Fabspeed Exhaust Performance Package WITH XperTune Performance Software.
The Fabspeed Porsche 955 Cayenne S Performance Package is a comprehensive exhaust, intake and ECU performance upgrade designed for the V8-powered Porsche 955 Cayenne S.

Fits:
  • Porsche 955 Cayenne S 4.5L V8 2002-07


Rather than changing only one component, the package combines Maxflo Performance Mufflers with Deluxe Quad Style Tips, Secondary Cat Bypass Pipes, a BMC F1 Replacement Air Filter and a Fabspeed XperTune ECU upgrade. Together, these components are designed to reduce intake and exhaust restriction, improve engine breathing, reduce weight and give the Cayenne S a deeper, throatier and more sporting V8 exhaust note.

The exhaust components are manufactured from 14–16 gauge T304 stainless steel for durability and resistance to heat and corrosion. Fabspeed lists approximately 60 lb of weight reduction compared with the corresponding factory components.


What This Product Does:

  • The Cayenne S engine must draw clean air into the engine and efficiently expel combustion gases through the exhaust.
  • The Fabspeed Performance Package addresses both sides of this process.
  • The BMC F1 Air Filter provides a performance-oriented replacement for the original filter element, supporting improved intake airflow.
  • The Secondary Cat Bypass Pipes replace the factory secondary catalytic converters, reducing restriction in the exhaust system.
  • The Maxflo Performance Mufflers replace the factory rear mufflers with a freer-flowing performance design.
  • The Fabspeed XperTune ECU calibration can optimise selected engine-management parameters to complement the performance hardware.
  • Together, these components provide a coordinated upgrade for airflow, response, exhaust sound and overall performance potential.

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

This is primarily a performance, sound and appearance upgrade.

Reasons for upgrading include:

  • Maxflo Performance Mufflers
  • Secondary Cat Bypass Pipes
  • BMC F1 Replacement Air Filter
  • Fabspeed XperTune ECU software  
  • T304 stainless-steel construction
  • Approx. 60 lb manufacturer-listed weight reduction
  • Reduced intake restriction
  • Reduced exhaust restriction
  • Improved engine breathing
  • Increased performance potential
  • Sharper response
  • Deeper and throatier V8 sound
  • Deluxe Quad Style exhaust tips
  • Choice of tip finishes

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.
