Its direct-fit layout uses 2-bolt loose flange connections with spherical flare inlets and pipe connection outlets, helping match the original exhaust configuration more closely. The stainless steel body and ceramic substrate support exhaust flow and emissions control in a durable construction.\u003c\/p\u003e\u003cp\u003eThis part cross-references Walker 49977 and 642821 for the same application. The EPA line from Walker focuses on compliant replacement converters for import and domestic OBDII vehicles, and this unit follows that approach with a fitment-specific design. The part number 50578 is also useful when verifying the correct converter for the Mustang application.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a worn or failed catalytic converter\u003c\/li\u003e\n\u003cli\u003eAddressing emissions-related fault codes tied to converter efficiency\u003c\/li\u003e\n\u003cli\u003eRestoring exhaust flow through a damaged converter assembly\u003c\/li\u003e\n\u003cli\u003eCorrecting leaks at flange or pipe connection points\u003c\/li\u003e\n\u003cli\u003eMatching the original exhaust layout on a specific-fit application\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eFitment notes call for an exhaust gasket, and the converter is listed with pre-catalyst and midbed oxygen sensor locations.
