Fabspeed Exhaust Performance Package WITHOUT ECU Upgrade.
The Fabspeed Performance Package is a comprehensive exhaust, intake designed for the 2008–2010 Porsche 957 Cayenne S and Cayenne GTS.

Kit Contents:
  • Maxflo Performance Mufflers Incl Deluxe Quad Style Tips
  • Secondary Catbypass Pipes
  • BMC F1 Air Filter

Fits:
  • Porsche 957 Cayenne S / GTS 4.8L 2008-10  

Rather than modifying a single component, this package upgrades several areas that influence engine breathing, exhaust flow, response and sound. It combines Maxflo Performance Mufflers with Deluxe Quad Style Tips, Secondary Cat Bypass Pipes, a BMC F1 Replacement Air Filter.

Together, these components are designed to reduce intake and exhaust restriction, improve engine response, reduce weight and give the naturally aspirated V8 a deeper, throatier and more sporting exhaust character.

The Fabspeed exhaust components are manufactured from 14–16 gauge CNC mandrel-bent polished T304 stainless-steel tubing, while Fabspeed lists approximately 60 lb of weight reduction compared with the corresponding factory components.

What This Product Does:
An engine must draw air into the cylinders efficiently and expel combustion gases through the exhaust system.

Restrictions on either side can influence engine breathing and response.

The Fabspeed package addresses the intake, exhaust and engine-management systems together.

  • BMC F1 Air Filter – replaces the factory paper filter element with a performance-oriented replacement designed to improve intake airflow.
  • Secondary Cat Bypass Pipes – replace the factory secondary catalytic converters to reduce exhaust restriction and weight.
  • Maxflo Performance Mufflers – replace the factory rear mufflers with a freer-flowing performance design.

Together, these components create a coordinated performance upgrade for the Cayenne S / GTS.

Why Upgrading Matters:
The original components do not need to be worn or faulty before installing this package.

It is primarily a performance, sound and appearance upgrade.

Reasons for upgrading include:

  • Maxflo Performance Mufflers
  • Secondary Cat Bypass Pipes
  • BMC F1 Replacement Air Filter
  • T304 stainless-steel exhaust construction
  • CNC mandrel-bent tubing
  • Approx. 60 lb manufacturer-listed weight reduction
  • Reduced intake restriction
  • Reduced exhaust restriction
  • Improved engine breathing
  • Increased performance potential
  • Sharper response
  • Deeper V8 exhaust sound
  • Deluxe Quad Style polished exhaust tips

NOTE: In the United Kingdom, sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001. They are not MOT compliant and cannot be used on public roads. These components are intended solely for race and track use.

For vehicles manufactured before 1st March 2001, a non-type approved sports catalytic converter may be fitted, provided it offers comparable performance to the original and the vehicle continues to meet the applicable emissions standards for its age. The vehicle must still pass an MOT test.

If you are located outside the UK, please check your local laws and regulations to ensure compliance.

About All Silencers / Mufflers

Standard Exhaust Systems – Engineered for Performance, Sound & Longevity

A standard exhaust system is essential for your Porsche’s performance, efficiency, and sound. It controls the flow of exhaust gases from the engine, reduces emissions, manages noise levels, and ensures balanced back pressure for optimal power delivery.

At Design911, we supply standard exhaust systems built from high-grade stainless steel and corrosion-resistant materials. Designed to meet or exceed manufacturer performance standards, these systems deliver the perfect blend of durability, refinement, and performance — ideal for both daily driving and restoration projects.

Each exhaust system is developed to ensure precise fitment, excellent gas flow, and an authentic Porsche exhaust note that retains the car’s original character.

What Do Standard Exhaust Systems Do?

A standard exhaust system performs several vital roles that keep your Porsche running efficiently, cleanly, and safely.

Core Functions:

  • Directs exhaust gases safely away from the engine.
  • Reduces emissions through catalytic converters and silencers.
  • Controls back pressure for balanced performance and fuel efficiency.
  • Minimises engine noise while preserving Porsche’s signature tone.
  • Aids temperature regulation and exhaust scavenging.

A properly maintained exhaust system ensures smooth performance, reduced fuel consumption, and compliance with emissions regulations.

Why Do Exhaust Systems Fail?

Exhaust systems are constantly exposed to heat, moisture, and corrosive gases — all of which take a toll over time.

Common Causes of Failure Include:

  • Corrosion and rust from road salt, condensation, and moisture.
  • Cracked welds or pipes due to vibration and thermal cycling.
  • Internal baffle damage causing rattling or loss of silencing effect.
  • Blocked or leaking joints leading to reduced performance and increased noise.
  • Burnt-out catalytic converters or mufflers reducing efficiency.

Signs of exhaust failure include loud noises, rattling, exhaust odours, or reduced engine performance — all clear indicators that replacement is required.

Why Replace Standard Exhaust Components?

Replacing a worn or damaged exhaust system restores performance, comfort, and efficiency while maintaining your Porsche’s distinctive exhaust tone.

Key Benefits:

  • Restores proper exhaust flow and back pressure.
  • Improves fuel efficiency and power output.
  • Reduces noise and vibration.
  • Ensures emissions compliance and MOT readiness.
  • Built from corrosion-resistant stainless steel for longevity.
  • Direct-fit compatibility for classic and modern Porsche models.

Upgrading to a high-quality standard exhaust preserves the car’s original performance characteristics while ensuring long-lasting reliability.

Highlights:

  • Precision-engineered exhaust systems for Porsche vehicles.
  • Optimised gas flow for power, torque, and efficiency.
  • Durable stainless-steel construction for corrosion resistance.
  • Designed for authentic tone and perfect fitment.
  • Suitable for classic restoration and modern maintenance.
  • Reliable, quiet, and performance-balanced solutions.
