EXHAUST SYSTEM OUTLINE
Features
• The exhaust system (including the exhaust manifold) has been laid out as straight as possible in order to
achieve smooth flow of exhaust gas and maintain high power output. Additionally, a large-bore exhaust pipe
and a high-capacity main silencer with an inlet pipe that passes through the center of the main silencer body
have been adopted to reduce exhaust resistance.
• Double wall piping has been adopted for the exhaust manifold to prevent lowering of exhaust gas temperature
and facilitates rapid catalyzer activation after cold engine starting for improved exhaust purification.
