A muffler exhaust tip has a first end provided with clamping members and a second end having a decorative exterior finish. The construction of the muffler tip allows the manufacturer to provide multiple decorative exterior finishes on the muffler tip body. Two adjustable clamping members facilitate attachment of the muffler tip to an exhaust pipe of a motor vehicle. The clamping members attach to the tailpipe of a muffler with a high retention force and can accommodate tailpipes of different diameters for a "universal" fit. A sound amplifying member is set inside the muffler tip, comprising a dual plate member which increases the sound decibel output from the tailpipe and also provides an attractive end cover for the muffler tip.

In one exemplary embodiment, an exhaust dilution and dispersion device for a vehicle can include a generally elongate tailpipe comprising an inlet section capable of being in exhaust receiving communication with an exhaust system of a vehicle. The tailpipe further comprises an outlet section in exhaust receiving communication with the inlet section. The outlet section can also comprise a downwardly directed exhaust deflection portion and an exhaust outlet in exhaust dispersing communication with the surroundings external to the device. The exhaust outlet can comprise a generally elongate exhaust dispersion opening extending in a lengthwise direction along the tailpipe. At least a portion of the exhaust outlet can be coextensive with the downwardly directed exhaust deflecting portion and a major portion of the exhaust dispersed from the outlet can have a transverse component.

Vehicle exhaust dilution and dispersion device

An exhaust diffuser is disclosed for coupling to an exhaust system of a vehicle that, when in one orientation, is designed to exhaust gasses laterally and downwardly from the exhaust diffuser.

A muffler exhaust tip for a vehicle having a muffler tailpipe includes a substantially hollow, cylindrical muffler tip member with an inboard end adapted to be affixed to the tailpipe and an outboard end. The hollow, cylindrical member is defined by an elongated outer sleeve and a coaxial, perforated inner sleeve which jointly define a baffle interspace therebetween. The inner sleeve carries a plurality of radially inboard protrusions to alter exhaust flow through the muffler exhaust tip. The perforated inner sleeve of the cylindrical member may define a pattern of holes. The baffle interspace may include a layer of fire retardant sound baffling material. The plurality of inboard protrusions define a helix extending through part of the inner sleeve in one embodiment. In another embodiment, part of the outer sleeve of the muffler tip includes a conical reducer such that the inboard end matches the dimensions of the tailpipe.

A clamping member ( 2 ) for clamping a periphery of a rear-end open portion of an exhaust pipe ( 3 ) is accommodated in a front-end open portion ( 11 ) of a tail pipe ( 1 ) The clamping member ( 2 ) has a pair of plate parts ( 21, 22 ) disposed at right and left positions of the front-end open portion ( 11 ) and a bolt ( 4 ) for connecting the plate parts ( 21, 22 ) to each other by reducing an interval between the opposed plate parts enough to sandwich a periphery of the rear-end open portion ( 31 ) between the plate parts A concave surface ( 21 a , 22 a ) whose configuration conforms to that of a periphery of the rear-end open portion ( 31 ) inserted between the plate parts ( 21, 22 ) is formed on each of the plate parts ( 21, 22 )
