I know you wanted a serious answer and I apologize in advance for answering that I wear hearing protection. WorkTunes bluetooth headphones from 3M. This is an extremely loud machine and these headphones fix that for me.

Wear Ear Protection
Or go slower 😃

Thanks we went to pack talk head phones. Was hoping for a miracle exhaust system. I'll have to turn the volume up.

What I’ve also seen in engine covers in the auto industry is the valve cover will have a thick sound deadening material to quiet the noise of the valve train injectors etc. Not sure where most of the noise is made but that would be a start

I used a hood insulation blanket on the rear firewall. Another huge difference was dynamating the removable cover in the bed up by the rear window. Think that alone was 6 or 7 decibels. My buddy did a before and after with a tester. Removing the primary spring is a big difference also.

I did the rear cover in Noico or whatever it is called and definitely made the biggest difference. I also used a large vacuum hose to find the source and it was mostly all from the clutch exhaust tube. Gonna add a second coat since I have a lot left.
