Magnaflow 09-12 Jeep Liberty 3.7L Direct Fit Converter

A bad catalytic converter on your Jeep Liberty or Dodge Nitro means a persistent check engine light and a failed emissions test. MagnaFlow 5551148 is a CARB-compliant direct-fit replacement that covers the 2009-2012 Jeep Liberty and 2009-2011 Dodge Nitro, both with the 3.7L V6.

Factory-Matched Fit

MagnaFlow develops their direct-fit converters using 3D scanning to replicate the original exhaust geometry. That means this converter drops right into your existing exhaust system without cutting or welding. The mandrel-bent tubing keeps the internal diameter consistent through every bend, and the OE-sized barbed exhaust hangers made from 410 stainless steel help reduce noise and vibration.

Durable Stainless Construction

The converter body uses 16-gauge 409 stainless steel tubing with 308 stainless steel MIG welds. The spun body design and single laser fusion weld keep the seam sealed tight, while the precision stamped collector maintains efficient exhaust flow.

Interchanges with Factory Part Numbers

This converter interchanges with OE parts 5212 5351AD, 5212 5351AE, 6805 2257AA, 6805 2257AB, and 6810 5776AA. If your shop quotes one of those part numbers, MagnaFlow 5551148 is the replacement.

Legal in Every State

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

For Liberty and Nitro owners dealing with emissions issues, this MagnaFlow converter gets you back on the road with a factory-like fit and full compliance.
