Catalyst / Bypass

Link pipe set (SS) was tested and developed together with Slip-On Race Line (Titanium) system.

Fits:
Porsche 911 (992) Carrera /S/4/4S/Cabriolet 2019 - 2020 OPF/GPF models

To take the Slip-On Race Line (Titanium) to the next level of its tuning potential, the Link Pipe Set w Cat (SS) is a high-flow set of link pipes with 300 cpsi sport catalytic converters to provide increased performance and add a soundtrack that is truly enthralling. Made from high-quality stainless steel, the addition of these pipes makes remapping the ECU mandatory to get the full potential from the system. With this pairing the sound becomes not just captivating to listen to, but one that gives other senses a thorough workout. The symphonic aural experience gives the engine a broader spectrum of sound, letting the occupants of the car fully enjoy the sporty character of the engine through the exhaust tones.

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 Sport Catalytic Converters With GT2RS Style Outlets + Muffler Adapter.

The Fabspeed Sport Catalytic Converters with GT2RS Style Outlets + Muffler Adapter are a high-performance exhaust upgrade for the Porsche 911 992 Carrera, designed to reduce exhaust restriction, improve turbo response and deliver a significantly more sporting exhaust character.

Fits:

• Porsche 992.1 Carrera 2 3.0L 2021-24
• Porsche 992.1 Carrera 4 3.0L 2021-24
• Porsche 992.1 Carrera 2 Cabriolet 3.0L 2021-24
• Porsche 992.1 Carrera 4 Cabriolet 3.0L 2021-24
• Porsche 992.2 Carrera 2 3.0L 2024>>  

The system replaces the restrictive factory catalytic converters with German HJS 200-CPSI high-flow catalytic converters and incorporates GT2RS-inspired direct exhaust outlets with muffler adapter. This configuration creates a freer-flowing path for exhaust gases after the turbochargers while retaining catalytic exhaust treatment.

Manufactured from CNC mandrel-bent 14–16 gauge T304L stainless steel, the system is engineered as a direct bolt-on installation with no cutting or welding required.

What This Product Does:

• Replaces the factory catalytic-converter assemblies.
• Replaces the restrictive original 800-cell catalysts with HJS 200-CPSI units.
• Reduces exhaust backpressure.
• Allows exhaust gases to leave the turbochargers more efficiently.
• Helps improve turbocharger response.
• Supports increased horsepower and torque.
• Creates a more aggressive sports-car exhaust note.
• Increases audible turbocharger sound.
• Uses GT2RS-inspired direct exhaust outlets.
• Retains catalytic exhaust treatment.
• Reduces exhaust-system weight.
• Provides a modular design that can be converted back to a muffled configuration.
• Retains compatibility with the factory muffler using optional adapter pipes.
• Can also be configured with Fabspeed's Valvetronic exhaust.
• Provides a bolt-on installation without cutting or welding.

Fabspeed's HJS catalysts use a much more open internal structure than the original 800-cell units, helping the turbocharged 992 engine move exhaust gases more efficiently.

Symptoms Of Wear Or Failure:
The Fabspeed system is primarily a performance upgrade, but replacement may also be appropriate when the original catalytic converters have deteriorated.

Possible symptoms of a failing or restricted catalyst include:

• Reduced engine power.
• Sluggish acceleration.
• Increased turbo lag.
• Poor throttle response.
• Engine feeling restricted at higher RPM.
• Difficulty producing normal power under heavy load.
• Check engine warning light.
• Catalyst-efficiency fault codes.
• Rattling or metallic noises from inside a catalytic converter.
• Excessive heat from the catalyst housing.
• Strong or unusual exhaust odours.
• Increased emissions.
• Failed emissions testing.
• Exhaust leaks around joints or flanges.
• Visible damage to the catalyst housing.
• Poor fuel economy.
• Abnormally high exhaust backpressure.

A partially blocked catalyst may be relatively difficult to notice during light driving but become increasingly restrictive as exhaust-gas volume rises under acceleration.

Why Replacement Matters:
Catalytic converters sit directly downstream of the turbochargers and therefore have a significant influence on exhaust flow.

If the internal substrate becomes damaged, contaminated, melted or partially blocked, exhaust gases cannot pass through efficiently.

This increases backpressure and can result in:

• Reduced engine performance.
• Slower turbo response.
• Increased exhaust temperatures.
• Poor high-RPM performance.
• Increased load on the turbocharged exhaust system.
• Engine-management faults.
• Reduced emissions-control effectiveness.

Replacing a damaged or restrictive catalyst restores a clear exhaust path and proper catalytic function.

Catalyst information:
Replacing the restrictive OEM catalyst not only enhances power but also improves sound. By upgrading to our catted downpipes increasing flow while still effectively catalyzing exhaust gases. By allowing for better exhaust gas scavenging and reducing backpressure, these modifications can increase power output, improve turbo spool, and offer a more aggressive exhaust note.
Unlike the ineffective catalytic converters found in generally cheaper aftermarket options ours has been designed for superior performance.

Our high-performance catalytic solution.
Featuring Euro 6 standard purification coatings, our catalytic converters have a higher density of precious metal coatings compared to OEM units on the same surface area. This results in superior exhaust gas conversion performance, allowing for more efficient purification when replacing with a more performance-oriented high-flow Downpipe without releasing harsh, toxic fumes. In terms of design, the catalytic converter employs a three-spiral metal carrier structure that enhances the carrier's shock resistance and durability. This ensures that the catalyst unit remains stable under the continuous impact of pressure waves and pulses from high-horsepower engines.

• Effective operating temperature: 480°F–1470°F
• Short-term tolerance temperature threshold: 1650°F–1830°F
• Long-term tolerance temperature threshold: ≤1560°F Exposure to temperatures above 1470°F for extended periods will shorten the catalyst's lifespan. Main precious metal components and applications: Platinum (Pt) Characteristics: High catalytic activity, heat-resistant, corrosion-resistant. Applications: Oxidizes CO and HC (hydrocarbons). Reduces NOx. Advantages: Stable performance in both oxygen-rich and oxygen-poor environments. Palladium (Pd) Function: HC oxidation: More efficient at oxidizing unburned hydrocarbons (HC) compared to platinum. Advantages: When combined with platinum or other precious metals, it offers better conversion efficiency for unburned hydrocarbons (HC). Rhodium (Rh) Characteristics: Exceptional NOx reduction ability.
