Magnaflow Exhaust Systems

Direct Fit Catalytic Converter by MagnaFlow®. If your cat needs replacement, install one that will get you through the smog check and give you more horsepower. This converter will directly replace the factory unit, with little or no fabrication required, and the monolithic honeycomb construction and other features will allow maximum exhaust flow. The Direct Fit Catalytic Converter is available in Pre-OBD II, OBD II, and OEM Grade OBD II configurations.

  • Increases exhaust flow compared to original factory converter
  • Increased exhaust flow allows your engine to make more power
  • Exact replacement with little or no fabrication or modifications required
  • Ribbed body to minimize expansion and distortion, holding the ceramic catalyst in proper alignment
  • Strongest and smoothest flowing inlet and outlet joint of any manufacturer
  • Each inlet tailored to the size of the converter body, for maximum flow
  • Monolithic honeycomb catalyst designed for maximum flow
  • Converter body manufactured from heavy-duty stainless steel
  • Seam welded for a strong, tight bond
  • Aluminized steel or stainless steel ribbed heat shield

  • On vehicles registered outside California, the converter is warranted against construction defects for 5 years and against emissions failure for 25,00 miles
  • On vehicles registered within California, the converter is warranted against construction or emissions check failure for 5 years or 50,000 miles
  • Proudly made in the USA

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.

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.

Note: Always consult emissions regulations before replacing a catalytic converter.

What a Deal
When I brought my car to have a new converter installed at my local mechanic, he wanted 1700.00 including the install. Thinking that seemed too high a price, I did some online searches and came across CARiD.com selling the converter for 550.00, so naturally I purchased it. When I brought it to my mechanic he could not believe the price nor the quality. Anyway he charged 450.00 for the install saving me 700.00. thank you CARiD.co. oh and yes, thanks for the free shipping.

Pretty Happy Customer
I bought this cat for my Accord along with a cold air intake, some headlights and fog lights from CARiD. I'm very happy with it all, my Honda sounds and looks awesome! I had to get a replacement cat because my check engine light started to come on 18 months after I bought it, but it was a no hassle return process and they made it right. I'll continue to buy from CARiD. Can't wait to get my S2000 and get some goodies for it!!
