High Activity Catalytic Converter Substrate 100x100mm Stainless Steel With 200 Or 300 Cell Density

Restore compliance and optimize exhaust flow with this high-activity catalytic substrate engineered for gasoline passenger cars and light commercial vehicles. Measuring exactly 100 × 100mm, this stainless steel honeycomb core meets E5 European emission standards while offering precise dimensional control for direct replacement. The integral forming construction prevents cracking under vibration, and the precious metal coating ensures effective conversion of CO, HC, and NOx into harmless gases.

The metallic base provides superior thermal conductivity compared to ceramic carriers, achieving fast light-off speeds to minimize cold-start emissions. Its high-temperature resistance and anti-peeling coating maintain stability during rigorous operation, solving issues related to inefficient purification during startup and extended high-load driving. Whether servicing annual emission inspections or performing exhaust refits, this substrate offers a reliable upgrade over traditional materials.

Performance Selection & Installation Advice

Choose the cell density based on your vehicle's configuration and goals:

• 200 CPSI Version: Features larger pore channels to deliver ultra-low backpressure, making it the optimal choice for modified vehicles where maximizing horsepower and exhaust flow is the priority.
• 300 CPSI Version: Provides a higher channel count for increased surface area, delivering balanced purification ideal for daily driving routines and passing strict annual emission tests.

Metal substrates offer exceptional shock resistance, eliminating the risk of internal fracture common with brittle ceramic cores during rough road conditions. When upgrading, ensure the existing catalytic shell is thoroughly cleaned of carbon residue to maximize contact efficiency of the new coating.

Safety & Technical Reminders

This component requires professional fabrication. Installation demands cutting the existing catalytic housing, precise placement of the internal core, and tight welding seals to prevent air leakage. After reinstallation, always perform a leak check to ensure exhaust gases do not escape toward the vehicle interior.
