Mazda B4000 Catalytic Converter - Magnaflow - Direct-Fit - `07-`09. This direct-fit MagnaFlow catalytic converter is designed specifically for 2007–2009 Mazda B4000 applications to restore proper emissions control and maintain factory performance.
Manufactured using CARB-compliant processes, this converter replicates the OE spun-body design for reliable fit and function. MagnaFlow's use of 3D scanning in development helps ensure accurate mating to stock flanges so installation can be completed without cutting or welding when using the proper tools. The compact, low-mass body and single laser fusion weld reduce potential leak points while promoting thermal efficiency. Included gaskets and hardware simplify installation and help keep your check-engine light from returning when replacing a failing unit.
