Abstract
A vehicle exhaust component includes an outer shell defining an internal cavity, at least one baffle located within the internal cavity, and at least one tube supported by the baffle. The baffle is fixed to the outer shell and includes at least one opening. The tube has first and second tube ends with one of the first and second tube ends being supported within the opening in the baffle. At least one slot is formed within the one of the first and second tube ends at the at least one opening. The slot facilitates noise reduction during cool down of the vehicle exhaust component.
