1. 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 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. Eliminate P042 Code Error

Before replacing a catalytic converter, please make sure your O2 sensors function properly. Faulty sensors can cause damage to spark plugs, and catalytic converters, and damage your fuel economy.
