Product Details

Direct Fit OEM Grade Catalytic Converter with Header by MagnaFlow®. If your car needs replacement, install one that will get you through the smog check. 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 Direct Fit Catalytic Converter with Header is available in Pre-OBD II and OBD II configurations.

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 Ceramic 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 California State Catalytic converters are CARB compliant. Converters 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.

The Direct Fit Catalytic Converter is an exact replacement for your stock converter, with an interface at either end that will allow it to be bolted into the exhaust system. No fabrication or modifications are usually required. It’s available in OBD II (On-Board Diagnostics, 2nd Generation), Pre-OBD II, and OEM Grade OBD II configurations. Pre-OBD II is for early vehicles (generally 1995 or older), which were equipped with 2-way, 3-way, or 3-way with air injection converters. Two-way converters oxidize harmful Hydrocarbons (HC) and Carbon Monoxide (CO) along with secondary oxygen into water (H2O) and Carbon Dioxide (CO2). Along with the previously detailed conversion, a 3-way converter also reduces oxides of nitrogen (NOx) into Nitrogen (N2). The 3-way with air injection converter operates the same as a 3-way converter but with the addition of air pumped into the converter to improve the oxidation capabilities.

OBD II converters are for 1995 and newer vehicles and are 3-way converters. OEM Grade OBD II converters are for vehicles registered outside of the state of California, with California spec emissions. More precious metals are applied to the substrate on these converters to further reduce emissions. To determine if this converter is right for your vehicle, find the VECI (Vehicle Emissions Control Information) label in the engine compartment and look for the word “California” on the label.

On vehicles registered outside the state of California, MagnaFlow warrants the Direct Fit Catalytic Converter to be free of manufacturer’s defects for a period of 5 years and emissions failure for 25,000 miles. Direct Fit Catalytic Converters on vehicles registered in California carry a 5 year, 50,000 mile warranty against manufacturer’s defects and emissions failure.

Back on the Road Without the Dealer Prices
Was stressing hard when my check engine light came on because I know converters are pricey. Found this one and it was a direct fit for my Forte. Saved a ton compared to the dealer's quote. Worth every penny

Fair Fit, Performs Great
Was a pretty easy install. Mounts fine to the block and to my other Magnaflow cat down below. Has bolt mounts for the old cover. Performs great! Only thing I thought was odd is the lack of several mounting spots. Reusing the old heat cover only has two bolts where stock uses 4. And the only way it's held on to the engine is to the block itself where stock has two more bolts down towards the lower end on the block. Plus there's a secondary heat shield that goes around the stock cat where on this there are no bolt holes for that shield at all. Really this isn't necessarily a problem but it would have felt better if I could have at least mounted the whole thing to the engine with those two lower bolts and the top heat shield a bit better.

MagnaFlow Catalytic Converter
Item was as described. Very easy installation, For anyone who has an 07-09 Camry 2.4 L Just make sure you remove the Alternator to get to the one header bolt. Other than that it was easy and the performance is much better than the factory.

Catalytic Converter
This unit was purchased to replace a clogged catalytic converter on a 2009 Pontiac G6 4-cylinder engine, where the converter is built into the exhaust manifold. Product fit Ok and came with gaskets, which was a plus. On the OEM unit, the heat shield bolted to the exhaust manifold and there was no place to make this connection with the Magnaflow unit. The heat shield also had to be bent some to be reinstalled at all. The OEM unit had threaded holes for the heat sink bolt and other attachment points. The Magnaflow had these connection holes, but they were not threaded and I had to search for bolts to use as the OEM bolts could not be reused. It was the same with attaching the manifold to the exhaust pipe. The OEM unit had studs threaded into it and the Magnaflow just had drilled holes, which I had to find bolts to fit, which of course was not expecting and did not have any readily available, which extended the installation time. Overall, it worked OK. I don't think they should call it a direct fit until they fix these little issues. Including bolts would have been extremely helpful and saved me a lot of time.

Perfect Fix for My Accord
Put this on my 2018 Accord, cleared the error code and drove it for a week - still no issues. The car is running like new and I'm really happy with this purchase.
