Product Description

The Magnaflow 49058 is an OEM Grade Federal/EPA Compliant direct-fit catalytic converter engineered for the passenger side on the 2003-2011 Ford Crown Victoria, Lincoln Town Car, and Mercury Grand Marquis. This is the passenger-side companion to the Magnaflow 49057 driver-side converter, and together they form a complete replacement pair for these full-size Panther-platform sedans.

Built with a stainless steel clamshell design and continuous seam weld, this converter is engineered for superior thermal insulation and reliable emissions performance. MagnaFlow's 3D scanning during development ensures OEM-like fit, with precisely manufactured flared receivers and O2 sensor port locations matching factory placement for a straightforward DIY installation.

This converter is a good fit for Crown Victoria, Town Car, and Grand Marquis owners in Federal-emissions states replacing a failed passenger-side converter with an OEM-grade direct-fit solution. Because this is a Federal (not CARB) converter, it's not for use or sale in California - check your state's emissions requirements before ordering, and disregard any racing-only disclaimer language you may encounter on individual retailer listings, which appears inconsistent with this part's confirmed street-vehicle application.
