Ceramic Three Way Catalytic Converter 123x55mm 600CPSI Universal

Routine exhaust degradation and failed emissions inspections don’t require expensive custom-fabricated parts. This KSRCAT ceramic three-way catalytic converter delivers reliable pollutant reduction through a densely packed 600 cells-per-square-inch honeycomb core split by precision internal walls. Designed as a direct cross-reference replacement, it efficiently neutralizes carbon monoxide, unburned hydrocarbons, and nitrogen oxides while maintaining smooth exhaust gas velocity. The heat-stabilized ceramic body resists thermal shock and cracking, ensuring longevity even under heavy traffic stops-and-go cycles or sustained highway cruising.

Fabricated to a standard outer dimension of 123 millimeters wide by 55 millimeters long, the round universal profile drops into most OBD-compliant exhaust routing without altering suspension clearance or requiring custom hangers. You get factory-level emission control with a straightforward bolt-and-weld swap that restores check-engine codes related to catalyst efficiency and brings your vehicle back into regulatory compliance.

Benefits & Tips

• Efficiency recovery: Replaces depleted catalyst cores to eliminate P0420/P0430 codes and restore proper air-to-fuel feedback signals.
• Optimal flow balance: The 600 CPSI structure filters toxins without creating restrictive backpressure, preserving throttle response and fuel economy.
• Fitment preparation: Clean cut edges thoroughly and tack-weld both sides evenly before completing seam passes to prevent heat-induced warping during initial startup.

Warnings & Reminders

This converter is engineered specifically for original-equipment exhaust configurations. It is not rated for modified piping, turbocharged systems with altered manifold plumbing, or competition vehicles operating without oxygen sensors. Improper cutting angles, misaligned joints, or insufficient weld penetration can lead to exhaust leaks, sensor false readings, or premature core failure. Follow standard fabrication procedures and verify chassis ground clearance before final installation.
