Overview

Built for the 2003-2005 Lexus GX470 4.7L, this converter carries the catalyst load that newer OBD-II systems expect. MagnaFlow's OEM Grade 49339 is built for exactly that job and bolts in without cutting or welding. Coverage spans 3 model years: 2003-2005 Lexus GX470 (Base) and 2003-2004 Toyota 4Runner (Limited, Sport, SR5). This is the driver-side converter position, so match it to the unit you are replacing. It ships at roughly 9 lb.
