Worked out great. It was the first time I used sound deadening and wanted to do it properly. After some research and talking to people, I figured if I have the time and money, do it right. After all, anything worth doing is worth overdoing. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif The company I worked for at the time shut down for 2 weeks in the summer (paid) so I just sat in my garage, drank, and tore my car apart collecting my paycheck. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif If I worked in the overseas office at the time, I would've gotten June/July/August off paid, plus 5 weeks of paid vacation per year.
I have a Subaru WRX with a decently loud exhaust, which had a noticeable drone on the highway and lots of general rattles. After completing this, there is nothing. Not a rattle, not a squeak, can't hear the exhaust with the windows up. Luckily I had the front stage installed (Rainbow's) for quite a while before doing the deadening, so I had a great before/after comparison. It was night and day with the midbass and general tightness with no road or outside noise. Also in order to get rid of the ****** license plate rattle, I used the four holes on the plate and put rubber o-rings between it and the bumper.
It's heavy though, my doors are solid and make a heavy thud when they close. The hatch can be shut by dropping it from about 3 inches, and I did notice it slightly affected acceleration. I've driven the car cross-country four times now, and the noise was exhausting and made conversations difficult before the deadening. Now my wife and I can basically whisper and it's fine, you hear the A/C more than outside noise. Best decision.
