AENAW1011B01001Page 1 of 11KExhaust System DescriptionThe exhaust system consists of a exhaust manifold with a Warm Up Three-Way Catalytic

converter (WU-TWC), exhaust No.1 pipe with a Three-Way Catalytic converter (TWC),

exhaust No.2 pipe, a muffler, a gasket, etc. The WU-TWC and TWC are emission control

devices which are added to the exhaust to lower the levels of Hydrocarbon (HC), Carbon

Monoxide (CO), and Oxides of Nitrogen (NOx) pollutants in the exhaust gas. A large capacity

sub-muffler is combined with the exhaust pipe No.2 for reducing booming noises at low-mid

engine speeds. The adoption of a dual muffler produces low exhaust resistance and low back

pressure, improves engine power and keeps exhaust noise :///Media/Manuals/Kizashi/2010/Service_7/20/2010

In order to help avoid getting burned, do not work on exhaust system when it

is hot. Exhaust system must be sufficiently cool before beginning any service

on the exhaust system at every periodic vehicle inspection and when the vehicle is

hoisted for other service noting the following points:•Check rubber mountings for damage deterioration and incorrect position.

•••••Check mating surface of cylinder head with exhaust manifold for distortion.

Check exhaust system for exhaust gas leakage, loose connection, dent and damage.

Check if bolts or nuts are loosened, and then tighten them to specified torque.

Check any damages, holes or cracks which may permit exhaust gas to enter the vehicle.

Check to make sure that exhaust system components have enough clearance from other

underbody components to avoid overheating and possible damage to these components.

•Check for any defects and fix them whenever found.
