Brief description, V6


The exhaust system is designed to lead out the engine exhausts with low flow-through resistance, low noise level and long service life.

Exhaust gases are collected by two exhaust manifolds, one for each cylinder bank. Exhaust gases are led via the turbocharger into the front pipe. They are then cleaned in the primary catalytic converter and the main catalytic converter before reaching the exit pipe and the atmosphere.

The exhaust system consists of three components: front pipe with catalytic converter, intermediate silencer, and rear silencer. Both the intermediate and rear silencers are absorption silencers.

The exhaust system is protected from corrosion with all pipes made of chromium steel. In addition, the silencers are manufactured from corrosion retarding 12-per cent chromium steel plate. The exhaust manifold is cast and is connected to the turbocharger.

The joints are flange (a.k.a. ball-joint) joints. Each has a two-piece clip that is closed with 2 stud bolts and nuts. This facilitates replacement and provides good fit. All joints are without gaskets.

The exhaust system is rubber mounted at seven points. In order to give good ground clearance, the exhaust system is positioned in a floor tunnel.

There are heat shields fitted at points where the heat is most intense. Depending on the position of the shield, they are manufactured from aluminium or zinc plated sheet, and protect the exposed points against heat radiation.

To protect the battery from exposure to heat radiation, the front pipe with primary catalytic converter is equipped with a heat shield.
