Re: air vents in back of cab
These vents have rubber flaps in them that open to allow cab pressure to escape. This aids in the cab ventilation. If you seal these, you will decrease the performance of the HVAC system. They should not allow an increase in muffler sound entering the cab. Do you have short exhaust dumps ahead of the rear axle?
