EXHAUST PIPE AND MUFFLER

<4A9, 4B10, BWC>

• Due to the adoption of rear exhaust layout, the exhaust pipe length has been shortened, the exhaust gas temperature drop at engine start has been prevented, and the early-activation of catalytic converter has been accelerated, which reduces the exhaust gas.
  
• The front exhaust pipe <4A9-A/T> and centre exhaust pipe are integrated with the catalytic converter to reduce the exhaust emission.
  
• Due to the rear exhaust layout, the exhaust pipe length has been shortened, and the exhaust pressure has been reduced, which improves the engine performance.
  
• The diameter of centre exhaust pipe has been increased, and the exhaust pressure has been reduced, which improves the engine performance.
  
• Enlarged pre-muffler reduces exhaust noise.
  
• The large exhaust main muffler has been adopted to reduce the exhaust noise.
  
• A 4-point exhaust muffler hanger has been adopted for optimisation of position, which reduces vibration to the vehicle.
  
• The spherical joint has been adopted for connection between the front exhaust pipe and the exhaust manifold, and between the exhaust main fitting and the centre exhaust pipe, which reduces vibration to the vehicle. <4A9, 4B10>
  
• The large-diameter elliptic exhaust tail pipe diffuser has been adopted to create the sporty feeling. <4B10 (some models)>

• Enlarged pre-muffler reduces exhaust noise.
  
• The capacity of exhaust main muffler has been increased, and two tail pipes have been adopted, which improves the engine performance.

• The spherical joint has been adopted for connection between the front exhaust pipe and the exhaust manifold, and between the exhaust main fitting and the centre exhaust pipe, which reduces vibration to the vehicle.
  
• The two tail pipes for the exhaust main muffler and the large-diameter elliptic exhaust tail pipe diffuser have been adopted, which enhances the sporty image.
