QH13R mods,questions &answers

Hi all new to the community here. Just bought a 2025 QH13R cab for use in the PNW. Picking it up this week and getting my list of mods and parts ready.

One initial question I have is, has anyone tried incorporating sound dampening around the cab/under the seat? Thoughts?

Additionally, trying to identify methods to cool/keep the engine cool in addition to fans. Has anyone added a bolt on exhaust extension and used heat wrap around exhaust housing? My concern is blocking air flow if I wrap the housing.

Also considering new wider tracks to help with the stability such as 2307232 has anyone upgraded to this width before on an QH13R?

Looking forward to receiving input and providing pics 📸 and further updates cheers!
