Fabspeed Maxflo Performance Exhaust System. Porsche 996 GT3 (1999-2005)  ❭  FSPOR996GT3MAX

The Fabspeed Porsche 996 GT3 Maxflo Performance Exhaust System is a high-performance muffler upgrade designed to improve exhaust flow, reduce weight and give the naturally aspirated GT3 flat-six a deeper, more aggressive exhaust note.

Fits:

• Porsche 996 GT3 MKI 1999-02
• Porsche 996 GT3 MKII 2003>>  

Replacing the restrictive factory mufflers with freer-flowing performance components allows exhaust gases to leave the engine more efficiently while retaining compatibility with the original Porsche exhaust tips.

Manufactured from 14–16 gauge CNC mandrel-bent T304L stainless steel, the Maxflo system combines performance-oriented exhaust flow with excellent resistance to heat, corrosion and repeated thermal cycling.

Fabspeed reports gains of approximately 8 wheel horsepower and 10 ft-lb of torque, together with a 12 lb reduction in weight compared with the factory components.

What This Product Does:
The Maxflo Performance Exhaust replaces the original rear mufflers.

The mufflers form an important part of the exhaust system, controlling exhaust noise while providing a route for gases leaving the engine.

A performance muffler system reduces unnecessary restriction while maintaining sufficient sound control for its intended application.

The Fabspeed Maxflo system is designed to:

• Improve exhaust-gas flow
• Reduce exhaust restriction
• Increase horsepower and torque potential
• Reduce rear vehicle weight
• Produce a deeper performance exhaust note
• Increase exhaust volume compared with the factory mufflers
• Maintain compatibility with OEM exhaust tips
• Provide a durable stainless-steel replacement for ageing factory mufflers

Improved Exhaust Flow:
The naturally aspirated Porsche 996 GT3 engine depends on efficient intake and exhaust flow to produce power throughout the rev range.

Excessive exhaust restriction makes it more difficult for gases to leave the engine efficiently.

The Maxflo system uses freer-flowing mufflers and mandrel-bent tubing to provide a smoother exhaust path.

Potential benefits include:

• Improved exhaust evacuation
• Reduced restriction
• Improved engine breathing
• Sharper throttle response
• Improved power delivery
• Increased performance potential throughout the RPM range

Manufacture Reported Performance:
Fabspeed reports dyno-tested gains of approximately:

Power: +8 WHP
Torque: +10 ft-lb
Weight Reduction: Approx. 12 lb

These figures are manufacturer-reported results obtained from a specific test vehicle and should not be considered guaranteed gains for every 996 GT3.

Actual results can vary according to:

• Engine condition
• Existing exhaust configuration
• Intake modifications
• Engine calibration
• Fuel quality
• Ambient temperature
• Vehicle specification
• Testing equipment and methodology

More Aggressive GT3 Exhaust Sound:
One of the principal benefits of the Maxflo system is its enhanced exhaust character.

The factory GT3 exhaust provides a relatively controlled sound for road use. The Fabspeed system allows more of the naturally aspirated flat-six character to be heard.

The result is designed to provide:

• Deeper exhaust tone
• More aggressive sound under acceleration
• Stronger flat-six character
• Increased presence throughout the RPM range
• More exotic performance-car sound

Fabspeed specifically designs the system to provide this more aggressive character while keeping cabin drone to a minimum.

Final exhaust volume and tone will depend on the other exhaust components fitted to the vehicle.

Why Upgrading Matters:
The factory exhaust does not need to have failed for the Maxflo system to be installed.

This is primarily a performance upgrade designed for owners who want increased exhaust character, improved flow and reduced weight.

Reasons for upgrading include:

• Improved exhaust flow
• Reduced restriction
• Manufacturer-reported +8 WHP
• Manufacturer-reported +10 ft-lb
• Approx. 12 lb weight reduction
• More aggressive GT3 exhaust sound
• Minimal cabin drone by performance-exhaust standards
• T304L stainless-steel construction
• CNC mandrel-bent tubing
• Compatibility with factory exhaust tips
• Bolt-on installation
• No cutting or welding required
