Without Air Tube. If your car needs replacement, install one that will get you through the smog check and give you more horsepower. This converter is part of the exhaust header/manifold assembly, and it will directly replace the factory unit, with little or no fabrication required. The monolithic honeycomb construction and other features designed into the converter will allow maximum exhaust flow. The Direct Fit Catalytic Converter with Header is available in Pre-OBD II and OBD II configurations.

When your catalytic converter requires replacement, you can install a factory-like unit that will let you pass a smog check, or you can install a Magnaflow converter that will pass the smog check and increase exhaust flow. If you want to be legal and get a performance increase, the choice is clear. Magnaflow is a performance exhaust system manufacturer, so they know all the tricks to increase exhaust flow for more power. They've also been producing catalytic converters for 30 years, so they've learned a thing or two along the way. All the exhaust flow knowledge they've accumulated has been packed into the design of this Direct Fit Catalytic Converter.

The heart of the Magnaflow converter is the monolithic ceramic honeycomb catalyst, which is specially designed for maximum exhaust flow and surface area. Magnaflow carefully controls the application of the precious metal catalyst to the honeycomb surface to prevent flow restriction or an emissions test failure. All Magnaflow converters have a ½" lap joint where the neck meets the body, and the neck is formed so it doesn't extend into the converter body where it could hamper exhaust flow. As a result, the Magnaflow converter has a smoother flowing inlet/outlet joint than any other manufacturer. Magnaflow also carefully matches the size of the inlet to the converter body, because putting a larger neck on a smaller body would reduce airflow.

Besides incorporating features that increase exhaust flow for better performance, Magnaflow also builds their converters to last. The converter body is manufactured from heavy-duty stainless steel for maximum durability. All converters are seam welded close to the converter body for a strong, tight bond, not along the edge, which would allow the converter to expand and let the catalyst move around. And the aluminized steel or stainless steel heat shield creates a rigid wall of protection against heat and adds to the structural stability of the converter.

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.

On vehicles registered outside the state of California, Magnaflow warrants the Direct Fit Catalytic Converter with Header to be free of manufacturer's defects for a period of 5 years and emissions failure for 25,000 miles. The Direct Fit Catalytic Converter with Header on vehicles registered in California carries a 5 year, 50,000 mile warranty against manufacturer's defects and emissions failure.
