With over 25+ years of Porsche air and water-cooled experience, Fabspeed Motorsport USA offers a great enhancement for your stock exhaust or aftermarket exhaust on your Porsche 992 Twin Turbo / Turbo S. Fabspeed was the first company to design and engineer every Porsche twin-turbo exhaust enhancement. From the 1996 993TT to the 2021 twin-turbo, making a sports car like the 992 Turbo / Turbo S even faster and more exclusive is the domain of Fabspeed. Using only certified high-performance HJS components imported directly from Germany, our system eliminates all risk for black market, grey market, or counterfeit HJS catalytic converters from other companies. Increase the exotic twin-turbocharged Porsche sports car sound and reduce backpressure allowing for a much quicker turbocharger spooling and transient turbo response for the 992 VTG (Variable Turbine Geometry). Fabspeed sport cats replace the restrictive OEM 800 cell catalytic converters with HJS Emissions Technology catalysts guaranteeing NO CEL (Check Engine Light) (on US cars only).
SOUND:
These sport cats give the 992 Turbo a moderate increase in volume. In sport mode pops and gurgles on downshift are tastefully more defined, and overall the exhaust note has a sharper more distinct Porsche flat 6 sound. Turbo spool is also more noticeable compared to the factory system.
POWER
After extensive dyno development, peak power of 585 WHP was obtained at 6600 RPM, compared to the stock peak wheel power of 569 WHP. Max power gains of +54.9 WHP (65.88 crank HP) came at 5500 RPM and +58.9 ft/lbs TQ at 5350 RPM. With faster turbo spooling we saw impressive under the curve gains of +29 whp (34.8 crank hp) at 3000 RPM and +51.4 ft/lbs TQ. See our dyno graph above for more details.

Why We Choose HJS Catalytic Converters:
HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.

- Porsche Boxster 986 2.5L 1997-99
The Fabspeed Porsche 986 Boxster Sport Headers are a performance exhaust upgrade designed to improve exhaust flow, scavenging, throttle response and flat-six sound on Porsche 986 Boxster.
Fits:
- Porsche Boxster 986 2.5L 1997-99
The headers use equal-length CNC mandrel-bent primary tubes combined with F1-style high-velocity merge collectors. This configuration is designed to improve the way exhaust gases leave each cylinder and merge into the exhaust system, reducing unnecessary restriction and supporting more efficient engine breathing.
1997–1999 Porsche 986 Boxster / Boxster S: The factory headers do not incorporate primary catalytic converters, so the Fabspeed headers for these vehicles are supplied without sport catalysts.
Fabspeed reports +8 wheel horsepower and +4 lb-ft of torque when the Sport Headers are installed with the Fabspeed Maxflo Performance Exhaust System. These are manufacturer-reported figures from a specific vehicle and are not guaranteed results for every application.
What This Product Does:
Exhaust headers collect combustion gases as they leave the engine's cylinder heads and direct them into the remainder of the exhaust system.
The design and length of the individual primary tubes influence how efficiently these exhaust pulses leave the cylinders.
The Fabspeed Sport Headers are designed to improve this process through equal-length primary tubing and high-velocity merge collectors.
Potential benefits include:
- Improved exhaust flow
- Improved exhaust scavenging
- Reduced exhaust restriction
- Improved cylinder evacuation
- Sharper throttle response
- Increased horsepower and torque potential
- Stronger high-RPM performance
- Enhanced naturally aspirated flat-six sound
1997-1999 Header Configuration:
- On 1997–1999 Porsche 986 Boxster and Boxster S models, the factory headers do not contain primary catalytic converters.
- Fabspeed therefore supplies these model-year applications without catalytic converters incorporated into the Sport Headers.
- This is an important distinction when ordering because the header configuration differs from later 986 models.
Why Upgrading Matters:
The original Porsche headers do not need to have failed before fitting the Fabspeed Sport Headers.
This product is primarily a performance and sound upgrade.
Reasons for upgrading include:
- Equal-length primary tubes
- CNC mandrel-bent construction
- F1-style high-velocity merge collectors
- Improved exhaust scavenging
- Improved exhaust flow
- Reduced exhaust restriction
- Increased performance potential
- Sharper throttle response
- Enhanced flat-six exhaust sound
- Bolt-on installation
- Designed specifically for Porsche 986 Boxster and Boxster S models

- Porsche Boxster 986 2.5L 1997-99
The Fabspeed Porsche 986 Boxster Primary Sport Catalytic Converters are high-flow replacement catalysts designed for 1997–1999 Porsche 986 Boxster and Boxster S models.
Fits:
- Porsche Boxster 986 2.5L 1997-99
Designed to replace the more restrictive factory catalytic converters, these performance catalysts improve exhaust-gas flow while retaining catalytic converter functionality. The result is a more performance-oriented exhaust path designed to improve throttle response, support increased power potential and enhance the naturally aspirated Porsche flat-six exhaust note.
Fabspeed uses HJS/EMITEC high-flow catalytic converter technology, with the manufacturer specifying a 200 CPSI (cells per square inch) catalyst design. Fabspeed states that these catalysts can flow approximately 90–93% of the volume of a straight pipe in many applications while continuing to provide exhaust-gas treatment.
The converters are designed as a direct bolt-on replacement for the original catalytic converters, making them suitable for use with the factory OEM-style muffler or aftermarket exhaust systems designed to accept the original Porsche catalytic converter arrangement.
What This Product Does:
Catalytic converters form part of the vehicle's exhaust system and are designed to chemically convert harmful exhaust pollutants into less harmful compounds before gases leave the tailpipe.
However, exhaust gases must pass through a catalyst substrate, which creates some resistance to flow.
The Fabspeed Primary Sport Catalytic Converters use a high-flow catalyst design intended to reduce this restriction compared with the original factory catalysts.
Potential benefits include:
- Improved exhaust flow
- Reduced exhaust restriction
- Improved throttle response
- Increased performance potential
- Reduced weight compared with the original catalysts
- Enhanced flat-six exhaust sound
- Retained catalytic converter functionality
200CPSI High-Flow Catalyst Design:
- Catalytic converter density is commonly described in cells per square inch (CPSI).
- A performance-oriented 200 CPSI catalyst provides a relatively open exhaust path while maintaining the large internal surface area required for catalytic exhaust-gas treatment.
- Fabspeed states that its HJS/EMITEC 200 CPSI catalysts can flow approximately 90–93% of a straight pipe in many applications.
- This high-flow construction is designed to provide a balance between exhaust performance and catalyst functionality.
Performance:
Fabspeed states that these Sport Catalytic Converters improve power and throttle response, but the current product listing does not publish specific numerical gains.

They can also be installed as a performance upgrade.
Reasons for upgrading include:
- High-flow 200 CPSI catalyst design
- HJS/EMITEC catalyst technology
- Reduced exhaust restriction
- Improved exhaust flow
- Improved throttle response
- Increased performance potential
