Sound deadening in s-chassis

[JZenki]

Need some opinions&tips from who has done this, some pics would help..

Coming from a previous m3 owner, I truly miss the quiet cabin and minimal engine vibration shaking the chassis.. I plan on installing it through out the full chassis, roof, pillars, trunk and just about anywhere you can think of, so I can achieve that good luxury modern feel as this will serve as my daily driver for the years to come..
