EXHAUST PIPE AND MAIN MUFFLER
M2150012000026
A 4-piece type of exhaust pipe and muffler which
consists of the front exhaust pipe, catalytic converter,
center exhaust pipe and exhaust main muffler has
been adopted, and has the following features:
• 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 cata-
lytic converter has been accelerated, which
reduces the exhaust gas.
• The diameter of front exhaust pipe has been
increased, and the exhaust pressure has been
reduced, which improves the engine perfor-
mance.
• The capacity of exhaust main muffler has been
increased, and two tail pipes have been adopted,
which improves the engine performance.
• A 4-point exhaust muffler hanger has been
adopted for optimization of position, which
reduces vibration to the vehicle.
• The spherical joint has been adopted for connec-
tion between the front exhaust pipe and the
exhaust manifold, and between the exhaust main
fitting and the center 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.
