MagnaFlow California 40000 Catalytic Converters

5.0 out of 5 stars 1 Customer Reviews

MagnaFlow California 40000 catalytic converters are the first series in a new line of converters designed for vehicles with second-generation OBDII systems. Designed, tested, and catalogued for specific vehicles, these are not traditional universal converters. These converters have higher efficiency than conventional strict California requirements for conversion efficiency and durability, and most are direct-fit requiring no bending, cutting, or welding.
