Fabspeed Valvetronic Nordschleife cat-back exhaust system.

fabspeed

The Fabspeed Valvetronic Nordschleife Cat-Back Exhaust System gives the 992 GT3 a truly exotic sports car sound, all while retaining the functionality of PSE (Porsche Sport Exhaust). Our design process started with 3D scanning the entire OEM exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and dyno testing we decided to use our signature cast X-Pipe to tie the two cylinder banks together for exhaust scavenging and to defeat resonance. The exhaust valves are made by Helical Limited in the United Kingdom. These ISO 9001 certified valves are the same ones Ferrari, McLaren and Porsche use on their GT cars. The piping is mandrel bent from T304 Stainless steel, and you have five different tip options to choose from.

SOUND:

With PSE off our Valvetronic exhaust gives a nice subtle increase in volume. With PSE on it turns the 4.0L's exhaust note into a truly exotic sound with a significant increase in volume. The exhaust note changes from the smooth purr of the OEM exhaust to the aggressive race-bred snarl of a 911 CUP car. (If you need to cut down on how loud your exhaust is because of race track rules, we sell turn down tips which cut 3-6db of exhaust SPL.)

POWER:

This system improves on Porsche's design by increasing pipe diameter from 2.5 in to 2.75 in and using our signature cast X-pipe instead of the factory H-Pipe. On our DynoJet we saw +14 whp at 4200 RPM and a healthy dose of torque down low at 4200 RPM gaining 17 ft/lbs of tq. That's 16 HP gain at the crank.

FEATURES:

Fits all Porsche 992 GT3 / GT3 RS 2022+ Models worldwide w/o monitored GPF (Solution for GPF monitored cars will be released shortly)
• Significant Dyno gains across the RPM band. +17 ft/lbs tq @ 4200RPM and +14 whp @ 4200RPM
• Weight savings of 5lbs / 2.3KGs vs the factory exhaust
• Completely retains PSE valved exhaust functionality
• Uses aerospace quality Helical Limited exhaust valves imported from the U.K.
• Incorporates our signature cast X-pipe for superior flow and exhaust scavenging
• This cat-back system is emissions legal in all 50 states and the rest of the world (ROW)
• Constructed from high-quality 14-16ga CNC mandrel-bent T304L stainless steel for optimum flow and maximum durability
• Laser scanned and CAD designed for perfect OEM fitment using an Ametek Handyscan 700
• No Check Engine Light guaranteed
• Simple DIY bolt-on installation, no cutting or welding required
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

Fits
Porsche 992 GT3

RACETRACK USE ONLY
These components are designed and developed for racetrack use and to maximise the car's performance. They are not street legal and must be installed by professionals in the sector.

The kit includes
• Long Pipe Headers
• Rear Muffler
• Secondary Lambda Harnesses and ECU flasher with the specific Tubi Style map.

Installation of this components requires specific instructions not provided in the workshop manual. The instructions are provided in the package or can be downloaded from www.tubistyle.it

ECU REMAPPING FOR PERFORMANCE
On turbo cars, catalytic converter replacement may modify turbocharger operating conditions and cause a deterioration of the torque delivery curve. To ensure full benefit from the new racing component, the engine's ECU must be reprogrammed to maximise performance. If the engine warning light comes on, the ECU must always be reprogrammed to eliminate it.

ECU REMAPPING OPTIONS - STAGE 1 FLASHER
Tubi Style Flasher is a user-friendly tool that permits both to the workshop and to the car owner to remap the ECU trough the OBD car port. This flasher permits to apply to the ECU a software change that upgrades engine power and torque, turns OFF the CEL light and maintains always open the exhaust valve when a sport driving mode is selected.

SOUND - STRAIGHT PIPE
The straight pipe version guarantees a direct path from the engine, removing all factors which may affect the acoustic tuning.

END TIPS NUMBER AND POSITION - 1 + 1 CENTRAL
The end tips emerge separately from the centre of the bumper.

MATERIAL - INCONEL 625
The component material required to withstand high temperatures. At the technical state of the art, it is used in F1 cars and in the aviation industry. Its excellent mechanical and thermal stress resistance enable the use of thinner sheet metal, reducing component weight.

MAIN PIPE DIMENSION - 65mm
This is the diameter in mm of the main pipe of the exhaust system.

CATALYTIC CONVERTER REMOVAL - 300 CELLS
Race catalytic converters have fewer cells than standard factory systems. This reduces exhaust back pressure while still cutting pollutant emissions and boosts power and sound.

EXHAUST VALVE - ELECTRIC
The exhaust system is complete with electric valve. The electric actuator is not included and the standard actuator already installed on the car must be used. Control of the original valve is still provided.

HEAT SHIELDING - INSULATED
Tubi Style ensures maximum protection for components in critical and dangerous positions by using insulation made with the same technology employed by car manufacturers.

GASOLINE PARTICULATE FILTER - REMOVED
To reduce back pressure on the exhaust and increase noise output, this component removes the standard GPF.

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.

About All Silencers / Mufflers

Standard Exhaust Systems – Engineered for Performance, Sound & Longevity

A standard exhaust system is essential for your Porsche’s performance, efficiency, and sound. It controls the flow of exhaust gases from the engine, reduces emissions, manages noise levels, and ensures balanced back pressure for optimal power delivery.

At Design911, we supply standard exhaust systems built from high-grade stainless steel and corrosion-resistant materials. Designed to meet or exceed manufacturer performance standards, these systems deliver the perfect blend of durability, refinement, and performance — ideal for both daily driving and restoration projects.

Each exhaust system is developed to ensure precise fitment, excellent gas flow, and an authentic Porsche exhaust note that retains the car’s original character.

What Do Standard Exhaust Systems Do?

A standard exhaust system performs several vital roles that keep your Porsche running efficiently, cleanly, and safely.
