Anyone done this or it's just not worth the time and money?

 

Some have done it. Here's a couple I had bookmarked:

As for time and effort, that's totally subjective.

 

Depends on what your goals are. For me, well worth it.

 

My goal is to make it quieter on the highway. Cut wind and road noise down substantially.

 

Well I will try to answer your question.

I originally did it so that I could experience my sound system better. I don't have to constantly change the volume and I can hear the music more clearly. The side benefit was that the car was much quieter.

There was a thicker glass front windshield that was introduced in the refresh to help quiet things down. When my '16's front windshield needed replacing, I thought about getting the new one but it was way, way to expensive.

If you are wanting to cut noise, then I would say do it. If cost is not a deal breaker, then use the Dynamat tiles instead of my Noico ones. You do get what you pay for. I have a link in my sig that lists the progression of my sound deadening.

I do want to do the firewall one day, and to do the wheel wells, but right now I'm pretty happy with the results. Highway driving is much better. Quieter than a '15 CRV. Not as quiet as a '08 B200, a '19 Macan or '17 128i. I can have a normal conversation at highway speeds. You will get a bit of wind noise but it's not too bad. Road noise is handled by tires.

When I got my Yakima aerodynamic roof rack, I couldn't hear it. Now after sound deadening, I can hear it slightly.

If you have any questions, just ask.
