Exhaust Package
- Porsche 955 Cayenne Turbo 4.5L 2003-06
- Porsche 955 Cayenne Turbo S 4.5L 2006>>
The Fabspeed Performance Package is a comprehensive exhaust, intake designed for the 2002–2007 Porsche 955 Cayenne Turbo and Turbo S.
Kit Contents:
- Maxflo Performance Mufflers Incl Deluxe Quad Style Tips
- Sport Catalytic Converters
- Secondray Catbypass Pipes
- BMC F1 Air Filter
Fits:
- Porsche 955 Cayenne Turbo 4.5L 2002-06
- Porsche 955 Cayenne Turbo S 4.5L 2006>>
Rather than modifying a single area of the vehicle, the package combines several complementary performance components to improve the way the twin-turbocharged V8 draws in air, expels exhaust gases and manages engine performance.
The package includes Maxflo Performance Mufflers with Deluxe Quad Style Tips, Sport Catalytic Converters, Secondary Cat Bypass Pipes, a BMC F1 Replacement Air Filter.
Together, these components are designed to reduce intake and exhaust restriction, improve engine breathing, sharpen response, reduce weight and produce a deeper, throatier V8 exhaust note.
The Fabspeed exhaust components are manufactured from 14–16 gauge mirror-polished T304 stainless steel, and Fabspeed lists approximately 60 lb of weight reduction compared with the corresponding factory components.
What This Product Does:
An internal-combustion engine must efficiently draw in clean air and expel combustion gases.
This becomes especially important in a high-output twin-turbocharged engine, where both the intake and exhaust systems must handle substantial airflow under load.
The Fabspeed package addresses several areas simultaneously:
- BMC F1 Air Filter – improves intake airflow while maintaining engine filtration.
- Sport Catalytic Converters – provide a performance-oriented alternative to the original catalyst arrangement.
- Secondary Cat Bypass Pipes – eliminate the secondary catalytic converters to further reduce exhaust restriction.
- Maxflo Performance Mufflers – improve rear exhaust flow while creating a deeper V8 exhaust note.
The result is a coordinated performance package rather than a single-component upgrade.
Performance:
The current Fabspeed product listing specifies:
Horsepower: TBD
Torque: TBD
Weight Reduction: Approx. 60 lb
Because package-specific horsepower and torque figures are currently listed as TBD, numerical power gains should not be assumed.
Actual performance will depend on factors including:
- Engine condition
- Turbocharger condition
- Fuel quality
- Intake condition
- Exhaust configuration
- Other modifications
- Ambient conditions
- Testing equipment and methodology
Why Upgrading Matters:
The original components do not need to be faulty or worn before this package is installed.
It is primarily a comprehensive performance upgrade.
Reasons for upgrading include:
- Maxflo Performance Mufflers
- Sport Catalytic Converters
- Secondary Cat Bypass Pipes
- BMC F1 Replacement Air Filter
- 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 twin-turbo V8 sound
- Deluxe Quad Style polished exhaust tips

Exhaust System Packages for Porsche | Performance, Precision & Sound
A well-designed exhaust system package is essential for maintaining your Porsche’s performance, efficiency, and distinctive exhaust tone. These complete systems replace worn or restrictive exhaust components with precision-engineered, high-flow assemblies that restore or enhance power delivery and sound quality.
At Design911, we offer a comprehensive selection of exhaust system packages for Porsche models — from classic 911s to modern GT-series vehicles. Each package includes key components such as silencers, manifolds, catalytic converters, and pipework, designed for optimal gas flow, reduced back pressure, and improved throttle response.
Manufactured from premium stainless steel, Inconel, or titanium, our exhaust kits are built for durability, corrosion resistance, and superior acoustic performance. Whether you’re restoring a vintage air-cooled model or tuning your track-ready GT3, these exhaust systems deliver a perfect balance of reliability, performance, and sound.
What Do Exhaust System Packages Do?
An exhaust system package channels exhaust gases away from the engine efficiently while controlling noise and emissions. A properly designed system ensures optimal engine breathing — improving power, torque, and overall efficiency.
Core Functions:
- Directs
exhaust gases safely from the engine.
- Reduces
back pressure to maximise power output.
- Controls
emissions via catalytic converters and mufflers.
- Enhances
exhaust tone for an authentic Porsche sound.
- Optimises gas flow for performance and reliability.
An upgraded exhaust system can also provide weight reduction, improved throttle response, and enhanced driving enjoyment.
Why Do Exhaust Systems Fail?
Over time, even the most durable exhaust systems deteriorate due to constant exposure to heat, vibration, and the elements.
Common Causes of Exhaust System Failure Include:
Corrosion
and rust, especially on mild steel systems.
When exhaust components fail, you may notice rattling sounds, loss of performance, strong fumes, or increased fuel consumption — all signs that replacement is needed.
Why Replace or Upgrade Your Exhaust System?
Replacing or upgrading your Porsche’s exhaust system ensures maximum performance, efficiency, and driving enjoyment.
Key Benefits:
- Restores optimal gas flow and back pressure.
- Improves horsepower and torque.
- Enhances sound and throttle response.
- Reduces weight for improved handling.
- Prevents leaks and emissions issues.
- Crafted from corrosion-resistant, high-grade materials.
- Direct-fit design for Porsche 911, Cayman, Boxster, Panamera, Macan and more.
Whether for performance tuning, restoration, or replacement, Design911’s exhaust system packages deliver the sound, precision, and reliability Porsche owners expect.
Highlights:
- Complete exhaust system packages for all Porsche models.
- Includes manifolds, silencers, catalytic converters, and pipes.
- Manufactured from stainless steel, Inconel, or titanium.
- Engineered for maximum performance and sound.
- Precision-fit designs for simple installation.
