Product Details

This MagnaFlow Direct-Fit CALIFORNIA OBDII CONVERTERS part is engineered to replicate the original equipment spun-body layout, helping the converter fit and function like the factory unit on the specified Chevrolet Express 3500 and GMC Savana 3500 applications. MagnaFlow uses 3D scanning during development to match OE dimensions, while the compact low-mass design supports thermal efficiency. Part number 4551535 is built with stainless steel construction and a ceramic substrate for a durable replacement in emissions-controlled service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Check engine light caused by a failed catalytic converter
• Emissions test failure on CARB-regulated vehicles
• Restricted exhaust flow from a deteriorated converter
• Leak-prone factory seals and corroded mounting points
• Fitment issues from non-direct replacement parts
