High Temp Resistant 300 Cell Catalytic Converter With Stainless Steel E5

The KSRCAT 117×100mm metallic catalyst core restores compliant exhaust cleanliness while preserving engine torque across everyday driving conditions.

Constructed from high-strength rolled stainless steel honeycomb, this 300 CPSI converter substrate outperforms fragile ceramic inserts that shatter under road vibration or extreme thermal cycling. The measured 300-cell architecture establishes an optimal middle ground between unrestricted airflow and chemical conversion density, ensuring your throttle response remains intact while carbon monoxide, hydrocarbons, and nitrogen oxides break down efficiently. A dedicated E5-formula precious metal washcoat delivers stable tailgas treatment, helping gasoline passenger cars and light commercial vans consistently pass European emission inspections. The precise dimensional profile eliminates guesswork, enabling straightforward cut-out and weld replacements directly into standard factory housings without secondary machining.

Benefits & Practical Tips

• Align the exact 117×100mm footprint to bypass custom grinding and significantly reduce workshop re-fit labor.
• Remove all slag, carbon buildup, and residual moisture before seating the new core to preserve catalyst adhesion and extend service life.
• Perform a gentle heat-soak drive immediately after installation to burn off protective oils and stabilize all weld joints against thermal stress.

Installation & Care Reminders

This component requires professional exhaust fabrication expertise. Extract the failed legacy carrier completely, degrease the housing interior, center the replacement substrate precisely, and execute continuous perimeter welds to eliminate all exhaust gas leaks. Monitor downstream oxygen sensor voltage after assembly to verify steady E5 feedback control. Avoid high-load cold starts until the substrate reaches designated operating temperature.
