Exhaust System

Exhaust system

A special exhaust system made of long-life stainless steel is used for the new Panamera V6.










The twin-branch exhaust system with 3-way catalytic converters has a common center muffler two common intermediate mufflers and a rear muffler on the left and right.

The exhaust systems of the Panamera V6 models feature additional center mufflers, which contribute to optimizing the sound in the passenger compartment while at the same time still allowing the typical Porsche sound.

The branch coupling connection on the V6 is located in intermediate muffler 2. This is advantageous for the torque in the low rpm range less than 2,000 rpm (it is located in the center muffler on the V8).

In contrast to the twin-tailpipe look of the S models, the Panamera and Panamera 4 have one oval tailpipe each on the left and right in a unique design.

Exhaust manifold / catalytic converter







To keep emissions low in the cold start phase in particular, it is important that the catalytic converter reaches its optimal operating temperature quickly. For this reason, the exhaust manifolds of all Panamera models are very short so that the high exhaust gas temperature can be used to heat the catalytic converters. This allows the highly-efficient primary and main catalytic converters to heat up quickly and guarantee effective emission control. The 3-way cascade catalytic converters on the left and right each contain one primary and one main catalytic converter. The cylinder bank-specific LSU oxygen sensors ahead of the catalytic converter and LSF oxygen sensors behind the catalytic converter signal the exhaust gas composition to the DME control unit. The DME control unit can then use this information for targeted intervention in bank-specific mixture control. This ensures that the strictest emission standards are met or even bettered.







Emission standard

The V6 models comply with the LEV emission standard in the USA and Canada.
