Fabspeed Supersport STREET Performance Exhaust Package.

The Fabspeed Supersport STREET Performance Package is a comprehensive performance upgrade designed for the 2013–2016 Porsche 991 Turbo and Turbo S.

Fits:

  • Porsche 991.1 Turbo 3.8L (520 Bhp) 2013-16
  • Porsche 991.1 Turbo S 3.8L (560 Bhp) 2013-16  

Rather than upgrading a single component, the package combines freer-flowing exhaust hardware, performance headers, improved intake filtration and ECU software to enhance the overall breathing and response of the twin-turbocharged 3.8-litre engine.

The package includes:

  • Fabspeed Supersport X-Pipe Exhaust System
  • 200-cell HJS Sport Catalytic Converters
  • Fabspeed Sport Headers
  • BMC F1 Replacement Air Filter
  • Fabspeed XperTune Performance Software with handheld tuner
  • Choice of Deluxe Quad-Style or GT2-Style exhaust tips

Fabspeed quotes gains of approximately 83 horsepower and 127 lb-ft of torque, together with a 15 lb reduction in weight. Actual results can vary depending on vehicle condition, fuel, specification and operating conditions.

What This Product Does:
The package improves several areas that affect engine airflow and turbocharger performance.

The factory intake and exhaust systems must balance refinement, noise control, emissions requirements and performance. The Fabspeed package uses less restrictive components and matching engine-management software to increase airflow and allow the engine to take greater advantage of the upgraded hardware.

Its main benefits include:

  • Improved exhaust gas flow
  • Reduced post-turbo exhaust restriction
  • Improved throttle response
  • Shorter turbo spool time
  • Quicker acceleration
  • Increased horsepower and torque
  • More pronounced sports-car exhaust sound
  • Reduced exhaust-system weight
  • Improved intake airflow
  • ECU calibration designed around the performance upgrades

Symptoms Of Wear Or Failure:
Because this package replaces or upgrades several systems, symptoms vary depending on the component affected.

  • Exhaust blowing, ticking or hissing
  • Cracked pipes or welds
  • Black soot around leaking joints
  • Metallic rattling from catalytic converters
  • Reduced engine performance
  • Increased turbo lag
  • Restricted exhaust flow
  • Check Engine Light relating to catalyst efficiency
  • Unusual sulphur-like exhaust smell
  • Corroded or damaged exhaust components

Why Replacement / Upgrading Matters:
The Porsche 991 Turbo relies on efficient airflow both before and after its turbochargers.

A restricted intake makes it harder for the engine to draw the air it needs, while excessive exhaust restriction works against efficient evacuation of gases after combustion.

Deteriorated catalysts, leaking headers or damaged exhaust components can therefore contribute to:

  • Slower turbo response
  • Reduced performance
  • Increased exhaust temperatures
  • Poor throttle response
  • Exhaust leaks
  • Increased mechanical and thermal stress

Replacing deteriorated components restores the integrity of these systems.

For a vehicle with healthy factory components, the Fabspeed package is primarily a performance upgrade, combining intake, exhaust and ECU modifications as one integrated system rather than upgrading each component independently.

About Exhaust Package

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.

  • Cracks or leaks caused by vibration and thermal stress.
  • Worn gaskets or clamps leading to exhaust leaks.
  • Clogged catalytic converters reducing flow and performance.
  • Broken hangers or mounts causing misalignment.

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.
