Patent ID: 7510051

Claim:
A switchable exhaust system apparatus, comprising in combination: a primary pipe with a first end to receive exhaust gases from exhaust system and a second end to discharge the exhaust gases with a plurality of holes around the first end, wherein exhaust gases from the exhaust system are forced out though the plurality of holes around the first end or directly out of the second end depending on a position of a butterfly valve in an actuator assembly within the primary pipe; a secondary pipe with a first end to received exhaust gases and a second end to discharge exhaust gases, wherein a plurality of portions are removed from the secondary pipe and covered with a plurality of screens, wherein the primary pipe is placed inside the secondary pipe and wherein exhaust gases from the plurality of holes from the primary pipe are forced out of the primary pipe and out of the of the plurality of sections covered with the plurality of screens in the secondary pipe or at the second end of the secondary pipe depending on the position of the butterfly valve; a third pipe with a first end to received exhaust gases and a second end to discharge exhaust gases placed over the secondary pipe, wherein portions of the actuator assembly are connected outside and through the first end of the third pipe, second pipe and first pipe and a nose cone placed over the second end of the third pipe to connect to the exhaust system; and the actuator assembly including two more pneumatic dual action cylinders, a pneumatic toggle switch to supply pressure to the two or more pneumatic dual action cylinders to open or close the butterfly valve, an electrical compressor to supply pressure to the pneumatic toggle switch, and a pressure switch for maintaining a constant air pressure to the electrical compressor, wherein the exhaust system apparatus is switchable via the actuator assembly between a loud mode and a quiet mode via the pneumatic toggle switch.
