Toyota 4Runner Direct Fit Catalytic Converter - Driver Side Rear - Magnaflow - HM Grade - 05-09. A direct-fit, federally compliant replacement designed to restore proper emissions control and maintain factory exhaust flow on 2005–2009 Toyota 4Runner (also fits 2005–2009 Lexus GX470).
This MagnaFlow HM Grade direct-fit converter replicates OE spun-body geometry for reliable fit and function without cutting or welding. It uses mandrel-bent tubing and corrosion-resistant stainless steel to retain OEM-like flow characteristics and thermal efficiency. The single laser fusion weld reduces leak points, and included gaskets and hardware help ensure a proper seal during installation. Designed to interchange with OE part numbers 17450-50121 and 17450-50120, this unit is built to meet Federal/EPA emissions requirements for OBDII federally registered vehicles.
