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.
- 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Fabspeed’s high-performance intake system replaces the outdated, heavy steel factory airbox found on 930 and 964 Turbo (965) models - a design originally from the 1970s and '80s that traps heat like a Dutch oven and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.
