Product Information

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.

It's a challenge to develop an aftermarket exhaust for the great 911. The Akrapovič engineers have prepared a superb system with a dual nature. By using the optional Akrapovic sound kit, the driver can fully control the exhaust valves, which are controlled by the car's electronics if no optional part is used. When the valves are closed, the 911 sounds deeper than stock, but not louder. When the valves are open, expect a completely opposite, pure racing sound, with adrenaline-pumping bangs. Keeping the drone effect away was one of the main tasks. The Slip-On is made of special heat-resistant durable titanium alloy, with computer-designed premufflers, main mufflers, and pipes to deliver more power, more torque, weight reduction, and improved throttle reponse.

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.
  • Ideal for performance upgrades or restorations.
