Magnaflow 2008 Jeep Liberty 3.7L Direct Fit Converter

MagnaFlow builds part number 5451187 as a California CARB-compliant direct-fit catalytic converter for the 2008 Jeep Liberty 3.7L and the 2007-2008 Dodge Nitro 3.7L. Both vehicles share the same exhaust system architecture for this converter position, which is why one part number covers both applications.

Like other MagnaFlow direct-fit converters, this unit is developed using 3D scanning to match the factory dimensions precisely. That means no cutting, welding, or fabrication during installation. The converter body uses 16 gauge 409 stainless steel tubing with mandrel bends, and the spun body is sealed with a single laser fusion weld. The barbed exhaust hangers are made from corrosion-resistant 410 stainless steel to help reduce vibration and noise. MagnaFlow joins everything with 308 stainless steel MIG welds and includes a Torca AccuSeal clamp plus hardware so you do not need to reuse corroded factory parts.

The precision stamped collector design inside the converter maintains proper flow dynamics. This converter is legal for sale in all 50 states and meets CARB requirements for California and other regulated states.
