Developed with track use in mind, the Supercup system replaces the more restrictive factory rear exhaust arrangement with freer-flowing 2.25-inch CNC mandrel-bent T304L stainless-steel tubing. The straight-through configuration dramatically reduces restriction while allowing the distinctive GT3 flat-six exhaust note to become considerably more pronounced.

Fabspeed reports gains of approximately +20 HP and +17 lb-ft of torque, together with an approximate 10 lb reduction in weight. Actual results will depend on the individual vehicle, exhaust configuration and operating conditions.

What This Product Does:
The exhaust system carries combustion gases away from the engine while influencing exhaust restriction, engine breathing, sound and overall performance.

The factory system must balance performance with road-car requirements for noise, refinement and comfort.

The Fabspeed Supercup system takes a much more performance-focused approach.

Its straight-through design is intended to:

• Dramatically reduce exhaust backpressure
• Improve exhaust-gas flow
• Improve engine breathing
• Increase horsepower and torque potential
• Reduce exhaust-system weight
• Produce a significantly louder exhaust note
• Emphasise the naturally aspirated flat-six sound
• Provide a more motorsport-oriented driving experience

• The defining feature of this system is its straight-through exhaust configuration.
• Rather than prioritising maximum sound suppression, the Supercup system provides a freer route for exhaust gases leaving the engine.
• Reduced restriction can help exhaust gases leave the engine more efficiently, particularly at higher engine speeds where gas volume increases substantially.
• This makes the system particularly appropriate for performance and track-focused 996 GT3 applications.

Power: +20 HP
Torque: +17 lb-ft
Weight Reduction: Approx. 10 lb

These figures are manufacturer-reported and should not be considered guaranteed gains for every vehicle.

Actual performance can vary according to:

• Engine condition
• Existing exhaust configuration
• Catalytic converter configuration
• Intake modifications
• Engine calibration
• Fuel quality
• Ambient conditions
• Vehicle specification
• Testing equipment and procedure

The Supercup is primarily a performance and motorsport-style upgrade.

Reasons for upgrading include:

• Dramatically reduced exhaust backpressure
