Exhaust manufacturer Milltek has released details of its hand-finished stainless steel exhaust system for the Porsche Panamera Turbo.

Milltek kept the dual personality that Porsche has carefully engineered into the car. Their new system offers a relaxed and refined demeanour for motorway cruising, balanced with a superbly sporty growl under load and when driving hard. The system is based around the high quality non-magnetic stainless steel and uses a consistent 70mm bore and CNC mandrel bends for optimum flow.

The Milltek system bolts directly to the factory catalysts and deletes the centre silencers to maximise gasflow. During testing, this design was found to reduce back pressure from 250 millibars to just 60. Custom-formed endplates and teardrop-section silencers at the rear of the vehicle enhance the harmonics of the system.

The use of active valves is the secret to the Milltek’s ‘Jekyll and Hyde’ persona. Cruising off the throttle sees the valves shut, resulting in factory noise levels and a lack of cabin resonance. However, should the mood take you to drive a little more ‘enthusiastically’, the valves will open accordingly, allowing the Panamera to breathe more freely.

Two versions are available and both fit both the Turbo and Turbo S variants of the Panamera. The Cup system offers maximum performance, whilst the forthcoming Euro system will be fully homologated and appropriately accredited. Both offer the ability to handle a proven 700bhp with ease. You can opt for 100mm GT trim tips in Ink Black, mirror polished or Titanium.
