An apparatus, system, and method for cooling exhaust gases includes an inlet operatively connected to an exhaust port from a diesel engine or the like, and a housing defining a substantially enclosed volume. At least a portion of the volume is larger in cross-section than the inlet in cross-section, such that the exhaust gases expand upon entering the housing from the inlet. At least one outlet larger in collective cross-section than the inlet in cross-section is disposed on the housing and configured to expel the exhaust gases from the housing into the atmosphere.

What is claimed is: 1. A method of cooling exhaust gases, the method comprising: urging the gases through a first passage; urging the gases from an outlet of the first passage into a substantially enclosed volume, the substantially enclosed volume being elongate in a first direction extending from the first passage to a distal end of the volume, wherein the gases flow through an inlet of the volume in the first direction; allowing the gases to expand within the volume, a portion of the volume having a cross-sectional area greater than a cross-sectional area of the outlet of the first passage; redirecting the flow of gases through the volume from the first direction to a second direction substantially angled relative to the first direction using a plurality of baffles positioned within the elongate substantially enclosed volume, the baffles being substantially angled with respect to the first direction; and urging the gases from the enclosed volume to the atmosphere through a plurality of outlets, wherein the gases flow through the plurality of outlets in the second direction. 2. The method of claim 1, wherein the plurality of outlets are greater in collective cross-sectional area than the cross-sectional area of the outlet of the first passage. 3. The method of claim 1, further comprising slowing the collective velocity of the exhaust gases within the enclosed volume. 4. The method of claim 1, further comprising generating the exhaust gases from an internal combustion engine operatively attached to the first passage. 5. The method of claim 1, further comprising treating the exhaust gases before urging the exhaust gases into the enclosed volume. 6. An apparatus for cooling exhaust gases, the apparatus comprising: an inlet pipe operatively connected to a source of exhaust gases, the exhaust gases being flowable through the inlet pipe in a first direction; a housing defining a substantially enclosed volume into which a portion of the inlet pipe extends, at least a portion of the volume being larger in cross-section than the inlet pipe in cross-section, the housing configured to receive the exhaust gases through an opening formed in the portion of the inlet pipe extending into the volume, a substantial portion of the exhaust gases exiting the opening in a second direction substantially perpendicular to the first direction; and a plurality of outlets disposed on the housing and configured to expel the exhaust gases from the housing into the atmosphere, wherein a substantial portion of the exhaust gases are expelled through the plurality of outlets in a third direction substantially opposite the second direction. 7. The apparatus of claim 6, wherein the inlet pipe is configured to connect to an exhaust treatment device. 8. The apparatus of claim 6, wherein the size of the plurality of outlets is larger in cross-section than the size of the inlet pipe in cross-section. 9. The apparatus of claim 8, wherein the outlets comprise a series of apertures disposed on a side of the housing. 10. The apparatus of claim 6, wherein the plurality of outlets comprises a series of elongate slots disposed along the side of the housing, the elongate slots extending lengthwise in a direction substantially parallel to the first direction. 11. The apparatus of claim 10, wherein the cross-sectional area of the elongate volume is greater near the inlet than near the distal end. 12. The apparatus of claim 1, further comprising a baffle disposed within the housing to direct flow of the exhaust gases. 13. The apparatus of claim 12, wherein the baffle is configured to decrease the cross-sectional area of the elongate volume as the exhaust gas travels from the inlet toward a distal end opposite the inlet. 14. An exhaust pipe apparatus operatively connecting an exhaust port of an internal combustion engine to the atmosphere, the apparatus configured to carry exhaust gases from the engine to the atmosphere, the apparatus comprising: a first passage configured to receive exhaust gases; a housing operatively connected to the first passage for reception of exhaust gases from the passage, the housing defining a substantially enclosed volume configured such that the exhaust gases expand upon entering the housing from the first passage; and a plurality of second passages configured to expel the exhaust gases from the housing into the atmosphere, the second passages being larger in collective cross-section than the first passage; wherein the first passage is configured to be positioned vertically and the housing is relatively flat and configured to be positioned horizontally, a front portion of the housing connecting to the first passage at approximately right angles to the first passage, the front portion of the housing being approximately the same in cross-sectional area as the first passage in cross-sectional area, the housing becoming wider and larger in cross-sectional area toward a rear portion of the housing, and wherein the second passages are disposed on the rear portion of the housing. 15. The apparatus of claim 14, wherein at least part of the housing volume is larger in cross-section than the first passage in cross-section. 16. The apparatus of claim 14, wherein the at least part of the housing volume is larger in cross-section than the second passages in collective cross-section. 17. The apparatus of claim 14, wherein the second passages comprise apertures in the housing. 18. The apparatus of claim 14, further comprising an exhaust treatment device disposed substantially within the housing. 19. The apparatus of claim 18, further comprising a baffle configured to change the direction of the exhaust gas stream. 20. A diesel engine exhaust treatment and cooling system, the system comprising: an exhaust pipe substantially containing and directing exhaust gases generated by the engine; and a cooling mechanism disposed on the exhaust pipe and configured to receive exhaust gases from the exhaust pipe, the cooling mechanism comprising a substantially enclosed volume, a part of which is greater in cross-section than the exhaust pipe in cross-section, the cooling mechanism further comprising at least one outlet through which the exhaust gases enter the atmosphere from the substantially enclosed volume; wherein the substantially enclosed volume comprises an elongate volume extending from an inlet to a distal end opposite the inlet, the cross-sectional area of the elongate volume being greater near the inlet than near the distal end. 21. The system of claim 20, further comprising an exhaust treatment mechanism disposed on the exhaust pipe, the exhaust treatment mechanism configured to modify the composition of the exhaust gases, and further comprising a regeneration mechanism operatively attached to the exhaust treatment mechanism, the regeneration mechanism configured to regenerate the exhaust treatment mechanism from time to time. 22. The system of claim 20, wherein the at least one outlet comprises a plurality of elongate slots each extending lengthwise in a direction substantially perpendicular to a length of the elongate volume. 23. The system of claim 20, wherein the at least one outlet comprises a plurality of outlets. 24. The system of claim 23, wherein the outlets comprise slots. 25. The system of claim 20, wherein the substantially enclosed volume is defined by an elongate housing, and further comprising a baffle disposed within the elongate housing, the baffle configured to modify the flow of the exhaust gases within the housing. 26. The system of claim 25, wherein the baffle is configured to decrease the cross-sectional area of the elongate volume as the exhaust gas travels from the inlet toward the distal end.
