Exhaust system for the 3.0l TFSI engine
The gas flow paths are very short because the turbocharger
module is located in the inner V of the engine.
Catalytic converter module
The module is flanged-mounted directly to the exhaust turbocharger, which
houses the main and secondary catalytic converters. Both catalytic convert-
ers are ceramic-type converters.
Center muffler (operates on
the absorption principle)
Decoupling element
Front muffler (operates on the
absorption principle)
Main catalytic converter
Secondary catalytic converter
The catalytic converter is bolted directly to the exhaust
turbocharger outlet. This allows the catalytic converter to
reach its optimal operating temperature very quickly after a
cold start.
