Hello, I purchased a 2021 Defender XT HD10 back in September and I love it. I have added front flip out windshield, back window, roof, hard doors, and a few other accessories (I know, I should've just bought a Limited, but it's a long story). I took a ride in my buddy's new Limited the other day and it is much, much quieter than mine. Essentially we have the exact same cab, so why is his so much quieter? I have searched for a Can-Am insulation kit or something to help with the noise, but really haven't found anything. If you look on their site, it says the Limited comes with the "insulation kit", but they don't provide a part number so you can buy it separately. I've ran across a couple potential products (Can-Am Cab Insulation Kit for Defender | 715004911 & Can-AM OEM Liner Kit | 705800581) but neither provides really any helpful info/description of what they include. Any suggestions for an OEM solution?? I would appreciate it!!
