I am thinking of buying the soundproofing kit engineered by Chipperman over the past two years. While it is expensive, I value my hearing highly. Here are a couple of links to his work. Right now he is getting flamed over his price, but the flamers can do what they want.

It looks like a lot of work tearing out the interior and such, and I am posting because there may be someone out there who is also interested in reducing noise and would like to see how the kit goes in. Is there anyone who is interested in helping me goop up my S?

 

tenblade might be interested. You should PM him. I saw his posts in the original thread about the development of this kit.

Its all pretty easy and just snaps in place. I had to tear apart the whole passenger side to get all my stereo stuff in and you should have no problem.
