DOES MY CAR HAVE "PSE"?


The Porsche Sport Exhaust – better known as PSE – was a factory option available on many late model Porsches. You can quickly and easily determine if your vehicle is equipped with PSE by taking a look at your center console. If your console has a button on it with an "exhaust tip" icon (see photo), then your vehicle is equipped with PSE, and you should select the PSE option when adding this product to your cart. If you do not see this button, the your vehicle does not have PSE and you should select the standard exhaust option when checking out.

Please note: This is a special-order item manufactured to order. In some cases, please allow 4 – 5 weeks for the delivery. Special order items cannot be cancelled from this supplier once your order has been placed.

About Fabspeed Exhaust

Fabspeed Exhaust Systems - Precision Performance & Sound Upgrades

Fabspeed Exhaust Systems are premium performance exhaust upgrades engineered to deliver increased power, improved exhaust flow, and a distinctive motorsport-inspired sound. Designed and manufactured with precision engineering and performance testing at their core, Fabspeed exhausts are built to enhance the driving experience of Porsche road and track vehicles alike.

Available from Design911, Porsche Fabspeed exhaust components are crafted using high-quality stainless steel and optimised designs to reduce backpressure, improve throttle response, and unleash a more engaging exhaust tone while maintaining durability and reliability.

What Do Fabspeed Exhaust Systems Do?

Fabspeed exhausts optimise exhaust gas flow and acoustic performance.

Core Functions:

  • Reduce exhaust restriction and backpressure.
  • Improve throttle response and power delivery.
  • Enhance exhaust sound and character.
  • Improve engine efficiency and breathing.
  • Upgrade exhaust aesthetics and build quality.

A high-flow exhaust system plays a key role in unlocking engine performance.

Why Do Standard Exhaust Systems Fail or Limit Performance?

Factory exhaust systems are designed to prioritise emissions compliance, cost efficiency, and sound suppression. Over time, they can suffer from:

  • Restrictive internal baffling reducing performance.
  • Corrosion from moisture and repeated heat cycles.
  • Excessive weight limiting efficiency.
  • Muted exhaust sound lacking engagement.
  • Reduced compatibility with performance tuning upgrades.

As engines are pushed harder, standard exhausts can become a performance bottleneck.

Upgrade Benefits:

  • Improved exhaust flow for increased performance.
  • Sportier, more aggressive exhaust sound.
  • Lightweight, durable stainless steel construction.
  • Precision-engineered components for perfect fitment.
  • Ideal for performance road cars and track applications.

Upgrading to Fabspeed delivers noticeable gains in sound, response, and driving excitement.
