Maximum Efficiency for Exhaust Flow Internal honeycomb ceramic substrates have a porous structure to increase the reaction area and ensure sufficient catalysts (Pt, Rh, Pd) on the coating surface for a higher conversion rate. 2. Stainless steel shell, Durability Adopts a heavy-duty T409 stainless steel shell that highly resists heat, rust, and corrosion for longer service life, with no worry about bending or melting even in extreme conditions. 3. EPA Federal Standard Certificated All YITAMOTOR catalytic converters are stamped with an exclusive EPA number on the shell. YITAMOTOR offers a 5-year or 50,000 miles limited warranty, for any manufacturer defect. 4.
