Product Line Details
The 3in. Universal California OBDII Catalytic Converter line by MagnaFlow is engineered to comply with California OBDII emissions requirements. This product line focuses on universal fitment options that accommodate a range of Ford trucks and vans, providing a balance of durability and emissions control. The stainless steel construction and ceramic substrate are standard features across this line, ensuring consistent catalytic performance and resistance to harsh exhaust conditions.
Detailed Product Description
This catalytic converter features a 3-inch inlet and outlet diameter, making it suitable for exhaust systems requiring this size. The clam shell body shape measures 22.5 inches in length, 7.75 inches in width, and 7.5 inches in height, providing a compact yet effective design. The stainless steel body and tube material offer enhanced corrosion resistance, while the attached heat shield helps protect surrounding components from excessive heat. The ceramic substrate inside facilitates the conversion of harmful exhaust gases into less harmful emissions. This converter is universal and compatible with Ford models such as the E-150 Econoline, E-350 Econoline Club Wagon, Excursion, F-250 HD, and F-350 Super Duty, among others.
Common Applications and Issues Addressed
- Replacement for failing or clogged catalytic converters on Ford E-150 Econoline and F-250 Super Duty vehicles
- Helps resolve emissions test failures related to catalytic converter efficiency
- Reduces exhaust emissions to meet California OBDII standards
- Addresses exhaust leaks caused by damaged or corroded catalytic converters
- Improves exhaust flow and engine performance by restoring proper catalytic function
Installation Notes and Tips
This catalytic converter requires new hangers for mounting, which are not included. Mounting hardware and gaskets are also not included, so ensure you have the necessary components before installation. The converter is designed for universal fitment, but verify compatibility with your specific Ford model and exhaust system configuration. The attached heat shield should be handled carefully during installation to avoid damage. Air tubes are adaptable and included, but sensor ports are not present on this model.
