I'm back with an update! Thank you to my fellow enthusiast's recommendation! The only way to go is removing the old headliner & replacing it with a new one! Added some insulation AND Dash Cam wiring. If you're in the SF bay area, i used Pacific Coast Custom Interiors, in Santa Rosa - not cheap, nor crazy expensive, but top quality materials and workmanship! Here are some pics of during and completed!


During - old headliner is gone, new insulation and dash cam are in!

Completed Job - looks great! Quieter too!
