Abstract: A vehicle includes an exhaust, a frame hanger connected to a body of the vehicle, and an isolator connecting the exhaust to a body of the vehicle via the frame hanger such that the exhaust rotates about the frame hanger. The vehicle further includes a first frame bracket having a fixing portion fixed to the body of the vehicle and an engaging portion located near the isolator at a first distance. The first distance defines a first maximum allowable displacement of the exhaust as it rotates in a first direction about the frame hanger. The vehicle may include a second frame bracket having an engaging portion located adjacent to the isolator at a second distance opposite to the first frame bracket. The second distance may define a second maximum allowable displacement of the exhaust as it rotates in a second direction about the frame hanger.

Abstract: A two-piece, stamped muffler having an integrally-attached aerodynamic shield having a flat bottom shape is disclosed. The muffler may be formed with a substantially flat lower surface. The aerodynamically-improved muffler set forth herein is provided as an aerodynamic shield that is incorporated into an extended flange provided in the shell blank, as a deflector that is attached to a muffler lower shell body and the clamshell flange such as by welding, that is separately attached to the clamshell flange only such as by welding, or that is separately attached to the lower shell only, again possibly by welding. For dual stamped mufflers, the shield may be used jointly with an incremental shield separate from, or integrated into, the spare tire well to connect the twin dual muffler shields to achieve vehicle aerodynamic requirements. A muffler having the aerodynamic shield deflects underbody air flow outside of the rear fascia cavity.
