Magnaflow 05-07 Jeep Liberty 3.7L Direct Fit Converter

A failed catalytic converter on a 2005-2007 Jeep Liberty usually means a check engine light and a failed emissions inspection. This MagnaFlow direct-fit replacement (part number 5451186) is built specifically for the Liberty's 3.7L V6 and bolts into the factory location without any cutting or welding. It meets CARB standards and is legal in all 50 states, so it works everywhere from California to Maine.

MagnaFlow constructs this converter with 16-gauge 409 stainless steel tubing and mandrel bends that match the original exhaust geometry. The spun body design with a single laser fusion weld keeps the fit tight and reduces the chance of leaks, while a Torca AccuSeal exhaust clamp provides 360-degree clamping force without distorting the pipe. Hardware is included in the box so you can avoid wrestling with corroded factory bolts and clamps.

This unit interchanges with a range of OE Mopar part numbers including 5212 9078AB through AK and 5212 9439AA through AE, among others. MagnaFlow's development team uses 3D scanning to nail the OE fitment, so the converter drops into the same space with the same hanger locations as the original. It is a direct replacement that keeps your Liberty running clean and in compliance without needing exhaust shop fabrication work.
