coast customs of Corona. They only charged me ~$1500 for all this.

I am having a whale of a problem with interior noise.
My car was hit and I think the shop did a poor job on the repairs.
Pople complain when i use the blue tooth phone. (lots of road noise) They keep telling me that it sounds like my windows are down.
Have you guys had this problem?

I love tan Interior... I think tan looks more luxurious than black..

anyway, tell us more about sound dampening impression.

does it eliminate lots of road noise?

sometime, when they take the whole thing a part and put it back on, it tends to rattle or not fit 100% like brand new...and that's the only my concern..

By hoodliner do you mean the roof? If so it's a very worthwhile exercise. The roof is the biggest 'flat' panel so it responds well to sound deadening. I've found it also reduces heat inside the car too. Did some basic testing a while back and found that doing the bonnet also made a significant different to the level of low frequency noise in the cabin.

I agree Bacco. Frisco you're way braver than me, unless that dude's name is Niles Banks (most british sounding name I could come up with) I wouldn't let him with in a Km of my Rangie.

Cool way to breath life into an older vehicle. I'd have trouble drawing up the courage to perform that on my own.

Did they add it to the engine bay as well (the wind noise could possibly be coming from there)?

Next up, raise the mpg's by making the Rangie more areodynamic?

Been on the road last few weeks- apologize for the delay

hoodini - do people complain when you are not using the bluetooth, could just be the bluetooth headset + lots of other folks complain about the bluetooth connectivity.

baccocafe - Yes the material really helped reduce the interior noise from the wheel well area, there is lot of empty space in the cargo area that amplifies the noise as well, including the magnaflow muffler. Running on Copper Zeons which does pick up extra noise, that this material reduced. The sound system sounds better too.Everything fits back well, and much tighter, there was a rattle in the passenger front door, took it back and was just a loose clip which they replaced. Its a shop that does lots of high end custom work and restoration. SO I knew I was in good hands. They did not have the LR scan tools to reset the airbags, so that was the only thing that needed to be taken to the dealer for - they charged these guys $50 for it.

rogan - with the hoodliner, I do mean the roof. They only went slightly up the sides, So now they will go up the pillars and the whole interior roof. Saw a before and after job of a car, and does make a diference. I am getting the bonnet\engine hood done as wel. FOr them to do the firewall etc would cost too much.

AppleChilli - the wind noise is coming from the front windshield area, along the A pillar. This insulation\sound dampening should take care of that

I've not had the hood liner done due to work and travel, so intend getting it done in the next 2 weeks or so.
