I have put on sound insulation mats to good effect but would like to further reduce engine noise so when drive in forest not so loud. Link to comment Share on other sites More sharing options...

I checked the numbers on the CVT cover and the muffler and they are different than the 2019 HD10 XT. I am not aware of any mufflers that would be quieter from the after market. I haven't had a chance to see if the CVT cover is insulated or thicker and have not heard what the muffler difference would be without a side by side comparison. The 2020 has 10 more horsepower so that may also play a part in the different muffler?🤔 Link to comment Share on other sites More sharing options...
