Overview

On the early Mazda 3 with the 2.3L, the catalyst lives at the end of a long tubular header that runs from the head down to the front pipe. MagnaFlow 5531344 replaces that whole piece on 2004-2005 S and SP23 models and is legal in California and other CARB states under EO D-193-175. It interchanges with a long list of Mazda OE numbers in the L328-20-50X and LF13-20-50X families, so it covers the running changes Mazda made over those two years.
