The present invention provides an exhaust system for use on a motorcycle having an internal combustion engine with at least one exhaust port, the exhaust system including a first tubular member having a first end removeably coupled to the exhaust port of the internal combustion engine, and a second end, opposite the first end, forming a first connector. Where the first tubular member also includes a catalytic element positioned within the first tubular member between the first end and the second end, and where the first tubular member is gas-tight such that all exhaust gas entering the first end must pass through the catalytic element before exiting the second end. The exhaust system also includes a second member removeably coupled to the first connector of the first member, the second member having one or more baffles positioned therein.

The present invention provides an air intake assembly including a first portion defining a first chamber through which airflow passes. The first portion is coupled to a first throttle member to allow communication from the first chamber to the first throttle member. The air intake assembly also includes a first filter element coupled to the first portion and positioned upstream of the first chamber, and a second portion defining a second chamber through which airflow passes. The second portion is coupled to a second throttle member to allow communication from the second chamber to the second throttle member. The air intake assembly further includes a second filter element coupled to the second portion and positioned upstream of the second chamber, and a conduit coupling the first and second portions. The conduit allows communication between the first and second chambers at a location downstream of the first and second filter elements.
