Frequently Asked Questions
Will this Magnaflow product fit my 1997-1999 Acura CL?
That vehicle range is listed for this exact part number, but confirm the engine, body configuration, emissions package, factory exhaust layout, and every current Magnaflow application note before ordering.
Is this catalytic converter legal for my vehicle and registration state?
Converter legality depends on the exact vehicle, engine, emissions package, registration state, certification, and test group. Match every current Magnaflow application and emissions note before ordering.
Does a direct-fit converter require cutting or welding?
A true direct-fit converter is designed around factory connection points, while a universal converter normally requires fabrication. Follow the instructions for this exact part number and inspect all flanges, sensors, gaskets, and clearances.
Installation Instructions
Follow the current Magnaflow instructions and vehicle service information for part number 51204. Work on a cool exhaust, support the vehicle safely, confirm all interfaces and clearances, align and support the complete assembly before final tightening or welding, test for leaks, and inspect the installation again after the first heat cycle.
