California OBDII Catalytic Converter

MagnaFlow 5451306 is a 2.50-inch universal California Grade catalytic converter built for CARB-compliant replacement use on listed vehicles. It uses a stainless steel spun-body design with a ceramic substrate to support corrosion resistance and thermal efficiency, while the welded construction helps reduce leak points.

For drivers searching for a California OBDII catalytic converter for a 2007 Jeep Grand Cherokee or a 2008 Chevrolet Silverado 1500, this universal weld-on converter is listed for a wide range of left, right, and N/A positions on approved applications.

Key Features

• Universal fit design with 2.50-inch inlet and outlet diameters
• Stainless steel body and tubing for corrosion resistance
• Round, clam shell body with compact 13-inch overall length
• Ceramic substrate for emissions conversion performance
• Weld-on inlet and outlet connections; cutting and welding required

Product Details

This MagnaFlow California Grade universal catalytic converter is engineered for emissions-system replacement where a 2.50-inch weld-on converter is required. The spun stainless steel body and single laser fusion weld are used to improve durability and reduce the chance of exhaust leaks, while the low-mass design supports faster heat-up for efficient operation. MagnaFlow 5451306 is listed for multiple Jeep, Chevrolet, GMC, Cadillac, Ford, Dodge, Buick, GMC, and Saturn applications, including 2004-2010 vehicles such as the Jeep Commander, Jeep Grand Cherokee, Chevrolet Tahoe, and GMC Sierra 1500.

This part cross-references Walker (e.g., 16337, 16338) for the same application.

What It Helps Address

• Check engine light caused by a failed catalytic converter
• Emissions test failure related to converter efficiency
• Corrosion damage in the exhaust stream
• Exhaust leaks at the converter body or seams
• Replacement needs on CARB-regulated vehicles with 2.50-inch exhaust connections

Installation Notes

Installation requires cutting and welding, so the converter must be positioned and fabricated to match the vehicle’s exhaust layout. Verify the listed year, make, model, position, and engine family before installation, especially on applications such as 2008-2010 Jeep Commander, 2007-2009 Chevrolet Silverado 1500, and 2007-2008 GMC Yukon. Because this is a universal weld-on converter, proper alignment and exhaust sealing are critical for a correct repair.

Quality Assurance

MagnaFlow 5451306 is built to meet or exceed California Air Resources Board requirements and has undergone additional CARB compliance testing for legal use on the listed vehicles in California and other CARB-restricted states.
