Fabspeed RACE Valved Supersport X-Pipe Exhaust System.

The Fabspeed Porsche 991 Turbo / Turbo S Valved Supersport X-Pipe Exhaust System is a high-performance exhaust upgrade designed to deliver enhanced exhaust sound, improved gas flow and driver-controlled exhaust volume for the Porsche 911 Turbo and Turbo S (991.1), manufactured between 2013 and 2016.

Fits:

• Porsche 991.1 Turbo 3.8L (520 Bhp) 2014-16
• Porsche 991.1 Turbo S 3.8L (560 Bhp) 2014-16  

The standard Porsche 991 Turbo exhaust system is engineered to balance performance, emissions and noise regulations. Although effective for everyday driving, its factory mufflers and catalytic converter arrangement can restrict exhaust sound and reduce the audible character of the turbocharged flat-six engine.

Fabspeed developed the Valved Supersport X-Pipe Exhaust System to provide a more engaging exhaust experience while retaining the flexibility of adjustable sound control.

At the heart of the system is a specially engineered 2.75-inch (70 mm) quad-resonated X-pipe, designed to balance exhaust flow and sound characteristics.

With the exhaust valves closed, gases are directed through the resonated X-pipe, producing a smoother, more controlled exhaust note suitable for lower-noise driving.

When the valves are opened, exhaust gases bypass the resonated X-pipe section, creating a more direct flow path and producing a substantially louder, more aggressive exhaust sound.

This dual-mode configuration allows the driver to enjoy two distinct exhaust characteristics from one system.

Manufactured from 14–16 gauge T304L stainless steel, the exhaust uses CNC mandrel-bent tubing to maintain consistent internal pipe diameter and smooth gas flow.

The system incorporates high-quality Helical vacuum-operated exhaust valves, engineered to withstand the high temperatures and demanding operating conditions associated with turbocharged performance engines.

Available with either high-flow sports catalytic converters or race-only catalytic converter bypass pipes, the system can be configured for different performance requirements and intended applications.

The exhaust is completed with Fabspeed's deluxe quad-style exhaust tips, available in a choice of finishes to complement the Porsche 991 Turbo's rear styling.

Designed as a bolt-on replacement, the system can be installed without cutting or welding, making it a substantial exhaust upgrade for enthusiasts seeking improved sound, performance potential and premium construction.

What This Product Does:
The Fabspeed Valved Supersport X-Pipe replaces the corresponding factory exhaust components with a freer-flowing performance exhaust arrangement.

Its main functions include:

• Improves Exhaust Gas Flow: Uses a performance-oriented pipe layout to reduce unnecessary restrictions within the exhaust system.
• Provides Driver-Controlled Exhaust Sound: Allows switching between two distinct sound characteristics.
• Creates a Refined Closed-Valve Mode: Directs exhaust gases through the quad-resonated X-pipe for a smoother, more subdued exhaust note.
• Delivers an Aggressive Open-Valve Mode: Bypasses the resonated section to produce a louder, more direct exhaust sound.
• Enhances Turbocharged Flat-Six Character: Makes the distinctive exhaust note of the Porsche 3.8L twin-turbocharged engine more prominent.
• Supports Performance Optimisation: Provides an exhaust configuration designed to improve flow and potentially enhance engine response.
• Reduces Exhaust System Weight: Fabspeed lists an approximate 5 lb weight reduction compared with the corresponding factory arrangement.
• Uses High-Flow Stainless Steel Pipework: Mandrel-bent tubing helps maintain consistent exhaust flow through pipe bends.
• Provides Durable Valve Operation: Uses Helical vacuum-actuated valves designed for high-temperature service.
• Enhances Rear Styling: Includes deluxe quad-style exhaust tips.
• Supports Different Vehicle Configurations: Offers valve-control options for vehicles with or without factory Porsche Sport Exhaust.
• Maintains Bolt-On Installation: Designed to fit the corresponding Porsche 991 Turbo application without cutting or welding.

Symptoms Of Wear Or Failure:
The Fabspeed Valved Supersport X-Pipe is primarily a performance upgrade rather than a component that must be replaced at a fixed service interval.

However, deterioration of the original exhaust system or faults within an existing valved exhaust assembly may make replacement or repair necessary.

• Hissing, ticking or blowing noises.
• Increased exhaust volume from an unexpected location.
• Soot deposits around exhaust joints.
• Exhaust fumes around the rear of the vehicle.
• Increased noise during acceleration.
• Visible rust or deterioration.
• Weak or damaged welds.
• Cracked mounting points.
• Perforated pipework.
• Exhaust sections becoming loose or insecure.
• Exhaust sound remaining unchanged when switching modes.
• One exhaust valve operating while the other remains stationary.
• A valve stuck open, causing consistently high exhaust volume.
• A valve stuck closed, preventing the louder operating mode.
• Unusual metallic rattling around the valve assemblies.
• Irregular valve movement.

Why Replacement / Upgrading Matters:
Upgrading to the Fabspeed Valved Supersport X-Pipe can improve the driving experience by combining performance-oriented exhaust flow with adjustable sound control.

• Two Exhaust Sounds in One System: Switches between a more refined resonated mode and a louder performance mode.
• Enhanced Exhaust Character: Brings out the distinctive sound of the Porsche 991 Turbo's twin-turbocharged flat-six engine.
• Improved Exhaust Flow: Uses larger performance-oriented pipework and an optimised flow path.

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.
