The MagnaFlow OEM Grade Direct-Fit Catalytic Converter 49507 is the rear converter for the 1999-2003 Lexus RX300 3.0L and 2001-2003 Toyota Highlander 3.0L. Its spun 409 stainless steel body carries a ceramic monolith substrate and installs without cutting or welding using the included gaskets and hardware. MagnaFlow replicates the OE spun body design with a single laser fusion weld to reduce leak points and keep the check engine light off. It interchanges with OE parts 17410-20201 and 17410-20390. This is a Federal / EPA compliant converter and is not legal for sale or installation in California, Colorado or New York.
