I bought a trigger shield earlier this year. It was definitely a great addition to the P520.
The 520 is a little easier to get to the area above the muffler, I plan on creating a heat shield that’s insulated with some sound deadening material that goes over the area where the stock muffler is at. This should further cut down on noise.
I also plan on creating a rubber flap that is at the front edge of the dump bed near the passenger compartment. It should help seal off some of the noise coming from the back end of the vehicle to.
I’m also looking for some stick on rubber mat that I can place on the underside of the roof. There was a distinct noise level increase when we put the windshield and the top on. I feel like the sound just bounces around those hard surfaces with nothing to absorb it.
