I'm too cheap to fork over $4k for Tesla's noise reduction kit so I did an alternate route.
Someone recommended using RaamAudio instead of Dynamat cuz its supposed to be better and slightly cheaper. So I bought RaamAudio padding.
Had my trusty local guy install it along with the HID kit. Covered floor, back, inside doors.
Here's what I'm noticing:
a)very significant improvement when going over bumps and stuff. Much more muffled and car feels more solid.
b)very little improvement on road noise. Sort of expected as nothing was done on wheel wells. And with shockingly high Washington State road noises, I wasn't really expecting miracles.
c)my feet are warmer.
Overall, I'm happy.
