- 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.
The manufacturer currently lists:
Horsepower: TBD
Torque: TBD
Weight: TBD
Specific horsepower, torque or weight-saving figures should therefore not be assumed.
Actual performance will depend on factors including:
- Engine condition
- Existing exhaust configuration
- Rear muffler system
- Intake modifications
- ECU calibration
- Fuel quality
- Ambient conditions
- Testing equipment
- Testing methodology
Why Upgrading Matters:
The original catalytic converters do not have to be faulty before fitting the Fabspeed Sport Catalytic Converters.
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
- Enhanced flat-six exhaust note
- Reduced weight compared with factory catalysts
- Retains catalytic converter functionality
- Direct bolt-on installation
- Compatible with factory-style exhaust connections
- Designed specifically for 1997–1999 Porsche 986 models
