Has anyone had the door panels or rear tailgate panel off an 07 RX?

I'm curious to know how much insulation is in the doors from the factory and if adding dynamat extreme to the doors and rear tailgate would make a worthwhile difference. Lexus supposedly increased sound deadening in the 07 model year on this vehicle, but I haven't found any specifics as to where it was added.

To me, the RX is noticeably less quiet inside than my GX470. One thing I notice from the outside, is that when the stereo is turned on, even at a low volume level such as 8, the amount of stereo noise/music that you can hear from outside the vehicle is significantly higher than in the GX. The vehicle definitely isn't as quiet as the GX from the inside either...

Thanks,
Jim
