Description
OEM Grade
Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-029. With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. Designed to fit the 2012-2017 Jeep Wrangler and 2018 Jeep Wrangler JK, this direct-fit catalytic converter also interchanges with OE parts 6808 5119AC and 6808 5119AB. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed Federal emissions requirements set forth by the EPA, complying with legal standards for OBDII Federally registered vehicles with California or Federal/EPA Emission systems.

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.

MagnaFlow direct-fit catalytic converters are designed for easy bolt-on installation for the professional installer. Welding, cutting, and tube-bending equipment are not required. These cats feature a ribbed body that minimizes expansion and distortion when the converters heat 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. MagnaFlow converters use a monolithic honeycomb catalyst; the ceramic coating is designed for maximum flow and surface area, and the coating method is strictly controlled to maintain exact specifications. Improper coating could result in flow restrictions or an emissions test failure. These converters are designed to exact OE specifications and are available for the most popular vehicle makes and models.
