I use earplugs when driving motorways.
I believe most of the noise comes from the wind in my Morgan.
How much increase in weight from the Dynamat? I plan to loose weight myself to improve performance of my Morgan🙈
And I will never install a radio in my Morgan, I enjoy the exhaust sound, the birds singing 🙂🐤
Not much weight added maybe 3-4 kg at most.
The reason I had the silent coat was to sound deaden a newly acquired 2015 Subaru Forester. They have a reputation for road noise and I decided that after the Merc C 350 I wanted to keep driving a quiet car. In addition, I was on a mission to eliminate a very annoying buzz and rattle from somewhere in the rear (steady).
After stripping out just about every trim trim in the car (I replaced the front speakers at the same time) and sticking every possible moving item down, I reassembled everything and still the buzz was there. Later I discovered that it was the rear centre seatbelt clip buzzing against its garage in the roof over the boot area -oh my days. It even has a factory cushion wrapped around it and is silent as long as it’s fitted into its home properly. Anyway, the Subaru is now very quiet and a joy to own so far.
By the way, I fitted JL Audio C1 speakers to the front doors that have really improved the radio/music sound quality of the stock system. The stock speakers were amazingly flimsy with a magnet that wouldn’t trouble a small screw.
