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.
