I don't really care all that much about 'quality of ride' (in a 13-year-old car, it's laughable) so I went ahead and scrapped the sound deadening.

Results: At final tally, 18+ pounds of crap.

What I removed: all the sound deadening from the driver's and passenger's side seat bays, all the deadening from the rear hatch area, (I used a chisel and hammer to chip it off... works best if you start from the INSIDE and chip OUT instead of trying to pry underneath it), the foamy stuff from the front firewall (that stuff was HEAVY - I just ripped out what I could reach), and the layer of rubbery stuff underneath the storage box.

How long it took: Too long. Probably a good 2 days of chipping away hardened, disgusting, gooey tar. Oh well, 18 lbs is pretty substantial.

 

YEAH IT IS

you prolly gained about nothing in speed and weight savings for it hehe j/k but congrats on the effort. sound deadening sucks.

 

A friend of mine did this and he used crushed dry ice to "freeze" the sound deadening material. It then came up very easy w/ a chisel in big chunks. Probably the way I'm going to do it, 18 pounds is good a bit out of 2000 lb car, almost 1%.
