Cutaway diagram of MagnaFlow catalytic converter

A. MagnaFlow engineers its converters with superior airflow in mind. The large surface area of the honeycomb ceramic catalyst combines with a detailed coating process to allow the most exhaust to flow through the converter. Innovative technology allows each catalyst to both oxidize and reduce harmful emissions.


B. A ribbed body encases the ceramic to reduce expansion and distortion when the converter reaches its high operating temperature. The ribs form channels that hold the ceramic in proper alignment and protect the cushioning mat from direct exposure to exhaust gases.


C. MagnaFlow converters have a smooth-flowing, 1/2" lap joint where the neck and body connect. This joint prevents the neck from extending into the body, where it could impede exhaust flow.


D. MagnaFlow maintains separate dies for several converter body sizes and corresponding neck sizes. This process eliminates the need to adapt neck sizes to make them fit on a single converter body size, which would increase back pressure and decrease airflow and horsepower.


E. The ceramic catalysts are seam welded to a heavy-gauge, stainless steel converter body. Furthermore, a stainless steel heat shield is seam welded to the inner converter body. This style of welding forms a strong bond between the converter's components and prevents the ceramics from shifting.


F. Ribbing on the shield offers a final layer of protection against heat damage while reinforcing the structural stability of the entire converter.


This converter includes a single O2 port. The O2 sensors are sold separately.

These converters worked great. The bugs were right where I needed them to be for the O2 sensors. Very good value.

  • Catalytic Converter for 2006 Volvo V70 2.5L Engine
    The only catalytic converter we have available that is confirmed to fit your 2006 Volvo V70 is the MagnaFlow Heavy Metal Loaded # MF99009HM. This converter does feature a 3 inch inlet/outlet but it does not include O2 sensor ports. The MagnaFlow Stainless Steel # MF94269 that you mentioned may fit with some modification on your Volvo, but I cannot confirm if it will work. It does have the needed 3 inch inlet/outlet and is compatible with your engine size. It includes two O2 sensor ports....

  • Universal Stainless Catalytic Converter With 2 Inch Diameter Inlet And Outlet
    We do offer a universal stainless steel catalytic converter with a 2 inch diameter inlet and outlet. I recommend part # MF99004HM. this converter measures 16 long x 6-1/2 wide x 5 tall. The difference between this converter and the # MF94139 aside from the inlet and outlet diameter is part # MF99004HM does not have an O2 port. This converter is not legal for sale or use in California.

  • 2011 Ford F250 6.2L Universal Catalytic Converter Recommendation
    If the catalytic converter for your truck you need has a 3 inch inlet and outlet with an o2 port welded in the part # MF94139 will fit and work well. The engine size limit for this is 6.2 liter like what you have so this fits in that regard as well.

  • Can a Vehicle Run without Catalytic Converters Installed
    We can't ever recommend you remove emissions related components on a vehicle. If you remove catalytic converters on a vehicle you will end up having Service Engine Soon codes pop on the dash of your vehicle. But to answer your question directly, your vehicle will still run just fine without catalytic converters installed. Cats do not actually help the engine run in any way. All they do is clean up the emissions. The O2 sensors before the cats are what is used for the air/fuel mixture of...

  • Recommendation on a Catalytic Converter With O2 Sensor On the Inlet Side
    The MagnaFlow Stainless Steel Catalytic Converter w/ O2 Port - Universal part # MF94139 has the O2 sensor port hole located on the outlet side of the converter. MagnaFlow does offer converters that will mount the O2 sensor on the inlet side of the converter, but that are made for specific model vehicles. MagnaFlow does offer a universal catalytic converters that have dual O2 sensor ports, like part # MF94169. This converter had 3 inch inlet and outlet tubes and measures 13 inches long...

  • Catalytic Converters for a 2000 Ford Explorer Limited with 5.0 Motor
    Without the O2 sensors in place the 2000 Ford Explorer would run poorly. You would need new ones if the old ones are shot. But one of my coworkers stated that the catalytic converter(s) likely have a clog which would cause the system to run too rich and ignite the fuel that is being dumped into the exhaust. So more than likely you will need to replace the catalytic converters. So it definitely sounds like you need new O2 sensors and new catalytic converters. It could be that the heat damaged...

  • Will Universal Catalytic Converter Fit a Kia Rio if the O2 Port is in a Different Place
    Having the O2 sensor port more on the body of the catalytic converter will work just fine on your Kia Rio. The location of the O2 sensor will not be drastically changed by going to this universal converter.

  • Replacement Catalytic Converters for a 2003 Ford Mustang with the 3.6L V6 Engine
    For starters, let's review the exhaust system on your 2003 Ford Mustang with the 3.6L v6 engine first. From the factory you have a total of four catalytic converters and four oxygen sensors (o2). There are two oxygen sensors directly above the first set of catalytic converters which are called upstream sensors and two oxygen sensors in the middle of the last set of catalytic converters which are called downstream sensors.

    The O2 sensor port on most vehicles points up as it appears in the picture for # MF94139. Heat shields on vehicles are placed so as to protect the vehicle from excessive heat. You usually see them near gas tanks or gas lines or non-metallic body panels.
