In the process of my modifications, I used extreme dynomat on the floor, behind the seats, spare tire well and roof. I added 20.3 lbs.

Go to radio shack before you start and get one of their $30 sound level meters and get before and after results. By just adding regular automotive sound deadening carpet pad I dropped 3 dB. Do a search for "dynamat xtreme" it should bring it up.

I drive up I85 on a weekly basis. I have about 60lbs or so of sound insulation in my insight. (Brownbread, vcomp, lcomp etc). If you would like to see the results (compare noise between cars just let me know). Have fun, Rick
