A traction battery venting system includes, among other things, an engine exhaust system that discharges engine exhaust gas to an area outside an electrified vehicle. The engine exhaust gas is emitted from an internal combustion engine of the electrified vehicle. The system further includes a sound deadening device of the engine exhaust system, a traction battery, and a battery vent system that communicates battery vent byproducts to the engine exhaust system at a position that is downstream from the sound deadening device. The battery vent byproducts are emitted from the traction battery of the electrified vehicle.
