Description
Take your 991.2 GT3 or GT3 RS to the next level of performance and sound with Capristo’s high-performance headers with integrated 250 Cell Sport Cats. Designed to offer the perfect blend of increased power, superior exhaust flow, and the legendary Capristo exhaust tone, these headers deliver serious performance gains while maintaining daily drivability.
The Capristo Performance Header System with Integrated 250 Cell Sport Cats (Part #: 02PO08603018) is engineered for:
- Porsche 991.2 GT3 (2017–2019)
- Porsche 991.2 GT3 RS (2018–2019)
Note: The Capristo underbody engine cover only fits the 991.2 GT3 RS. For the 991.2 GT3, the OEM underbody protection must be modified to accommodate this header system.
Key Features:
- Bespoke manifold routing optimized for flow and performance
- Integrated 250-cell per square inch catalytic converters
- Constructed from T309 (1.4828) stainless steel – highly durable, lightweight, and polished to a mirror finish
- Manufactured using advanced 3D laser scanning, CAD design, CNC-bending, and milling in Germany
- Bolt-on fitment to OEM mounting points – no permanent modifications required
- Optimized for use with OEM or Capristo valved exhaust systems
- Provides substantial weight savings over OEM manifolds
Why 250 Cell Sports Cats?
The 250 CPSI metallic substrate in the integrated catalytic converters delivers:
- Higher exhaust flow rates vs. OEM
- Lower backpressure to improve throttle response and top-end power
- Maintains a balance between emissions compliance and performance gains
- Housed in a 5.2-inch body to avoid bottlenecks and preserve flow dynamics
This layout ensures the exhaust system performs equally well under street or track conditions.
Performance Benefits:
- Faster exhaust scavenging = improved torque and HP
- Sharper throttle response
- Enhanced engine tone, with rich, motorsport-inspired acoustics
- Optimized thermal properties for longevity and consistent performance
Installation:
- Direct fit to factory mounting points
- No cutting or welding required
- Compatible with both OEM and Capristo exhaust components
- For 991.2 GT3, minor modification of OEM underbody protection is required.
- For 991.2 GT3 RS, Capristo underbody cover is included and compatible.
IMPORTANT NOTES:
- Recommended for Off-Road and Track Use Only
- Replacing OEM catalytic converters may trigger a CEL (Check Engine Light)
- To prevent CELs, ECU tuning or O2 sensor extensions are recommended
