My 2021 Trail Boss LT has developed a rattle from the undercarriage. I have noticed it around 1500 RPM while coasting. The truck is equipped with a cat back exhaust (adaptive valve is gone.) I have been under the vehicle and did not find any issues with heat shields, drive shaft, or any other components. Anybody else experience this?
 
As wierd as it maybe..my O2 sensors came loose and were rattling around in the exhaust. Never touched them before so not sure how they just came loose overtime.
 
I removed all the empty beer cans and the problem resolved itself! :ROFLMAO::ROFLMAO::ROFLMAO::ROFLMAO:
