Fabspeed Exhaust

The factory exhaust system uses catalytic converters to treat exhaust gases before they leave the vehicle.

Although catalytic converters perform an important emissions-control function, they also create some resistance to exhaust flow.

The Fabspeed Cat Bypass Pipes remove this catalyst section entirely and replace it with straight-through stainless-steel tubing.

Their purpose is to provide:

• Increased exhaust flow
• Reduced exhaust restriction
• Improved throttle response
• Increased performance potential
• Reduced exhaust-system weight
• Increased exhaust volume
• More noticeable turbocharger spool
• More aggressive flat-six exhaust sound

These characteristics make the pipes primarily suited to track and competition vehicles where maximum exhaust flow is prioritised over road-going emissions compliance.

When Might Cat By-Pass Pipes Be Considered:
These pipes are not conventional replacement catalytic converters.

They are a track-focused performance modification intended to remove the catalytic-converter section completely.

They may be considered when:

• Building a closed-course track vehicle
• Maximum exhaust flow is desired
• A more aggressive exhaust note is wanted
• Increased turbo spool sound is desired
• Reduced exhaust-system weight is important
• The vehicle is being modified for competition use
• Other compatible performance upgrades are being installed

For a road-going vehicle, catalytic converters should not simply be removed as a replacement for failed components.

Why Replacement Matters:
A damaged or internally collapsed catalytic converter can restrict exhaust flow.

This can lead to:

• Reduced engine performance
• Poor throttle response
• Increased exhaust backpressure
• Excessive exhaust temperatures
• Engine-management faults
• Poor acceleration

On a road-going vehicle, the correct solution is normally to diagnose the cause and replace a failed catalytic converter with an appropriate emissions-compliant component.

For a dedicated track or off-road vehicle, Fabspeed Cat Bypass Pipes provide an alternative performance configuration that removes the catalysts and maximises exhaust flow.

Exhaust tips form the visible final outlets of the exhaust system.

Although they do not perform the same gas-treatment or silencing functions as catalytic converters and mufflers, they provide the finishing point through which exhaust gases exit at the rear of the vehicle.

The Fabspeed Deluxe Quad Style Tips are primarily designed to:

• Replace the factory exhaust outlets
• Provide a sportier quad-tip appearance
• Improve the visual finish of the rear bumper area
• Give the Porsche a more aggressive performance look
• Provide durable stainless-steel exhaust outlets
• Replace scratched, corroded or damaged original tips
• Complement Fabspeed and other compatible performance exhaust upgrades

Common signs of deterioration include:

• Surface corrosion
• Heavy discoloration
• Persistent staining
• Scratches
• Dents
• Cracks
• Bent outlets
• Damaged mounting points
• Loose exhaust tips
• Excessive movement
• Poor alignment
• Peeling or damaged finish
• Heavy carbon and soot deposits
• Tips sitting unevenly within the bumper openings

Cosmetic deterioration does not necessarily affect exhaust-system performance, but physical damage or loose mounting should be corrected.

Why Replacement Matters:
Unlike a catalytic converter, muffler or exhaust pipe, a worn exhaust tip will not normally cause a major loss of engine performance.

Replacement matters primarily for appearance, fitment and physical condition.

Replacing worn or damaged tips can:

• Restore the rear appearance of the vehicle
• Remove heavily scratched or corroded outlets
• Correct bent or damaged tips
• Restore proper exhaust outlet alignment
• Eliminate rattling from damaged or loose tips
• Provide a more aggressive quad-tip appearance
• Complement other exhaust upgrades
• Refresh the appearance of an ageing Porsche

For a well-maintained performance car, details such as exhaust outlets can make a substantial difference to the overall presentation of the vehicle.

Catalytic converters form an important part of the vehicle's exhaust and emissions-control system.

Exhaust gases leaving the turbochargers pass through the catalytic converters before travelling through the remainder of the exhaust system. The catalyst promotes chemical reactions that convert harmful exhaust pollutants into less harmful gases before they leave the exhaust.

Performance catalytic converters perform the same fundamental role but use a less restrictive internal structure to improve exhaust flow.

The Fabspeed Sport Cats are designed to provide:

• Increased exhaust flow
• Reduced exhaust restriction
• Improved power
• Improved torque
• Sharper throttle response
• Increased performance potential
• More noticeable flat-six exhaust sound
• Reduced exhaust-system weight
• Continued catalytic exhaust-gas treatment

Common symptoms can include:

• Check-engine warning light
• Catalyst-efficiency fault codes
• Reduced engine performance
• Poor throttle response
• Restricted exhaust flow
• Unusual rattling from underneath the vehicle
• Excessive exhaust heat
• Sulphur-like or unusual exhaust smell
• Poor acceleration
• Increased fuel consumption
• Failed emissions testing
• Visible damage to the catalytic converter
• Abnormal exhaust noise

A failed catalyst should be properly diagnosed before replacement.

Why Replacement Matters:
A damaged, contaminated or internally collapsed catalytic converter can restrict exhaust flow and interfere with engine performance.

Possible consequences include:

• Reduced power
• Poor acceleration
• Increased exhaust backpressure
• Excessive exhaust heat
• Engine-management warning lights
• Emissions faults
• Increased fuel consumption
• Further damage to exhaust components

Replacing a failed converter restores the intended exhaust path and catalytic function.

When upgrading to Fabspeed Sport Catalytic Converters, replacement can additionally provide reduced exhaust restriction, improved throttle response, increased performance potential and a sportier exhaust sound.

The exhaust system carries hot combustion gases away from the turbochargers and through the rear of the vehicle.

On a turbocharged engine, reducing unnecessary restriction after the turbochargers can improve exhaust flow and help the complete engine and turbo system operate more efficiently.

The Fabspeed Supersport X-Pipe replaces restrictive factory exhaust components with a freer-flowing performance design.

Its purpose is to provide:

• Improved exhaust-gas flow
• Reduced exhaust restriction
• Improved power potential
• Stronger performance throughout the RPM range
• More noticeable turbo spool sound
• A deeper and sportier flat-six exhaust note
• Reduced exhaust-system weight
• More aggressive rear styling
• Improved driving character

It may be considered when:

• More exhaust sound is desired
• Improved turbo sound is wanted
• The factory exhaust feels too restrictive
• A freer-flowing performance exhaust is required
• Increased performance potential is desired
• Reduced exhaust-system weight is beneficial
• A more aggressive rear appearance is wanted
• The original mufflers or catalytic converters are damaged
• The vehicle is being prepared for further performance upgrades

Exhaust leaks can allow extremely hot gases to escape before reaching the intended outlet.

Depending on the location and severity of the fault, this may cause:

• Excessive exhaust noise
• Exhaust fumesSoot deposits
  
• Heat damage to surrounding components
• Reduced exhaust-system efficiency
• Incorrect oxygen-sensor readings
• Engine-management faults
• Poor exhaust sealing

Replacing deteriorated components restores the integrity of the exhaust system.

For owners choosing the Fabspeed Supersport system as an upgrade, replacement also provides an opportunity to improve exhaust flow, reduce weight and significantly enhance the sound of the 997.2 Turbo or Turbo S.

Designed to optimise the factory engine-management system, XperTune recalibrates key ECU parameters to increase horsepower and torque while improving throttle response, boost performance and overall driving characteristics.

Unlike traditional ECU tuning methods that may require the control unit to be removed and sent away for bench flashing, the Fabspeed system uses an included handheld tuner connected through the vehicle's OBD-II diagnostic port. This allows the original ECU data to be read and a custom Fabspeed tune to be installed without physically removing the ECU.

What This Product Does:
The engine control unit, or ECU, manages many of the operating parameters that determine how the engine performs.

Fabspeed's XperTune software changes selected ECU calibration parameters to optimise the performance of the twin-turbocharged 3.8L engine.

According to Fabspeed, the software modifies areas including:

• Sensor inputsAir/fuel ratios
  
• Boost pressure where applicable
• Engine performance calibration
• Power and torque delivery
• Driving characteristics

The objective is to extract additional performance from the engine while maintaining usable everyday drivability.

How Does The XperTune Process Work:
The supplied handheld tuner communicates directly with the Porsche through its OBD-II port.

The process involves:

• Connecting the handheld tuner to the vehicle.
• Reading the factory ECU data through the OBD-II port.
• Connecting the handheld device to a Windows computer.
• Sending the original vehicle data and relevant vehicle information to Fabspeed.
• Fabspeed creates a custom tune based on the vehicle's setup.
• The custom tune file is returned electronically.
• The tune is transferred onto the handheld device.
• The handheld is reconnected to the Porsche.
• The new calibration is written to the ECU.

This avoids the normal requirement to remove the ECU and physically ship it away for tuning.

When Might XperTune Be Worth Considering:

• The Fabspeed XperTune software may be suitable when:
• Increased horsepower is desired
• Increased torque is wanted
• Sharper throttle response is required
• Stronger acceleration is desired
• Compatible exhaust upgrades have been installed
• Compatible intake modifications have been fitted
• ECU calibration matched to vehicle modifications is requiredAn OBD-II tuning solution is preferred
  
• The owner wants the ability to restore the factory calibration
