An exhaust deflector is attachable to a muffler. The exhaust deflector includes a single-piece housing having a flange that defines an inlet aperture, an outlet wall that defines an outlet aperture, and an intermediate wall that interconnects the flange and the outlet wall. A mesh is in contact with the flange and is positioned to cover the inlet aperture. A perforated member is sandwiched between the mesh and the intermediate wall such that the perforated member and the intermediate wall cooperate to define a space. A low-density material is disposed within the space.

What is claimed is: 1. An exhaust deflector configured to be coupled to a muffler, the exhaust deflector comprising: a single-piece housing having an inlet aperture, a flange configured to be coupled to the muffler, an outlet defined by an outlet wall, and an intermediate wall between the flange and the outlet wall; a mesh adjacent the flange and positioned to cover the inlet aperture; a single piece perforated member that covers the outlet and is sandwiched between the mesh and the intermediate wall such that the perforated member and the intermediate wall cooperate to define a space; and a low-density material disposed within the space, wherein the intermediate wall includes a plurality of protrusions that increase the section area of the space with respect to sections that do not include the protrusion. 2. The exhaust deflector of claim 1, wherein the space is substantially annular. 3. The exhaust deflector of claim 1, wherein the mesh includes a plurality of openings, and wherein the size of the openings is less than about 0.024 inches. 4. The exhaust deflector of claim 1, wherein a portion of the mesh is sandwiched between the flange and the muffler. 5. The exhaust deflector of claim 1, wherein the mesh is welded to the flange. 6. The exhaust deflector of claim 1, wherein the low density material includes fiberglass. 7. The exhaust deflector of claim 1, wherein the perforated member includes a plurality of perforations and the mesh includes a plurality of mesh openings, and wherein the perforations are larger than the mesh openings. 8. An exhaust deflector configured to be coupled to a muffler, the exhaust deflector comprising: a single-piece housing having an inlet aperture, a flange configured to be coupled to the muffler, an outlet defined by an outlet wall, and an intermediate wall between the flange and the outlet wall; a mesh adjacent the flange and positioned to cover the inlet aperture; a single piece perforated member that covers the outlet and is sandwiched between the mesh and the intermediate wall such that the perforated member and the intermediate wall cooperate to define a space; and a low-density material disposed within the space, wherein the outlet wall and the intermediate wall cooperate to define an annular ridge, and wherein the perforated member engages the annular ridge. 9. The exhaust deflector of claim 1, wherein the perforated member has a curved shape. 10. The exhaust defector of claim 1, wherein the intermediate wall extends from the first wall at an oblique angle. 11. An exhaust deflector configured to be coupled to a muffler, the exhaust deflector comprising: a housing having a flange configured to be attached to the muffler, and an outer wall that extends from the flange and defines an inlet aperture; and a first mesh cooperating with the housing to at least partially define an annular space; and a second mesh that sandwiches the first mesh against the flange, wherein the housing defines an annular ridge, and wherein the first mesh engages the annular ridge. 12. The exhaust deflector of claim 11, further comprising a low-density material disposed in the space. 13. The exhaust deflector of claim 12, wherein the low-density material includes fiberglass. 14. The exhaust deflector of claim 11, wherein the first mesh includes a plurality of openings, and wherein at least one of the length and the width of the openings is less than about 0.024 inches. 15. The exhaust deflector of claim 11, wherein a portion of the first mesh is sandwiched between the flange and the muffler. 16. The exhaust deflector of claim 11, wherein the first mesh is welded to the flange. 17. An exhaust deflector configured to be coupled to a muffler, the exhaust deflector comprising: a housing having a flange configured to be attached to the muffler, and an outer wall that extends from the flange and defines an inlet aperture; and a first mesh cooperating with the housing to at least partially define an annular space; and a second mesh that sandwiches the first mesh against the flange, wherein the housing includes a plurality of protrusions that increase the section area of the space with respect to sections that do not include the protrusion. 18. The exhaust deflector of claim 11, wherein the first mesh includes a plurality of perforations and the second mesh includes a plurality of mesh openings, and wherein the perforations are larger than the mesh openings. 19. The exhaust deflector of claim 11, wherein a flow passes through the housing in a flow direction and the annular ridge extends in a direction substantially opposite the flow direction. 20. The exhaust deflector of claim 11, wherein the annular ridge is positioned immediately adjacent the outlet such that the annular ridge defines a diameter about equal to an outlet diameter. 21. The exhaust deflector of claim 8, wherein a flow passes through the housing in a flow direction and the annular ridge extends in a direction substantially opposite the flow direction. 22. The exhaust deflector of claim 8, wherein the annular ridge is positioned immediately adjacent the outlet such that the annular ridge defines a diameter about equal to an outlet diameter.
