Fabspeed Exhaust Sport Performance Package, WITH XperTune Performance Software. Porsche 958 Turbo / Turbo S (2011-2014)  ❭  FSPOR958TSPKGE

Fabspeed Exhaust Sport Performance Package, WITH XperTune Performance Software.
The Fabspeed Porsche 958 Cayenne Turbo / Turbo S Sport Performance Package is a comprehensive exhaust and intake upgrade designed to improve exhaust flow, engine breathing, throttle response and sound on 2011–2014 Porsche 958 Cayenne Turbo and Turbo S models.

Fits:

• Porsche 958 Cayenne Turbo V8 4.8L Petrol (500Hp) 2011-14
• Porsche 958 Cayenne Turbo S V8 4.8L Petrol (550Hp) 2011-14

Rather than upgrading a single component, the package combines several complementary performance parts to improve both the intake and exhaust sides of the twin-turbocharged V8.

The package includes Fabspeed Maxflo Performance Mufflers with Deluxe Quad Style Tips, Secondary Link/Cat Bypass Pipes and BMC F1 replacement air filters, with Fabspeed performance ECU software.

The exhaust components are manufactured from 14–16 gauge CNC mandrel-bent polished T304 stainless steel, providing a durable performance-oriented replacement for restrictive factory exhaust components.

What This Product Does:
The package is designed to help the Cayenne Turbo's engine move air into and out of the engine more efficiently.

The BMC F1 air filters improve the intake side by replacing the standard paper filter elements with performance-oriented filters.

The Secondary Cat Bypass Pipes reduce restriction in the exhaust by replacing the secondary catalytic converter sections.

The Maxflo Performance Mufflers replace the restrictive factory rear exhaust components and provide a freer-flowing exhaust path.

The ECU performance software modifies engine-management calibration to complement the hardware upgrades.

The combined package is designed to provide:

• Improved exhaust flow
• Reduced exhaust restriction
• Improved intake airflow
• Sharper throttle response
• Increased performance potentia
• lDeeper exhaust tone
  
• More pronounced turbo V8 sound
• Sportier rear appearance
• Improved overall driving character

Performance:
Fabspeed currently lists the package figures as:

Horsepower: TBA
Torque: TBA
Weight: TBA

No specific numerical performance or weight-saving figures should therefore be assumed for this package.

Actual results will vary according to:

• Vehicle condition
• Turbocharger condition
• Fuel quality
• ECU calibration
• Intake configuration
• Exhaust configuration
• Ambient conditions
• Testing equipment
• Testing methodology

Why Upgrading Matters:
The factory components do not need to have failed before installing this package.

This is primarily a comprehensive performance, sound and appearance upgrade.

Reasons for upgrading include:

• Complete intake and exhaust package
• Maxflo Performance Mufflers
• Secondary Cat Bypass / Link Pipes
• BMC F1 replacement air filters
• Deluxe Quad Style Tips
• Optional ECU performance software  
• 14–16 gauge T304 stainless-steel construction
• CNC mandrel-bent exhaust tubing
• Reduced exhaust restriction
• Improved intake airflow
• Improved throttle response
• Increased performance potential
• Deeper turbo V8 exhaust note
• More performance-oriented rear styling

Installation:
Fabspeed describes the package as a bolt-on installation but specifies that minor cutting is required at the factory exhaust break point, using the OEM dimple locations as a reference.

This means the installation should not be described as completely cutting-free.

Before installation, inspect:

• Factory exhaust tubing
• Exhaust mounting points
• Clamps and hardware
• Exhaust hangers
• Intake housings
• Air-filter housings
• Nearby heat shielding
• Wiring and hoses

Professional installation is recommended to ensure correct exhaust alignment, secure connections and adequate clearance.
