Manifold / Headers

Evolution header set (Titanium).

Fits:
Porsche 911 (991.2) GT3 RS 2020

Evolution Header Set converts the slip-on system into a full system designed to give noticeably increased power at higher revs. Handcrafted titanium headers incorporate 100 cpsi sports catalytic convertors and side mufflers—all designed to increase power and torque—the Evolution Header Set utilizes integrated catalytic convertors and the functionality of the exhaust valves to deliver an out-and-out attack on the senses. With the valves in the open position, it delivers a sportier and hard-hitting sound, but also has the option of a lower sound level when the valves are closed, perfect for use in more everyday locations. Offering an increased weight savings in the area behind the engine and the rear axle, the reduction will enhance the handling and improve performance.

When installing Akrapovič aftermarket optional link pipes with sports catalytic converters or without catalytic converters, which are developed for use on closed tracks only, remapping the ECU is mandatory. When installing Akrapovič aftermarket exhaust system that was developed for use on closed tracks, we recommend remapping the ECU in order to prevent potential »check engine light« warning signals.

NOTE: Sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001 in the United Kingdom. They are not MOT compliant and must not be used on public roads. These components are intended for race and track use only. If you are located outside the UK, please consult your local laws and regulations to ensure compliance.

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 911 991.2 GT3 and GT3 RS.

Fits:

• Porsche 991.2 GT3 4.0L (500 Bhp) / GT3 RS 4.0L (520 Bhp) 2017-19

Designed for racing, track events and off-road competition use, the system combines high-flow long-tube headers with Burns Stainless merge collectors and integral side muffler bypass pipes equipped with premium Helical exhaust valves.

The system replaces the restrictive factory catalytic-converter-equipped header arrangement and provides a significantly freer-flowing exhaust route from the cylinders into the rear exhaust system.

By improving exhaust gas evacuation and managing exhaust pulses more effectively, the system is designed to improve throttle response, optimise high-RPM breathing and maximise the performance potential of Porsche's naturally aspirated 4.0-litre flat-six engine.

Fabspeed develops its long-tube systems using CAD design and incremental Dynojet testing. The current manufacturer listing does not specify a fixed horsepower or torque increase for this complete system, with both figures currently shown as TBD.

What This Product Does:
The Long Tube Competition Race Header System replaces the factory exhaust manifolds, catalytic converter sections and side-muffler flow path with a high-performance race configuration.

It is designed to:

• Increase exhaust gas flow.
• Reduce exhaust restriction.
• Improve exhaust scavenging.
• Improve throttle response.
• Support stronger torque and power delivery.
• Improve high-RPM engine breathing.
• Reduce restriction from the original catalytic converters.
• Bypass the factory side mufflers when required.
• Retain active exhaust control through Helical valves.
• Produce a much more aggressive motorsport exhaust note.
• Reduce rear exhaust-system mass.
• Support additional competition engine modifications.

Symptoms Of Wear Or Failure:
Competition headers experience extreme thermal and mechanical stress.

Possible symptoms include:

• Ticking noises during cold start.
• Blowing sounds under acceleration.
• Exhaust leaks.
• Soot around header flanges.
• Cracked primary tubes.
• Cracked welds.
• Damaged collectors.
• Loose slip joints.
• Metallic rattling.
• Exhaust vibration.
• Unexpected changes in exhaust sound.
• Reduced engine performance.
• Heat damage around nearby components.

Why Replacement Matters:
Replacing worn or damaged competition headers helps restore:

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

For a track-driven GT3, regular exhaust inspection should form part of preventative maintenance.

Fabspeed Long Tube Race Headers.

The Fabspeed Long Tube Race Headers are a competition-focused exhaust upgrade developed for naturally aspirated Porsche 911 GT3, GT3 RS and 911 R models of the 991 generation.

Fits:

• Porsche 991.1 GT3 3.8L (475 Bhp) 2014-16
• Porsche 991.2 GT3 4.0L (500 Bhp) 2017-19  

Designed for circuit, motorsport and off-road applications, the system replaces the factory catalytic-converter-equipped headers with a carefully developed long-tube header arrangement engineered to improve exhaust scavenging, reduce restriction and maximise the breathing potential of Porsche's high-revving flat-six engine.

Fabspeed developed the system in conjunction with Burns Stainless, using motorsport-derived high-velocity merge collectors and long primary tubes to improve the way exhaust pulses leave each cylinder and combine within the exhaust system.

The headers are manufactured from T321 stainless steel, CNC mandrel bent and hand TIG welded with back-purging. T321 is particularly well suited to high-temperature motorsport exhaust applications because of its excellent resistance to repeated thermal cycling.

Fabspeed's current product listing quotes performance gains of approximately:

+19 HP

+13 lb-ft of torque

These are manufacturer-listed figures from specific testing and should not be regarded as guaranteed gains for every vehicle.

Because the system removes the original catalytic converters, it is specifically intended for closed-course competition and off-road use rather than public-road use.

What This Product Does:
The Long Tube Race Headers replace the original Porsche exhaust manifolds and catalytic-converter assemblies with a freer-flowing competition header system.

They are designed to:

• Improve exhaust gas evacuation from each cylinder.
• Reduce exhaust restriction.
• Improve exhaust pulse scavenging.
• Support increased horsepower and torque.
• Improve throttle response.
• Enhance high-RPM breathing.
• Complement the high-revving character of the GT3 engine.
• Produce a significantly more aggressive exhaust note.
• Reduce catalyst-related exhaust restriction.
• Support additional competition engine and exhaust modifications.

Symptoms Of Wear Or Failure:
Race headers are exposed to severe temperature and vibration.

Possible symptoms of deterioration include:

• Ticking noises from the exhaust.
• Blowing noises during acceleration.
• Visible exhaust leaks.
• Soot around welds or flanges.
• Cracked primary tubes.
• Cracked welds.
• Damaged collectors.
• Loose slip joints.
• Increased exhaust smell.
• Metallic rattling.
• Exhaust vibration.
• Reduced performance.
• Exhaust noise changing unexpectedly.

Why Replacement Matters:
Replacing cracked or damaged headers helps restore:

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

For track-driven cars, header condition should be checked regularly because operating temperatures and mechanical loads can be considerably greater than during normal road driving.

Fabspeed Sport Headers.

The Fabspeed Porsche 991 GT3 Cup Sport Headers are a high-performance replacement for the restrictive factory exhaust headers fitted to Porsche 991 GT3 Cup race cars from 2017 onward.

Fits:

• Porsche 991 GT3 Cup 2017-2019

Designed specifically for competition-focused GT3 Cup applications, these headers improve exhaust gas flow and scavenging, helping the naturally aspirated flat-six engine breathe more efficiently throughout the rev range.

The system features one-piece CNC mandrel-bent primary header tubes, a high-velocity motorsport-style merge collector and specially designed inlet flanges. Fabspeed manufactures the system from a combination of T321 and T304 stainless steel for strength, corrosion resistance and durability under extreme exhaust temperatures.

Integrated German-made HJS 200-cell tri-metallic sport catalytic converters provide substantially increased exhaust flow compared with more restrictive factory catalysts while retaining catalytic treatment.

Fabspeed lists a performance gain of up to approximately 15 HP, although actual output will vary according to vehicle specification, setup and operating conditions. The system also removes approximately 1 kg / 2 lb from the rear of the vehicle compared with the factory arrangement.

What This Product Does:
The exhaust headers collect combustion gases as they leave the engine's individual cylinders and direct them into the remainder of the exhaust system.

On a high-revving GT3 Cup engine, efficient exhaust flow is especially important because the engine must move large volumes of exhaust gas at high RPM.

The Fabspeed Sport Headers are designed to:

• Reduce exhaust restriction.
• Improve exhaust gas velocity.
• Improve cylinder scavenging.
• Reduce pumping losses.
• Support stronger high-RPM performance.
• Improve throttle response.
• Increase potential horsepower.
• Maintain efficient exhaust flow during sustained track use.
• Reduce unnecessary weight at the rear of the vehicle.
• Provide high-flow catalytic treatment through HJS sport catalysts.

Symptoms Of Wear Or Failure:
Competition exhaust systems experience extreme temperatures, vibration and repeated thermal cycling.

Possible symptoms of worn or damaged headers include:

• Ticking or tapping noise from the exhaust area.
• Exhaust note becoming louder than normal.
• Exhaust gases leaking near the cylinder heads.
• Soot marks around header flanges.
• Cracks in the header tubing.
• Cracked welds.
• Distorted mounting flanges.
• Loose mounting hardware.
• Failed exhaust gaskets.
• Rattling from the catalytic converter area.
• Reduced throttle response.
• Loss of high-RPM performance.
• Increased exhaust backpressure.
• Engine-management warning lights.
• Catalyst-efficiency fault codes.
• Unusual exhaust smells.
• Excessive heat around nearby components.

Because GT3 Cup vehicles are subjected to sustained competition use, regular inspection of the exhaust system is particularly important.

Why Replacement / Upgrading Matters:
A GT3 Cup engine depends on efficient airflow at both the intake and exhaust sides of the combustion process.

Restrictive, cracked or damaged headers can reduce the efficiency with which exhaust gases leave the engine.

Replacing worn components or upgrading to a higher-flow header system can help restore or improve:

• Exhaust gas flow.
• Cylinder scavenging.
• Engine responsiveness.
• High-RPM power delivery.
• Exhaust sealing.
• Thermal management.
• Competition reliability.
• Overall exhaust-system efficiency.

For a race car, maintaining predictable performance across repeated high-load sessions is especially important.
