High Flow Three Way Catalytic Converter 400 CPSI 123x100mm Universal Euro 5 Exhaust

Meet Euro 5 emission requirements and optimize exhaust flow with the KSRCAT Universal Three-Way Catalytic Converter, engineered for gasoline engines with a durable 400 CPSI metal honeycomb substrate. This unit effectively reduces carbon monoxide, hydrocarbons, and nitrogen oxides while providing a compact metal housing suitable for custom fabrication and direct replacement projects.

Performance Advantages & Usage Notes

• Balanced Backpressure: The 400 CPSI cell density provides efficient catalyst contact area without excessive restriction, helping maintain horsepower in modified or custom exhaust setups.
• Universal Fitment Flexibility: Ideal for workshop modifications where exact OEM dimensions are unavailable; weld-in design allows adaptation to various pipe configurations upon measurement verification.
• System Matching: Achieve best results by pairing with functioning upstream and downstream oxygen sensors and a properly calibrated engine control unit.
