Lexus GS430 Catalytic Converter - MagnaFlow - California Grade CARB Compliant Direct-Fit - 2007. This MagnaFlow direct-fit catalytic converter is built to replace the factory unit on 2007 Lexus GS430 models, offering CARB-compliant emissions performance and OE-style fitment.
Engineered with a spun-body design and mandrel-bent inlet/outlet tubing, this converter replicates original flow characteristics to help maintain factory performance and fuel economy. Constructed from corrosion-resistant 16-gauge 409 stainless steel with a single laser fusion weld, it reduces leak points and improves thermal efficiency through a compact, low-mass design. Included gaskets and hardware simplify installation—no cutting or welding required when installed with proper tools. MagnaFlow’s use of 3D scanning in development helps ensure accurate fit and interchangeability with OE part 18450-50350. This unit is legal for sale in all 50 states, including California, when the converter’s Executive Order (EO) number and Engine Family Number (EFN) match the vehicle.
