Magnaflow 06-09 Jeep Commander 4.7L Direct Fit Converter

When your check engine light comes on and the catalytic converter is the culprit, getting the right replacement for your 2006-2010 Jeep Commander or 2007-2010 Grand Cherokee matters. MagnaFlow's direct-fit catalytic converter (part 5451709) is built to match the factory specs on the 4.7L V8, so it bolts right in without cutting or welding.

MagnaFlow uses 16-gauge 409 stainless steel tubing throughout, which holds up well against corrosion over the long haul. The mandrel-bent tubing keeps the same geometry as the original equipment, maintaining smooth exhaust flow and helping preserve your fuel economy. A single laser fusion weld replicates the OE spun body design, reducing the chance of exhaust leaks at the seams. The compact, low-mass converter body also allows for better thermal efficiency compared to bulkier aftermarket options.

This is a California CARB-compliant converter, meaning it is legal for sale and use in all 50 states, including California, Colorado, New York, and Maine. MagnaFlow's metrology team uses 3D scanning during development to ensure the fit matches OE specifications. The kit includes a Torca AccuSeal clamp that applies 360-degree clamping force to prevent pipe distortion, and gaskets and hardware are in the box so you are not reusing corroded factory parts.

This converter interchanges with over a dozen OE part numbers including 5209 0043AC through 5209 0044AF and several 5212-series numbers. If your Jeep needs to pass emissions or you just want that check engine light gone, this is a straightforward bolt-on solution backed by stainless construction and CARB compliance.
