Just thought I would add my experience. I used some closed cell insulation with radiant barrier on both sides to line the engine cover. I removed the stock intake snorkel. I used the same insulation to fill between the bed and the cab. I a bought a cheap muffler and added it in series with the stocker with pieces and parts from autozone. All of these mods put together made my rhino significantly quieter. I can now talk to the person in the passenger seat while riding. No change in performance. Didn't cost much and only took a couple of hours. Best mods so far.
Clemebone, do you still have the same Rhino and if so how is the 1" sound and heat foam under console holding up? This past Friday I installed the Ryde-on dust cover on our 2005 Rhino. It most definitely reduced the dust but causing the motor to overheat. U removed the dust cover and did not experience any overheating issue. This is really disappointing as I was really looking forward to riding almost dust free. The bulk of the heat seamed to be directly under the console when the dust guard was installed.Just wanted to give my update. I installed the 1" sound and heat foam under console and ryde on dust guard. Huge improvement. Almost like riding in truck with windows down. The dust cover and rear window blocks out exhaust noise also. As far as dust I'll have to get back. Been under tropical storm here in Panama City so not much dust around.
