Fabspeed RACE Sport Exhaust Performance Package PSE, WITH Performance Software, Polished Stainless Steel Tips.
The Fabspeed Performance Package is a comprehensive intake and exhaust upgrade designed for Porsche 991 Carrera models from 2012–2016.

Fits:

  • Porsche 991.1 Carrera C2 3.4L (350 Bhp) 2012-16
  • Porsche 991.1 Carrera C2S / GTS 3.8L (400/430 Bhp) 2012-16
  • Porsche 991.1 Carrera C4 3.4L (350 Bhp) 2012-16
  • Porsche 991.1 Carrera C4S / GTS 3.8L (400/430 Bhp) 2012-16  

Rather than replacing a single exhaust component, the package combines headers, centre exhaust, side mufflers, intake filters and optional / required tuning depending on configuration to improve exhaust flow, throttle response, sound and overall engine performance.

Package Includes:

  • Fabspeed Race Headers with catalytic-converter bypass
  • Valvetronic Center Muffler Bypass X-Pipe
  • Maxflo Performance Side Mufflers
  • BMC F1 Replacement Air Filters
  • XperTune Performance Software required by Fabspeed for this configuration


The system is designed to provide a deeper, more aggressive flat-six exhaust note while improving airflow through both the intake and exhaust systems.

What This Product Does:
The factory Porsche exhaust and intake systems are designed to balance performance, noise control, emissions and everyday refinement.

The Fabspeed package reduces restriction in several areas simultaneously.

Its main functions and benefits include:

  • Improving exhaust gas flow
  • Reducing restriction in the factory side and centre mufflers
  • Improving flow through the exhaust headers
  • Increasing intake airflow with BMC filters
  • Improving throttle response
  • Increasing horsepower and torque
  • Producing a stronger sports-car exhaust note
  • Reducing exhaust-system weight
  • Allowing quieter and louder exhaust characteristics depending on valve position
  • Providing a complete matched performance package rather than isolated modifications

Performance Benefits:
Fabspeed's current published dyno data shows gains throughout the RPM range.

Its test results show approximately:
+17.17 whp / +27.33 ft-lb at 3300 RPM
+23.28 whp / +29.11 ft-lb at 4200 RPM
+25.46 whp / +22.67 ft-lb at 5900 RPM
Peak gain: +15.95 whp / +26.48 ft-lb

Fabspeed also states that the package saves approximately 15 lb compared with the factory components.

Actual performance will vary according to engine specification, vehicle condition, fuel, tune and environmental conditions.

Product Information
Product Information
Fabspeed Valved Center Muffler Bypass X-Pipe (Valved Exhaust Only). Cars with PSE from factory

The Fabspeed Valved Center Muffler Bypass X-Pipe is a performance exhaust upgrade designed for 2012–2016 Porsche 991 Carrera 3.4L and Carrera S 3.8L models equipped with the factory valved exhaust system.

Fits:

  • Porsche 991.1 Carrera C2 3.4L /3.8L 2012-16
  • Porsche 991.1 Carrera C4 3.4L / 3.8L 2012-16  

The system replaces the restrictive factory centre muffler with a freer-flowing X-pipe while retaining the functionality of the Porsche valved exhaust arrangement. This allows the driver to continue benefiting from two distinct exhaust characteristics: a more aggressive sports-car sound with the valves open and a smoother, quieter tone with the valves closed.

Manufactured from 14–16 gauge CNC mandrel-bent T304L stainless steel, the X-pipe is designed to improve exhaust flow, reduce weight and provide long-term resistance to corrosion and high exhaust temperatures.

Fabspeed reports gains of approximately:

  • +16 wheel horsepower
  • +14 lb-ft of torque
  • 12 lb weight reduction compared with the factory centre muffler

Actual performance gains can vary depending on vehicle condition, specification, fuel and environmental conditions.

What This Product Does:
The factory centre muffler helps control exhaust volume but also creates a degree of restriction in the exhaust path.

The Fabspeed X-pipe replaces this muffler with a freer-flowing crossover section, allowing exhaust gases from the two cylinder banks to merge and flow more efficiently toward the rear exhaust outlets.

Its main functions and benefits include:

  • Reducing centre-muffler exhaust restriction
  • Improving exhaust gas flow
  • Increasing exhaust sound and character
  • Retaining factory exhaust-valve operation
  • Supporting improved throttle response
  • Producing measurable horsepower and torque gains
  • Reducing exhaust-system weight
  • Providing a more direct flat-six exhaust note
  • Maintaining compatibility with factory valved side mufflers

Fabspeed also lists the X-pipe as a suitable complement to its Maxflo Performance Side Exhaust System.

Symptoms Of Wear Or Failure:
The factory centre muffler and associated valved-exhaust components are exposed to heat, condensation, vibration and repeated thermal cycling.

Common signs of deterioration can include:

  • Exhaust rattling from the centre muffler
  • Internal muffler components becoming loose
  • Cracked exhaust seams or welds
  • Blowing or hissing noises
  • Black soot around leaking joints
  • Corrosion on pipes or muffler sections
  • Exhaust-valve rattling
  • Valve mechanism sticking open or closed
  • Uneven exhaust sound between operating modes
  • Failure to change exhaust tone when the valve system is activated
  • Loose clamps or mounting hardware
  • Excessive exhaust movement
  • Poor exhaust alignment
  • Unexpected increase in exhaust noise

Some valve-related symptoms may originate from actuators, vacuum lines or electronic controls rather than the exhaust pipework itself, so the complete system should be inspected before replacement.

Why Replacement Matters:
A deteriorated muffler or leaking exhaust connection can allow hot exhaust gases to escape before reaching the intended outlets.

This can lead to:

  • Increased unwanted exhaust noise
  • Rattles and vibration
  • Soot accumulation
  • Excessive heat around surrounding components
  • Deterioration of adjacent exhaust joints
  • Reduced exhaust-system integrity

A malfunctioning exhaust valve can also prevent the system from switching correctly between quieter and louder operating modes.

Replacing damaged components helps restore:

  • Secure exhaust routing
  • Leak-free exhaust connections
  • Correct valve functionality
  • Proper clearance from surrounding components
  • Consistent exhaust operation

Where the original system remains serviceable, the Fabspeed X-pipe is primarily a performance, sound and weight-saving upgrade rather than a necessary repair.
