Sound Deadening

Just wanted to share... I didn't see a ton of post already about this, so starting a new Post. We ran into a group of guys with 3 KRX's a few weeks ago at Interlake and as we where BS'in with them, one of them showed us this KilMat sound/heat deadening that he put on the back of his rear...

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

I was serious as this is the simplest, cheapest most effective thing that I have found.

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

Headsets with an intercom was our solution....

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 enjoy the noise, it means I can’t hear anyone

After the fifth time they speak:

“WHAT? Did you say something?”

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.

Where are you coating it from?

Plastic bed cover behind where a rear windshield goes. Think it's only 3 pins to take out.
