Product Information
Fabspeed Supersport X-Pipe (X-Pipe Only).
The Fabspeed Porsche 997.2 Turbo / Turbo S Supersport X-Pipe is a high-performance rear exhaust upgrade designed to replace the heavy and restrictive factory rear mufflers with a freer-flowing X-pipe configuration.

Fits:
  • Porsche 997 MKII Turbo / Turbo S 2010-12


Developed specifically for the Porsche 997.2 Turbo and Turbo S, the Supersport X-Pipe improves the route exhaust gases take through the rear of the vehicle, reducing restriction while delivering a stronger and more refined flat-six exhaust note.

Manufactured from 14–16 gauge CNC mandrel-bent T304L stainless steel, the system combines durability, corrosion resistance and efficient exhaust flow in a direct bolt-on package.

What This Product Does:
The factory rear mufflers are designed to keep exhaust noise within production-car requirements while maintaining refinement.

This inevitably introduces some restriction into the exhaust path.

The Fabspeed Supersport X-Pipe replaces the original rear mufflers with a freer-flowing crossover arrangement designed to improve exhaust-gas movement through the rear of the system.

The upgrade is designed to provide:

  • Improved exhaust flow
  • Reduced rear exhaust restriction
  • Improved performance potential
  • Stronger response throughout the RPM range
  • Moderate increase in exhaust volume
  • More refined performance exhaust tone
  • Enhanced turbocharged flat-six character
  • Reduced dependence on restrictive factory rear mufflers

Replaces The Factory Rear Mufflers:
  • The key function of this X-pipe is to replace the original rear muffler assemblies.
  • Factory mufflers contain internal chambers and sound-control structures that reduce exhaust volume but can also restrict gas flow.
  • Replacing these sections with the Supersport X-Pipe creates a less restrictive route through the rear exhaust system.
  • This makes the product primarily a performance and sound upgrade, although it can also replace deteriorated original rear muffler components where appropriate.

Enhanced Turbo Flat-Six Sound:
Fabspeed describes the Supersport X-Pipe as providing a moderate increase in exhaust volume together with a more refined flat-six tone than the original exhaust.

Drivers can expect:

  • Increased exhaust presence
  • More sporting flat-six tone
  • Stronger sound during acceleration
  • More pronounced character through the RPM range
  • A more engaging turbocharged Porsche exhaust note

The exact sound level will depend on the rest of the exhaust system fitted to the vehicle.

Performance Benefits:
Fabspeed states that the Supersport X-Pipe is designed to improve power throughout the RPM range.

However, the current product listing shows the specific horsepower, torque and weight figures as TBD.

For this reason, exact numerical gains should not be assumed.

Actual performance will depend on factors including:

  • Engine condition
  • Turbocharger condition
  • Existing exhaust configuration
  • Catalytic converters
  • ECU calibration
  • Intake modifications
  • Fuel quality
  • Ambient conditions
  • Vehicle specification

Why Upgrading Matters:
The original rear mufflers do not need to have failed before fitting the Supersport X-Pipe.

This product is primarily a performance and sound upgrade.

Reasons for upgrading include:

  • Freer-flowing rear exhaust design
  • Replaces restrictive factory rear mufflers
  • Improved exhaust flow
  • Improved performance potential
  • Moderate increase in exhaust volume
  • More refined flat-six exhaust tone
  • T304L stainless-steel construction
  • 14–16 gauge tubing
  • CNC mandrel-bent construction
  • Direct bolt-on installation
  • No cutting or welding required
  • Purpose-designed fitment for the 997.2 Turbo and Turbo S

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.

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.
