Product Information
Unlock maximum performance for your Porsche 964 Turbo with Fabspeed’s all-in-one Performance Package. This comprehensive upgrade includes a high-flow dual outlet Maxflo muffler, high-performance sport headers with full heat functionality and braided oil lines, and a lightweight, dyno-proven cold air intake system with a BMC air filter - delivering gains in power, sound, and throttle response across the board.  

Fits:
Porsche 964 Turbo (965) 1991-92
Porsche 964 Turbo (965) 1993-94

Kit Contents:

Fabspeed’s high-flow sport headers are designed to retain full cabin heat functionality while unlocking noticeable performance gains. Thanks to a shorter exhaust gas path and smooth mandrel bends, these headers dramatically improve exhaust flow - boosting power, sharpening throttle response, and reducing turbo lag, with boost onset up to 1500 RPM earlier than stock. They also deliver a mild increase in volume, a more pronounced turbo spool sound, and a deeper, more aggressive exhaust tone.

- Constructed from 14-16ga CNC mandrel-bent T304L stainless steel with high velocity F1-style merge collectors for optimum exhaust flow.
- This system will include a drip accumulator with double swivels and Aeroquip lines with adaptors, plus graphite steel layered gasket for a leak proof seal. 
- 7/8"custom braided oil lines with correct 30mm radius Porsche style ball end with OEM fittings will be included to replace the stock oil lines. 
- Retains the stock cabin cockpit heat functionality.
- Simple DIY (Do-It-Yourself) bolt-on installation, no cutting or welding required.
- Backed by Fabspeed's Lifetime Warranty.  


Fabspeed's Maxflo dual outlet muffler delivers a deep, aggressive exhaust note along with a significantly enhanced turbo spool sound—bringing out the true character of your 964 Turbo.  

- Increased horsepower and torque throughout the RPM range. 
- Includes Fabspeed's Deluxe Outlet Tips; polished angle-cut ovals.
- Maxflo Mufflers are radius stress relieved, hydro-formed cases that are pulse TIG welded with 2000 degree ceramic fiber and stainless steel wool packing.
- Constructed from high-quality 14-16 gauge C.N.C. mandrel-bent T304L stainless steel for optimum flow and maximum durability.
- Complete 3.0" tubing for maximum flow.
- Includes 4.5" wastegate tip and all required hardware.
- Simple DIY (Do-It-Yourself) bolt-on installation, no cutting or welding required.

Fabspeed’s high-performance intake system replaces the outdated, heavy steel factory airbox found on 930 and 964 Turbo (965) models - a design originally from the 1970s and '80s that traps heat like a Dutch oven and severely limits airflow. This factory setup bakes the intake air, reducing performance and efficiency. In contrast, Fabspeed’s Cold Air Intake is engineered to reduce weight and deliver significantly cooler, denser air directly to the engine - resulting in dyno-proven horsepower and torque gains.  

- Saves maintenance time, and weighs much less, for better handling and cooler engine temperatures.  
- Increases horsepower and torque by +17.5 HP and +26 ft-lbs. 
- Significant weight savings along with finally an uncluttered CLEAN to BE SEEN awesome engine bay.
- Cleans up engine bay for easier access for maintenance and car shows!  
- Allows fitment of larger intercoolers versus banging into the steel heavy airbox.   
- Supports up to 550+ horsepower.
- VIDEO- installation instructions and photos online. Super simple engineered system.   
- Used and installed by a WHOs WHO of Porsche Turbo engine builders Worldwide!  
- CAD Designed and DYNO developed 100% Guaranteed to be the very best air intake for your 964 Turbo!
- Backed by Fabspeed's Lifetime Warranty.

FITMENT NOTE: After the initial heat cycle, be sure to retighten all exhaust bolts to OEM torque specs to ensure a proper, lasting seal.

NOTE: This system replaces the factory catalytic converter with a high-flow setup and is not MOT compliant, meaning it is intended for race and track use only and must not be used on public roads. If you are located outside the UK, please check your local laws and regulations to ensure compliance before installation.

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.
