I've used Decibel X on my top at 75 and found it registered around 85-88 with the top, and not a significant change with the new headliner installed.I just purchased the liner and really hoping it works. These tops are great but a nightmare when you want to accessories, (i.e. a rooftop tent). I installed the Garvin Industries exoskeleton Adventure rack and the sound was deafening due to the round bar right over the drivers head then added a Roofnest, even worse.
For comparison, I used the Decibel X app. Stopped and at idle 55 db, with rack and tent at 75mph, average 85db. Has anyone, by chance, measured the db's with the liner?
At this point I'm not happy with this aspect of my build. I don't keep the rack and tent on all the time and use the garagesmart lift system to remove them when not in use. Has anyone used gutter rail brackets for their rack/tent?
Any help would be greatly appreciated.
I've seriously considered swapping someone for their hardtop with my powertop.
