This document is a collection of my notes and various links to other articles that outline how to sound dampen a 2008 VW GTI. I am not responsible if you damage your vehicle following these instructions and don’t claim to be a VW tech nor do I claim that this is the “best” way to sound dampen a vehicle. However, I do think that this is a good start for anyone who wants to do this modification and I am happy with the overall outcome (see: Part 7: Results).
