Description

MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 441021 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 2001-2004 Lexus IS300 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.

Product Overview

MagnaFlow specializes in superior catalytic converter and exhaust technology and has spent the past 30+ years earning its reputation as a global market leader. American engineered and manufactured, MagnaFlow Catalytic Converters combine efficient industrial design to produce a product that exceeds, rather than meets, the highest standards of product performance and efficiency in the industry. MagnaFlow uses both Ceramic and Metallic substrates with different combinations of cell density and wall thickness to meet vehicle specific requirements. MagnaFlow Direct-Fit Catalytic Converters are designed for easy bolt-on installation for the Professional Installer. Each is designed to exact the original equipment specifications. While the majority of the Direct-Fit Catalytic Converter products do not require welding, cutting or bending, limited applications may require additional welding for optimal installation. All Federal catalytic converters meet EPA requirements. Federal Catalytic Converters are not legal for sale, installation or use on vehicles registered in the state of California. All California State Catalytic converters are CARB compliant. Converters in this catalog are based on Executive Orders issued by the California Air Resource Board and must be used in accordance with this information. In California, it is illegal to select a catalytic converter for installation based solely on vehicle weight and engine size. * Stainless steel construction * Formulated for Gas and Diesel Applications
