Manifold and exhaust (1.4 and 1.6 Models): Description and operation

All the silencers contain a series of expansion chambers, resonators and baffles designed to give an improved exhaust system, eliminate condensation and give a longer life to the system.

A Catalytic converter is fitted to all models.

1.4 and 1.6 Models

The exhaust system consists of a front pipe, catalytic converter, an intermediate pipe which incorporates a silencer and tail pipe assembly which contains a further silencer.

2.0 Models

The exhaust system consists of a twin front pipe on Naturally aspirated models and a single front pipe on Turbo models which terminates in an expansion chamber, a catalytic converter, an intermediate pipe which incorporates a silencer and tailpipe which incorporates a further silencer.

Catalytic converter

The catalytic converter operates in a 'closed loop' system.

Closed loop system

The oxygen sensor, located in the exhaust manifold or front pipe is used to monitor the exhaust gases. The fuel E.C.U. modifies the fuelling to maintain emissions acceptable to the catalytic converter.
