The design combines a ceramic substrate with AP Emissions Technologies' ARISTO substrate chemistry and advanced manufacturing methods to deliver efficient loading and consistent converter construction. The stainless steel body and welded flange connections support a durable exhaust repair solution, while the OE-dimensioned layout helps maintain proper alignment during replacement. This part number, 644055, is listed for 2008-2017 Mitsubishi Lancer front applications, with a separate 2009-2011 California-emissions listing also shown in the fitment data.
