MagnaFlow California Grade Rear Catalytic Converter - Lexus RX300 1999-2003

This is MagnaFlow's California Grade CARB compliant direct fit converter for the RX300, a stainless steel assembly with free flowing mandrel bent tubing that installs with ordinary hand tools, no cutting or welding needed. A single laser fusion weld reproduces the OE body while cutting the number of potential leak paths, and the compact low mass design helps the converter reach operating temperature quickly. It measures 12.75 in overall with a flange inlet and a pipe connection outlet, ships with one donut gasket, and interchanges with OE parts 17420-20130, 17420-20250 and 17420-20290. CARB Executive Order D-193-171 covers it for legal installation in California and other CARB states on the vehicles listed below.
