MagnaFlow 458062 Catalytic Converter

California OBDII Direct-Fit Converter

MagnaFlow 458062 is a California Grade, CARB-compliant direct-fit catalytic converter built for specific GM truck and SUV applications. It is engineered to help keep the check engine light off while matching original equipment fitment for a cleaner replacement on the 2001-2002 Chevrolet Suburban 1500, 2002 Chevrolet Silverado 1500, and related vehicles.

As part of MagnaFlow’s Direct-Fit CALIFORNIA OBDII CONVERTERS line, this converter is built for emissions-controlled applications that require CARB compliance and OE-style installation. The design uses stainless steel construction, mandrel-bent tubing, a spun body layout, and a single laser fusion weld to support leak resistance and thermal efficiency.

• CARB-compliant construction for legal use in California and CARB-restricted states on listed vehicles
• Stainless steel body and tubing for corrosion resistance
• Ceramic substrate with bolt-on inlet and outlet connections
