About the MagnaFlow Conv DF Y-Pipe Assy

This is a MagnaFlow OEM Grade direct-fit catalytic converter, part number 49709. It is designed to replace the original on the 2005-2010 Jeep Grand Cherokee and the 2006-2010 Jeep Commander. It is built to meet or exceed Federal emissions requirements set by the EPA.

The converter has a spun body design that replicates the original equipment, with a single laser fusion weld to reduce the chance of leaks. The tubing is free-flowing and mandrel-bent, and the construction is corrosion-resistant stainless steel. The design is compact and low in mass for greater thermal efficiency.

MagnaFlow used 3D scanning during development so the part fits and functions like the original. Installation needs no cutting or welding and can be done with the proper tools. Hardware is included, so you don't have to reuse corroded factory parts.
