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.
- Backed by Fabspeed's Lifetime Warranty.  

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 Catalyst / Bypass

Title: Porsche Exhaust Catalyst and Bypass Sports Catalyst: Technical Specifications and Benefits

Key Points:

Enhanced Performance: Upgrading your Porsche's exhaust catalyst or opting for a bypass sports catalyst can significantly improve performance by increasing horsepower and torque output. These aftermarket options are designed to optimize exhaust flow, resulting in improved engine efficiency and throttle response.

Enhanced Sound: An original Porsche or aftermarket exhaust catalyst can enhance the auditory experience of your vehicle. They offer a deeper, more aggressive exhaust note, providing a sportier sound that complements the performance-oriented nature of a Porsche.

Compliance with Emissions Standards: When purchasing an exhaust catalyst, it is crucial to consider its compliance with local emissions regulations. Porsche exhaust catalysts are engineered to meet strict emissions standards, ensuring that your vehicle remains environmentally friendly while delivering enhanced performance.

Quality and Durability: Original Porsche exhaust catalysts are manufactured to the highest standards, ensuring exceptional quality and durability. Aftermarket options from reputable brands also offer similar reliability, providing a long-lasting solution for your Porsche's exhaust system.

Easy Installation: Both original Porsche and aftermarket exhaust catalysts are designed to be direct replacements, making installation relatively straightforward. However, it is essential to follow the manufacturer's instructions or seek professional assistance to ensure proper fitment and optimal performance.
