Lexus SC430 Catalytic Converter - Magnaflow - California Grade CARB Compliant Direct-Fit - `07-`10. This MagnaFlow direct-fit catalytic converter (part 5411032) replaces the factory unit while maintaining required emissions compliance for CARB-regulated states.
Engineered for a bolt-in fit, this converter is designed to match OE flow dynamics and fitment for 2007–2010 Lexus SC430 and 2007 Lexus GS430 (OE interchange 18450-50350). MagnaFlow’s R&D process uses 3D scanning to reproduce the OE spun-body geometry, and the single laser fusion weld reduces the risk of leaks. The compact, low-mass design improves thermal efficiency while mandrel-bent tubing preserves OEM-like exhaust flow for consistent engine operation and fuel economy. Essential gaskets and hardware are included to help ensure a proper seal; no cutting or welding is required when replacing the factory unit with matching connections.
