This gasoline engine exhaust system is equipped with 2
three way catalytic converters, located between the exhaust manifolds and
the exhaust mufflers. Each catalytic converter is a separate unit, mounted
in combination with the takedown and intermediate exhaust pipes. The catalytic
converters are emission control devices that reduce emissions of the following
gases:
The catalytic converter contains a honeycomb network coated with a catalytic
material containing platinum and rhodium. The catalytic material promotes
the burning or oxidation of the oxidants as the exhaust gases pass through
the catalytic converter towards the tailpipe.
The catalytic converter requires the use of unleaded gas in order to
perform the following functions:
| • | Reduce combustion chamber deposits |
| • | Reduce spark plug fouling |
| • | Prevent lead contamination of the catalytic converter, resulting
in premature failure and the loss of emission system warranty coverage |
