Description
Enhance performance and sound while maintaining refined engineering with Capristo’s 250 Cell High-Flow Sport Cats—crafted specifically for Porsche 991 Turbo models.
These Capristo 250 Cell Sport Catalytic Converters (Part #: 02PO03903038) are designed for the following models and are compatible with either the OEM muffler or Capristo ECE Valved Exhaust System:
- Porsche 991.1 Turbo / Turbo S (2013–2016)
- Porsche 991.2 Turbo / Turbo S (2016–2019)
Key Features:
- Constructed from T309 (1.4828) stainless steel, hand-polished to a mirror finish
- Utilizes 250 cell per square inch metallic substrate for optimal gas flow and emissions balance
- 5.2-inch diameter housings prevent flow restriction and support the full efficiency of valved exhaust setups
- Designed to maximize exhaust velocity without compromising torque or drivability
- Compatible with both Capristo and OEM muffler systems for flexible installation
- Improves turbo spool response and engine breathing across the powerband
- Bolt-on installation to existing OEM mounting points
Why 250 Cell Sport Cats?
The substrate’s 250 cell/in² configuration allows for larger internal flow channels compared to OEM, resulting in:
- Reduced backpressure
- Faster turbo response
- Increased horsepower potential
- Enhanced sound without drone
Capristo’s 5.2” package design ensures the substrate is not compressed, which means optimal exhaust flow is preserved—critical for high-output turbocharged engines like the 991 Turbo.
Backpressure Optimization:
When paired with Capristo’s valved exhaust system, the sport cats:
- Help maintain backpressure at low RPM to support torque and catalytic efficiency
- Fully utilize high-flow capability at wide-open throttle for performance at high RPMs
This dual-mode behavior ensures the best balance between daily drivability and track performance.
Installation:
- Direct-fit upgrade using OEM mounting points
- No cutting or welding required
- Compatible with OEM muffler or Capristo ECE exhaust system
IMPORTANT NOTES:
- Recommended for Off-Road and Track Use Only
- Replacing OEM catalytic converters may trigger a Check Engine Light (CEL)
- ECU tuning or O2 sensor extensions are recommended to prevent CEL recurrence
