Aftermarket muffler

[DaveJ]

Has anybody put on aftermarket muffler or modification to reduce engine noise in defender max.  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.

The 2020 are advertised as being much quieter in the cab; due to better noise insulation, CVT cover insulation and different exhaust system. 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?
