Description
Maximize flow and performance with this premium pair of Capristo 250 Cell Sport Cats, designed to bolt directly to the OEM or Capristo exhaust system.
These Capristo 250 Cell Sport Catalytic Converters (Part #: 02PO03903034) fit the following vehicles and are designed for use with either the OEM muffler or a Capristo ECE Valved Exhaust System:
- Porsche 991.2 Carrera GTS (2017–2019)
- Porsche 991.2 Carrera S or other models equipped with GTS-style mufflers
Product Highlights:
- Manufactured from T309 (1.4828) stainless steel – selected for its superior heat tolerance, acoustic resonance, and resistance to corrosion
- Hand-polished to a mirror finish for a premium look and enhanced durability
- Compatible with Capristo ECE mufflers or factory OEM mufflers – direct bolt-on installation
- Uses high-flow 250 cell per square inch substrates for optimized gas flow
- Packaged in 5.2-inch housings to preserve flow efficiency without restriction
- Enhances engine responsiveness, especially at higher RPMs
- Maintains low-end torque and catalytic performance via proper backpressure balance
By utilizing a larger housing and lower cell density, these Sport Cats flow significantly more exhaust gas than stock, improving performance while still supporting catalytic function. The design helps optimize power at high RPMs without sacrificing low-end driveability.
Technical Insight:
- Cell count determines how much exhaust can pass through. Lower cell counts = higher flow.
- Capristo's 250-cell design is a perfect balance for street performance and track functionality.
- The 5.2” canister diameter ensures the substrate is not choked, enabling full use of the valved system’s tuning.
Installation Details:
- Direct bolt-on using existing OEM mounting points
- No cutting, welding, or modification required
- Can be installed with either Capristo or OEM mufflers
IMPORTANT USAGE NOTES:
- Recommended for Off-Road and Track Use Only
- Replacing your OEM catalytic converters may trigger a Check Engine Light (CEL)
- To resolve CELs, ECU tuning or use of O2 sensor spacers/extensions is recommended
