Product Details

Direct Fit 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.

Replacement that actually works
Had to replace the stock exhaust manifold on my 2002 IS300 after the original cat went bad. Direct fit, bolted right up. No CEL after install, which is a win. Not cheap but Magnaflow makes quality stuff, and way better than dealing with codes headaches.

Fits like a glove
Perfect so far, it fit like factory. The light is gone car runs smoother than ever. The stainless steel construction feels durable. It also resolved a minor exhaust leak I had near the old manifold. Definitely recommend, it's a good replacement.

Great Replacement
The first thing I noticed when I unboxed this manifold was how well made it is. The welds are clean and the stainless steel feels durable. The gaskets included were great quality. Once installed, no more rattling or check engine light, and the car feels more responsive.

Product Resolved P0420 Code.
I received this catalytic converter in the mail today. The three bolts included (probably intended to hook the converter to the exhaust pipe) were a bit short and didn't have corresponding nuts, so I used three M10-1.25 bolts that I bought at Home Depot with one washer each to prevent the locking head from biting into the exhaust. The product was a bit greasy and the welds looked substantially different than they do in the stock photo, but they were much higher quality than OEM. I'll update the review for this catalytic converter if it fails within the next couple years.

Excellent!!
Order this part because my truck catalytic converter was stolen. It arrived right away, installation was quick everything fit perfectly and sounds great. The hardest part was connecting to the headers because you got to reuse the hardware, it doesn't come with bolts and nuts. Great product!

Fixed my check engine light
Kept getting that P0420 code on a 2013 honda accord. Swapped this in bolted right up like factory no issues there. Car feels like it's breathing better now

Good Part, Fitment Is Off.
This part performs great but the mount points are a bit off. The hang bar is probably a few inches closer to the underside than it should be making lining up everything a pain, and it's forcing the rubber off to one side pretty badly. It also seems like meeting up with the manifold cat is pretty tight. The flexible part doesn't have much wiggle room so I'm somewhat worried it may wear out pretty quickly. Honestly don't regret getting it, just that install is somewhat difficult.
