So my friend and I headed over to the junkyard to look for some parts for his Legend. While we were there, I picked up some of the lint stuff that auto manufacturers use to sound proof cars from the factory. I got two garbage bags full (about six cars worth of ripping the lint off the rear deck and behind the rear seats) for $12. I could have gotten even more but I did not fully stuff the bag full and we found a virtually unmolested black on black Legend so we stopped looking for lint.
Note: This was done on a 2002 5spd. However, virtually everything should be the same for all year IS300s. This would even work on a current gen IS should anyone be willing to try it.
I started with the rear deck, rear seats, and c-pillars. I did not expect much improvement from these areas but i am installing a sub and this should help the vibrations. To install I just cut a piece off and use some double sided tape to hold it on.
Double Layered C-Pillar:

I experienced NO FITMENT ISSUES!!!!! :crazy:
Everything went back together nicely, except the rear deck was kind of tough to get back on.
I also decided to insulate the shifter, hoping it *might* reduce transmission whine.
P.S. Anyone know what Short-Shifter that is?
I took the car for a test drive and the exhaust note seemed quieter from in the cabin. Also, the exhaust whistle (ever turn your car on without the rear seats in?) seemed quieter. The shifting was also slightly quieter, but not the whine itself. Rocking the shifter left and right produced virtually no noise, unlike before.
What I am trying to get at here is that you do not need to spend $300+ just to sound deaden a car. Auto manufacturers use this lint stuff from the factory to quiet cars. If Dynamat was so good, how come Lexus and Mercedes doesn't use it? This is an incredibly cheap alternative to expensive deadener. I have spend $12 so far and have covered my rear deck, rear seat backs, shifter, and C-Pillars, with enough left over to do my doors as well.
I plan on stuffing the doors (I expect this to make a huge difference), putting some on the lower back and under the rear seats, A-Pillars, B-Pillars, behind the center consul, possibly in the headliner, and possibly under the carpet. Im going back to the junkyard tomorrow to pick up some more. I will keep you updated.
