1. A method of controlling a discharge of an exhaust gas from a pneumatic device, comprising: directing the exhaust gas from an exhaust port of the pneumatic device into proximity with a heated portion of the pneumatic device;expanding in an expansion chamber the exhaust gas in proximity with the heated portion of the pneumatic device to heat the exhaust gas; anddischarging the exhaust gas to atmosphere. 2. The method of claim 1, wherein directing the exhaust gas from the exhaust port of the pneumatic device into proximity with the heated portion of the pneumatic device includes maintaining the exhaust gas at substantially the same pressure as when the exhaust gas is vented from the exhaust port. 3. The method of claim 1, wherein expanding the exhaust gas in proximity with the heated portion of the pneumatic device includes expanding the exhaust gas in a front portion of a cylinder of the pneumatic device. 4. The method of claim 1, further comprising a passing of the exhaust gas through a silencer device after expanding the exhaust gas in proximity with the heated portion of the pneumatic device and before discharging the exhaust gas to atmosphere. 5. A muffler system for controlling expansion of exhaust gas from a pneumatic device, comprising: a housing having a first housing portion including: a first portion configured to receive an exhaust gas from a pneumatic device; anda second portion comprising an expansion chamber, the expansion chamber being fluidly coupled to the first portion, the second portion being configured to be placed in proximity to a heated portion of a pneumatic device. 6. The device of claim 5, further comprising a third portion fluidly coupled to the second portion and configured to change a direction of a flow of an exhaust gas the third portion receives from the second portion. 7. The device of claim 6, further comprising a silencer device fluidly coupled to the third portion. 8. The device of claim 7, wherein the third portion extends radially away from the second portion. 9. The device of claim 5, wherein the first portion is configured to direct exhaust gas from the pneumatic device to the second portion while maintaining a pressure of an exhaust gas. 10. The device of claim 5, wherein the first portion is configured to sealingly engage a cylinder of a rock drill and wherein the first portion is configured to extend toward a front portion of a cylinder of a rock drill. 11. The device of claim 5, wherein the second portion is configured to sealingly engage a front portion of a cylinder of a rock drill. 12. The device of claim 5, further comprising a second housing portion including a first portion configured to receive exhaust gas from a pneumatic device; and a second portion fluidly coupled to the first portion, the second portion being configured to be placed in proximity to the heated portion of a pneumatic device, the second portion being shaped to allow exhaust gas to expand therein. 13. The device of claim 12, wherein the first housing portion and the second housing portion are configured to be fastened to a pneumatic device. 14. A pneumatic system, comprising: a pneumatic device including an exhaust port and a heated portion; anda muffler system fluidly coupled to the exhaust port, the muffler system including a housing having a first housing portion including a first portion configured to receive exhaust gas from a pneumatic device, and a second portion comprising an expansion chamber, the expansion chamber being fluidly coupled to the first portion, the second portion being configured to be placed in proximity to the heated portion of a pneumatic device. 15. The system of claim 14, wherein the pneumatic device includes a cylinder having a outer wall, a rear portion, and a front portion. 16. The system of claim 15, wherein the front portion of the cylinder is the heated portion of the pneumatic device. 17. The system of claim 16, wherein the front portion of the cylinder is heated by at least one of reciprocation of a piston within the cylinder or compression of a gas within the cylinder. 18. The system of claim 17, wherein the pneumatic device is a rock drill. 19. The system of claim 15, wherein the first portion is sealingly coupled to the outer wall. 20. The system of claim 15, wherein the second portion is sealingly coupled to the outer wall near a front portion of the cylinder. 21. The system of claim 15, further comprising a second housing portion, wherein the first housing portion includes first flanges and the second housing portion includes second flanges, wherein the first flanges are configured to be fastened to the second flanges to secure the muffler system to the pneumatic device.
