Fabspeed Long Tube Competition Race Header System. 

The Fabspeed Long Tube Competition Race Header System is a complete motorsport-focused exhaust upgrade developed for the Porsche 911 997 GT3 and GT3 RS from 2006–2009.

Fits:

• Porsche 997 MK1 GT3 / GT3 RS 2007-09  

Designed specifically for racing, track events and closed-course competition use, the system combines long-tube performance headers with Burns Stainless high-velocity merge collectors and integral side muffler bypass pipes incorporating Helical exhaust valves.

The system replaces the restrictive factory catalytic-converter-equipped header arrangement, allowing exhaust gases to travel from the cylinder heads through a significantly freer-flowing exhaust path.

By improving exhaust-gas evacuation and exhaust-pulse scavenging, the system is designed to improve throttle response, support stronger power delivery across the rev range and enhance the high-RPM character of the naturally aspirated GT3 engine.

Fabspeed developed the system through CAD design, Dynojet testing and track development, working in conjunction with Burns Stainless on the collector design.

Fabspeed currently lists:

+30 HP

Approximately 40 lb / 18.1 kg weight reduction from the rear of the vehicle

Torque gain currently listed as TBD

Actual performance will vary according to vehicle condition, engine specification, fuel, calibration, environmental conditions and accompanying modifications.

What This Product Does:
The Fabspeed Long Tube Competition Race Header System replaces the original header and catalytic-converter arrangement with a freer-flowing competition exhaust configuration.

It is designed to:

• Increase exhaust gas flow.
• Reduce exhaust restriction.
• Improve cylinder scavenging.
• Improve throttle response.
• Support increased horsepower.
• Improve high-RPM engine breathing.
• Reduce weight from the rear of the vehicle.
• Remove restriction associated with the factory catalytic converters.
• Incorporate side muffler bypass pipes.
• Retain controllable exhaust routing through Helical valves.
• Produce a substantially more aggressive GT3 exhaust note.
• Support additional competition engine modifications.

Symptoms Of Wear Or Failure:
Possible signs of header deterioration include:

• Ticking during cold start.
• Blowing noises under acceleration.
• Exhaust leaks.
• Black soot around flanges.
• Cracked primary tubes.
• Cracked welds.
• Loose collector joints.
• Damaged collectors.
• Metallic rattling.
• Increased exhaust vibration.
• Unexpected changes in exhaust sound.
• Loss of performance.
• Heat damage around surrounding components.

Why Replacement Matters:
Replacing cracked, leaking or damaged competition headers helps restore:

• Correct exhaust sealing.
• Intended exhaust scavenging.
• Smooth gas flow.
• Proper collector operation.
• Correct valve function.
• Safe containment of extremely hot exhaust gases.
• Structural integrity.
• Consistent performance.

For vehicles used regularly on circuit, exhaust-system inspection should form part of routine maintenance.

Fabspeed Sport Headers.

The Fabspeed Porsche 911 GT3 Cup Sport Headers are a high-performance replacement for the restrictive factory exhaust headers fitted to 997 and 991.1-generation Porsche 911 GT3 Cup race cars from 2007–2016.

Fits:

• Porsche 997 MK1 GT3 CUP 2007-09
• Porsche 911 (997) GT3 CUP 2010
• Porsche 991 GT3 Cup 2016

Designed specifically for competition-focused GT3 Cup applications, the system improves exhaust gas flow and scavenging to help the naturally aspirated flat-six engine breathe more efficiently throughout the rev range. The result is improved throttle response and the potential for increased power and torque.

Each header assembly incorporates German-made 200-cell HJS tri-metallic high-flow sport catalytic converters. These performance catalysts are designed to offer substantially less exhaust restriction than conventional catalysts while retaining catalytic treatment of the exhaust gases.

The headers are manufactured from high-quality 14–16 gauge stainless steel using CNC mandrel-bent tubing and feature high-velocity 3-into-1 pyramidal investment-cast merge collectors. This collector design is intended to improve exhaust scavenging as the individual cylinder exhaust pulses combine.

Fabspeed lists gains of up to 22 HP and 37 units of torque for this product, although actual results depend on the vehicle, engine specification, environmental conditions and accompanying modifications. The manufacturer also lists a reduction in weight compared with the factory arrangement.

What This Product Does:
The exhaust headers collect exhaust gases leaving each cylinder and direct them towards the remainder of the exhaust system.

On a high-revving naturally aspirated race engine such as the GT3 Cup flat-six, header design has a significant effect on the speed and efficiency with which exhaust gases leave the combustion chambers.

The Fabspeed Sport Headers are designed to:

• Reduce restriction compared with the factory header arrangement.
• Improve exhaust gas velocity.
• Promote more effective cylinder scavenging.
• Reduce exhaust backpressure.
• Allow the engine to expel combustion gases more efficiently.
• Improve throttle response.
• Support increased horsepower and torque.
• Maintain high exhaust flow at elevated engine speeds.
• Improve performance across the usable RPM range.
• Provide high-flow catalytic conversion through the HJS sport catalysts.

Symptoms Of Wear Or Failure:
Exhaust headers operate in an extremely demanding environment and are exposed to intense heat, vibration and repeated thermal cycling.

Possible symptoms of deteriorated factory or aftermarket headers include:

• Ticking or tapping noises from the exhaust area.
• Exhaust noise becoming louder than normal.
• Exhaust gases escaping around the cylinder-head flange.
• Soot deposits around header joints or welds.
• Cracks in the header tubing.
• Cracked or damaged welds.
• Distorted exhaust flanges.
• Loose header fasteners.
• Damaged exhaust gaskets.
• Rattling noises from the catalytic converters.
• Metallic noises from loose catalyst material.
• Reduced engine performance.
• Slower throttle response.
• Increased exhaust backpressure.
• Engine-management warning lights.
• Catalyst-efficiency fault codes.
• Unusual exhaust smells.
• Excessive heat around surrounding components.

Race cars should be inspected regularly because repeated high-temperature track operation can accelerate fatigue of exhaust components.

Why Replacement / Upgrading Matters:
Efficient exhaust flow is essential to extracting maximum performance from a GT3 Cup engine.

A restrictive, damaged or leaking exhaust header can interfere with exhaust scavenging and reduce engine efficiency.

Replacing worn factory components or upgrading to the Fabspeed Sport Headers can help restore or improve:

• Exhaust gas flow.
• Cylinder scavenging.
• Throttle response.
• High-RPM performance.
• Engine breathing.
• Power and torque potential.
• Exhaust-system sealing.
• Competition reliability.

For a race vehicle, consistent performance is as important as peak output. Exhaust leaks or deteriorating components can become progressively worse under sustained track temperatures.
