This stunning system is constructed entirely from lightweight high-grade titanium. Its beautiful and sleek design is finished with a central muffler with two pairs of eye-catching double round tailpipes – available in either handmade carbon fibre or sandblasted and coated titanium for increased durability – and it incorporates exhaust-valve housings cast in the Akrapovič in-house foundry. The sound has been tuned to deliver a fulfilling acoustic statement every time the car fires to life. The Evolution Line (Titanium) produces a deep, strong growl from the V8 turbo engine, giving the driver and passengers a true feeling of the immense torque the engine has to offer. This is achieved through a carefully designed X-crossing element in the link pipes that influences the sound. This allows the exhaust gases to mix from both sides of the engine, placing the resulting combination on par with a finely tuned musical instrument and creating incredible high-frequency overtones as the revs rise, all without any compromise to aural clarity and comfort. Fully ECE-compliant and with a simple plug-and-play installation, with no need to remap the ECU, the Evolution Line (Titanium) also adds increased performance to the stunning visual appeal. Test gains achieved by the Akrapovič technicians in controlled conditions show both power and torque gains over the Porsche sport exhaust system of +8.2 kW at 5,600 rpm and +16.6 Nm at 2,400 rpm, respectively, making the system an impressive addition to the Porsche Cayenne Turbo (536).

The sound can be further controlled with the addition of the optional Akrapovič Sound Kit, which offers increased operational features over the exhaust system. When fitted with the optional Akrapovič Sound Kit, ECE type approval is no longer valid.

ECE type approval is only valid for cars equipped with otto/gasoline particulate filter.

About Switchable Silencers / Mufflers

Porsche Switchable Silencers & Mufflers - Dual-Mode Performance Exhaust Systems

Switchable Silencers / Mufflers offer Porsche owners the best of both worlds—refined, road-friendly exhaust sound when cruising, and an aggressive, performance-focused tone at the touch of a button. Using valve-controlled technology, these exhaust systems allow drivers to switch between quiet and sport modes, delivering enhanced sound, performance, and driving engagement on demand.

Available from Design911, Porsche switchable silencers include both genuine Porsche-engineered systems and high-quality aftermarket performance options, all designed to integrate seamlessly with your vehicle’s existing exhaust components and control systems.

What Do Switchable Silencers / Mufflers Do?

Switchable silencers use internal exhaust valves to control sound level and exhaust flow.

Core Functions:

  • Allow selectable quiet and sport exhaust modes.
  • Improve exhaust gas flow under performance driving.
  • Enhance throttle response and engine efficiency.
  • Maintain refined sound levels for everyday driving.
  • Deliver a more engaging driving experience on demand.

These systems adapt your Porsche’s character to suit any driving situation.

Why Do Standard Exhaust Silencers Fail or Fall Short?

Factory exhaust systems are designed to meet noise regulations and long-term durability requirements, which can limit performance and sound. Common issues include:

  • Internal corrosion from heat and condensation.
  • Restrictive baffling reducing exhaust flow.
  • Fixed sound levels with no adaptability.
  • Valve or actuator wear in older switchable systems.
  • Limited performance compatibility with tuned engines.

Over time, standard silencers may lose efficiency, sound quality, or reliability.

Why Upgrade to Switchable Silencers / Mufflers?

Upgrading to a switchable exhaust system enhances both performance and versatility.

Upgrade Benefits:

  • Dual-mode exhaust sound at the press of a button.
  • Improved exhaust flow for better performance.
  • Sportier, more engaging exhaust note when desired.
  • Maintains comfort and compliance in quiet mode.
  • Ideal for road, touring, and spirited driving.

Whether OEM or aftermarket, switchable silencers offer flexibility without compromise.

Highlights

  • Porsche switchable silencer and muffler upgrades
  • Valve-controlled exhaust sound adjustment
  • OEM Porsche and premium aftermarket options
  • Improved performance, sound, and driving engagement
  • Compatible with factory systems and controls
