1. A system for cooling a device secured to a portion of a combustion exhaust pipe included in a vehicle, the system comprising:
a drivetrain duct that includes a first aperture and a second aperture, wherein
the first aperture is coupled to a drivetrain aperture included in a drivetrain of the vehicle and the second aperture is positioned immediately proximate the portion of the combustion exhaust pipe to which the device is secured such that the second aperture is directed at a volume immediately proximate the device, and
wherein when the drivetrain is engaged, the portion of the combustion exhaust pipe is at a first temperature and the drivetrain outputs drivetrain exhaust gas through the drivetrain aperture such that the drivetrain exhaust gas is at a second temperature lower than the first temperature and the second aperture provides at least a portion of the drivetrain exhaust gas to the volume immediately proximate the combustion exhaust pipe to which the device is secured.
