Description

DESCRIPTION

The gas from the cylinder heads are conveyed via the manifolds (1) to the front exhaust pipe section (3) where to rubber parts limiting the transmission of vibrations.

From the front section the exhaust gases are sent to the three way catalytic converter (5) where most of the polluting substances are transformed.

The exhaust gasses go from the catalytic converter and cross three specific mufflers (8) and (9).

The connections between the various sections of the pipe are ensured by flanges and seals. The system is linked to the underbody by means of rubber mounts. Heat radiation towards the underbody - which is considerable due to the catalytic converter - is limited by a set of firewalls located between the exhaust pipe and the underbody. The system is equipped with two lambda sensors (see "Lambda sensor" description).
