Abstract: An exhaust assembly for a vehicle includes a hanger and an exhaust pipe assembly. The hanger is configured to be fixed to a body of the vehicle. The exhaust pipe assembly includes a first portion and a second portion. The first portion is at least partially disposed inside the second portion so that the second portion overlaps the first portion at a joining region. The joining region has a first outer diameter and is flanked by outer regions having a second outer diameter that is greater than the first outer diameter. An interference fit may be provided between the first portion and the second portion. The hanger is joined to an outer surface of the exhaust pipe assembly at the joining region.
