An HVAC duct system of a vehicle includes an air duct for providing a passageway for forced conditioned air. The air duct having a first imaginary axis extending substantially parallel with the passageway. An air duct register having plurality of vane-like members for directing the flow of air as it exits the register is coupled to the air duct. An opening of the air duct register defines an imaginary plane. The register has a second imaginary axis extending perpendicular to the imaginary plane of the register. An air flow straightener disposed within the air duct juxtaposed to the register and includes an air guide member. The air guide member receives the forced air flowing through the air duct in a direction substantially parallel with the first imaginary axis and redirects the forced air in a direction substantially parallel with the second imaginary axis for reducing noise as air passes the vanes.
