There’s no good reason to install a barrier on the roof. Barriers block noise coming at them in a straight line. There aren’t enough noise sources directly overhead to warrant the difficult installation and added weight at the highest point in the vehicle. Beyond that, the windows become the weak link after you install a barrier below the glass line.
I decided to follow his suggestion and not add MLV to the headliner.

Ok. Your previous comment suggested that you may have been expecting that, I misunderstood that. My MLV comment was a general statement. Many folks confuse deadener for blocker. Sounds like it doesn't make such sense to put a blocker in the roof. Good thing I never did

Default How much quieter

That is a lot of work, but I can imagine it made the drone sound from the exhaust disappear? Finished product looks great, good work.

Thanks! Took a nice drive today with my wife and she said "your car is quieter now"... mission accomplished.
