Abstract
Exhaust routing devices are disclosed that include (a) a body defining an exhaust routing chamber, the body having an intake port configured to provide fluid communication between the exhaust port of a cylinder head and the chamber, and two outlet ports configured to provide fluid communication between the chamber and first and second exhaust pipes; and (b) a gate, mounted within the chamber to pivot between a first position, in which the gate occludes one of the outlet ports, and a second position, in which the gate occludes the other outlet port. Exhaust routing systems and method of using them are also disclosed.
Claims17
An exhaust routing device comprising:
- a body defining an exhaust routing chamber, the body having an intake port configured to be mounted at an exhaust port of an engine and provide fluid communication between the exhaust port and the chamber, a first outlet port configured to provide fluid communication between the chamber and a zoomie and a second outlet port configured to provide fluid communication between the chamber and a header pipe to a muffler system, the body including a chamfered seat portion;
- and
- a gate, mounted within the chamber to pivot between a first position, in which the gate occludes the first outlet port, and a second position, in which the gate occludes the second outlet port, the gate having an arcuate surface and including a chamfered portion which seals against the chamfered portion of the body when the gate is in the first position.

13-18. (canceled)
A method of routing exhaust from an internal combustion engine, the method comprising:
- rotating the gates of a plurality of exhaust routing devices between a first position, in which the exhaust takes a first route, through a header pipe to a muffler, and a second position, in which the exhaust takes a second route, through a zoomie,
- each exhaust routing device being mounted at the exhaust port of an engine, and each exhaust routing device comprising:
- (a) a body defining an exhaust routing chamber, the body having an intake port configured to be mounted at an exhaust port of an engine and provide fluid communication between the exhaust port and the chamber, a first outlet port configured to provide fluid communication between the chamber and a zoomie and a second outlet port configured to provide fluid communication between the chamber and a header pipe to a muffler system, the body including a chamfered seat portion;
- and
- (b) the gate, which is mounted within the chamber to pivot between a first position, in which the gate occludes the first outlet port, and a second position, in which the gate occludes the second outlet port, the gate having an arcuate surface and including a chamfered portion which seals against the chamfered portion of the body when the gate is in the first position.
