The Fabspeed Porsche 996 GT3 Sport Headers are a high-performance replacement for the factory exhaust headers, designed to improve exhaust flow, optimise exhaust-gas scavenging and enhance the power and sound of the naturally aspirated GT3 flat-six.
Fits:
- Porsche 996 GT3 MKI 1999-02
- Porsche 996 GT3 MKII 2003>>
Hand-crafted from mandrel-bent T304L stainless steel, the headers use one-piece CNC mandrel-bent primary tubes together with F1-style merge collectors to provide a smoother, freer-flowing route for exhaust gases leaving the cylinder heads.
Fabspeed reports improvements of approximately +20 HP and +18 lb-ft of torque, together with an approximate 5 lb weight reduction. The headers also provide a mild increase in exhaust volume while smoothing and enhancing the distinctive flat-six exhaust note.
What This Product Does:
Exhaust headers collect exhaust gases leaving each cylinder and direct them into the remainder of the exhaust system.
Their design has a significant influence on how efficiently the engine can evacuate spent combustion gases.
The Fabspeed Sport Headers are designed to:
- Increase exhaust-gas flow
- Reduce unnecessary exhaust restriction
- Improve exhaust scavenging
- Improve engine breathing
- Increase horsepower and torque potential
- Support performance throughout the RPM range
- Reduce exhaust-system weight
- Produce a mild increase in exhaust volume
- Enhance and smooth the GT3 flat-six exhaust note
Performance Benefits:
Fabspeed lists manufacturer-reported figures of approximately:
Power: +20 HP
Torque: +18 lb-ft
Weight Reduction: Approx. 5 lb
The manufacturer also states that the headers improve power and torque throughout the RPM range.
These figures should not be interpreted as guaranteed results for every vehicle.
Actual performance can vary according to:
- Engine condition
- Existing exhaust configuration
- Catalytic converter configuration
- Rear exhaust system
- Intake modifications
- Engine calibration
- Fuel quality
- Ambient temperature
- Vehicle specification
- Dyno equipment and testing procedure
Why Upgrading Matters:
The original headers do not need to be worn or damaged for these Sport Headers to be installed.
They are primarily a performance upgrade for drivers looking to improve exhaust flow and enhance the GT3's naturally aspirated character.
Reasons for upgrading include:
- Increased exhaust flow
- Optimised exhaust scavenging
- One-piece CNC mandrel-bent primary tubes
- F1-style merge collectors
- T304L stainless-steel construction
- Improved power and torque potential
- Manufacturer-reported +20 HP
- Manufacturer-reported +18 lb-ft
- Approx. 5 lb weight reduction
- Improved performance throughout the RPM range
- Mild increase in exhaust volume
- Enhanced flat-six exhaust note
- Bolt-on installation
- No cutting or welding required
