Magnaflow 11-14 Ford Mustang 3.7L Direct Fit Converter

Your 2011-2014 Mustang's 3.7L Cyclone V6 is a solid engine, but when the catalytic converter goes bad, you need a replacement that fits right and keeps you legal everywhere. MagnaFlow 5561977 is a CARB-compliant direct-fit catalytic converter built specifically for this application.

Designed for the S197 Mustang

MagnaFlow uses 3D scanning to match the factory exhaust geometry of the 2011-2014 Mustang V6. That means this converter bolts directly into the existing exhaust without cutting or welding. Mandrel-bent tubing maintains a consistent internal diameter through each bend, so exhaust flow stays smooth and your engine breathes the way Ford intended.

Solid Stainless Build

The converter body is 16-gauge 409 stainless steel tubing, joined with 308 stainless steel MIG welds. The spun body design with a single laser fusion weld keeps the seam tight to prevent leaks, and the precision stamped collector maintains proper exhaust flow for fuel economy.

Two Torca Clamps Included

MagnaFlow includes two Torca AccuSeal exhaust clamps with this converter. These clamps distribute clamping force evenly around the full 360 degrees of the pipe, preventing the distortion that can lead to exhaust leaks down the road.

Legal Everywhere

CARB-compliant and legal for sale and installation in all 50 states, including California, Colorado, New York, and Maine. Verify your Mustang's Executive Order and Engine Family Number match before installation.

Get your Mustang back to passing emissions with a converter that fits like factory and carries full CARB compliance.
