Abstract: The exhaust gas system includes a catalytic converter having an inlet and an outlet, a primary exhaust pipe, an exhaust nozzle and a secondary exhaust pipe. The primary exhaust pipe includes a proximate end and a distal end. The primary exhaust pipe may be affixed to the outlet of the catalytic converter at the proximate end of the primary exhaust pipe. The secondary exhaust pipe may be coupled to the distal end of the primary exhaust pipe via the exhaust nozzle. The exhaust nozzle includes a body region which is integral to a frustoconical defined region. The body region of the exhaust nozzle may be engaged to the distal end of the primary exhaust pipe. The frustoconical defined region of the exhaust nozzle may be engaged to the secondary exhaust pipe.
