Exhaust System: Description and Operation

The exhaust has been modified to improve flow. A double take down pipe and larger exhaust manifold are used. The system's pipe diameter is increased from 50 mm to 55 mm.
Two different take down pipes and catalytic converters are used. On manual transmission vehicles, an oval converter is used which has the oxygen sensor installed at its inlet. On vehicles with automatic transmissions the converter is round and the sensor is located in the take down pipe.
