This is MagnaFlow's HM Grade front converter for the 3.0L inline six, a spun body unit with a precision stamped collector that replicates the OE design and installs with no cutting or welding. The tubing is 16 gauge 409 stainless mandrel bent to hold the OE flow geometry, joined by a single laser fusion weld that leaves fewer seams to leak, with 308 stainless MIG welds and OE-sized barbed 410 stainless hangers to keep noise and vibration down. It carries no oxygen sensor ports and ships with three flat ring gaskets. Compliance is the thing to read carefully here: it is built to meet or exceed Federal EPA requirements for OBDII vehicles registered under Federal emissions systems, and it is New York certified, but it is not CARB certified and cannot be sold or installed in California or Colorado.
