  • Magnaflow 457899 Features:

    MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 457899 helps keep the check engine light off. DIY installation is easy with the proper tools (no cutting or welding required). With features including mandrel-bent tubing to eliminate flow restrictions and stainless steel construction to resist corrosion, you can have confidence in the quality of this catalytic converter. Using state-of-the-art 3D scanning systems in the design process, the MagnaFlow metrology department ensures this new part to fit and function like the original equipment. This direct-fit catalytic converter is designed specifically for the 2000-2005 Lexus GS300 and interchanges with OE part 17410-46520. Avoid potential exhaust leaks by using the included gaskets to get a proper seal. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.

    MagnaFlow Direct-Fit California Emissions Catalytic Converters are designed to original equipment specifications for easy, bolt-on installation. These converters feature a ribbed body that minimizes expansion and distortion when heated up. The ribs form a channel that protects the cushioning mat from direct exposure to exhaust gases, and they hold the ceramic catalyst in proper alignment. Direct-Fit Catalytic Converts use a monolithic honeycomb catalyst with a ceramic coating that is designed for maximum flow and surface area. The coating method is strictly controlled to maintain exact specifications.

    Note: These catalytic converters are legal for sale in the state of California.
