2005 Chevrolet Express Van - MagnaFlow Heavy Metal Loaded, Stainless Steel Catalytic Converter - Universal

  • Federal Emissions
  • No O2 Port
  • Universal Fit
  • No Air Tubes
  • Heavy Metal Loaded
  • Non-Spun Construction
  • MagnaFlow

MagnaFlow ceramic catalysts have large surface areas to speed up the exhaust breakdown process while a ribbed, stainless steel body and external shield further protect them. Universal design. Not CARB compliant.


Features:

  • Ceramic catalyst engineered for maximum airflow
    • Honeycomb design and a thick, detailed coating process allow the converter to break down as much exhaust as possible
    • Greater concentrations of catalytically active materials set it apart from other converters by increasing the volume of chemical reactions that break down harmful gases
  • Ribbed body encases the ceramic to reduce expansion and distortion when the converter reaches its high operating temperature
    • Ribs form channels that hold the ceramic in proper alignment
  • Heavy-gauge, stainless steel shield is seam welded to the body
    • Forms a strong bond to prevent the ceramic from shifting
    • Includes ribbing as a final layer of protection against heat damage
    • Reinforces the structural stability of the entire converter


Specs:

  • Overall dimensions: 16" long x 6-1/2" wide x 5" tall
    • Body length: 12"
  • Inlet/outlet diameter: 2-1/2"
  • Inlet/outlet position: center/center
  • Engine size: 6.2L EPA
    • Not legal for sale or use in California
  • Test weight: 6,375 lbs
  • Converter shape: oval
  • Converter function: OBD-II
  • Limited lifetime warranty


Note: This product cannot be shipped to or used in California, Colorado, Maine, or New York.


Cutaway diagram of MagnaFlow catalytic converter

A. MagnaFlow engineers its heavy metal converters with maximum airflow in mind. The large surface area of the honeycomb ceramic catalyst combines with a thick, detailed coating process to allow the most exhaust to flow through the converter. In contrast with most converters, these heavy metal converters contain greater concentrations of catalytically active materials, thereby increasing the volume of chemical reactions that break down harmful gases. 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.

  • Replacement Catalytic Converter Recommendation for 2006 Volkswagen Jetta 2.0T GTI
    We have a direct fit cat that will work on your 2006 Volkswagen Jetta GTI 2.0T that would be the much better option. For that we have the part # MF99006HM that will weld right in place of your current one. Or we have the entire catted section of your exhaust that is part # MF49165. That being said the inlet/outlet of the # MF91066 that you referenced matches the custom fit option I first mentioned so it would fit in that regard. It is a few inches shorter though.

  • Installation and Compatibility of Catalytic Converters for 1999 GMC Savana Van
    The replacement catalytic converter fits for your 1999 GMC Savana Van will depend on where you live and which van version you own. You can use the linked page to select either Federal or California emissions standards to then see converters that are approved. Next use the drop-down menu bar to select the van version you have. We offer both direct-fit and universal converters, some with single O2 ports and others without ports. For example if you do not live in California and have a 5.7L...

  • Which Way Should the Arrow Point on a Catalytic Converter
    The arrow on your catalytic converter should be aligned with the direct of flow for exhaust gases. Therefore, the arrow would need to be pointed towards the muffler, not the header/exhaust manifold.

  • What Precious Metals are Used in MagnaFlow Heavy Metal Catalytic Converter
    Normally the metal catalyst used in a catalytic converter is made with precious metals such as platinum, rhodium and/or palladium. The part # MF99006HM has twice the amount of these metals than the standard style of converter like it. In some cases, cerium, iron, and manganese and nickel are also used.

  • OBD-II Fault Code 0174 in 1996 Ford Explorer with 4.0L V6 Engine in California Vehicle
    The OBD-II fault code 0174 means that the fuel system is operating in a too-lean condition. This means the engine generates more pollutants. The most common causes for this are 1) a plugged fuel filter or weak fuel pump; 2) plugged or dirty fuel injectors; 3) a bad mass airflow sensor (MAF); 4) software that needs to be updated and 5) a vacuum leak (intake manifold gaskets, vacuum hoses, PCV hoses, etc). The two cat kits we offer for your 1996 Ford Explorer 4.0L V6 are MagnaFlow parts...

  • Can I Replace Only One Catalytic Converter on 2006 Ford F150
    I spoke with my contact at MagnaFlow and he does not recommend bolting the catalytic converter in place. The application is designed to be welded and will not have any bolt holes. It is not not necessary to replace both catalytic converters if only one of them needs replacing because the converters work independently of one another. You can certainly use the OEM muffler and pipes that are currently on the truck. The converter will sit in front of the converter so you can keep your stock...

  • Are Catalytic Converters Directional
    The P0420 DTC you mention means that one or both of the catalytic converters isn't operating as efficiently as it or they should be. Catalytic converters aren't usually directional, but if the converter has the port for the o2 sensor built into it, and if the converter's been reversed so that the downstream sensor is sitting upstream of the converter, it would explain why you're getting the DTC.

  • Aftermarket Catalytic Converter Fits for V8 and V6 Versions of the 1996 Ford Explorer
    I linked our available aftermarket catalytic converters for each of the two versions of the 1996 Ford Explorer, V8 and V6, so you can see that these two engines require different parts. The V8 can use parts # MF23311, # MF23312, # MF23310 and # MF99005HM. The V6 uses either part # MF99006HM or # MF23313.

  • Catalytic Converter Options for a 1998 Ford Explorer with 4.0 Liter Motor
    If you live in California you would need to have the CARB compliant catalytic converter. If you live in any other state you can use the 49 state converters. For a California model on a 1998 Ford Explorer with the X designation in the VIN use # MF447206. Check the 8th digit of the VIN. For 49 state converters use # MF23315 for direct fit and E designation. Use # MF23313 for direct fit with X designation. Or you can use universal converter # MF99005HM for E designation or # MF99006HM for...

  • Catalytic Converter Options for a 2006 GMC Yukon XL 2500 6.0 with Police Package
    You will want to look at the direct fit catalytic converter options for your 2006 GMC Yukon XL 2500 6.0. Direct fit will use the factory hangers and will match up to the rest of the exhaust better than universal fit items. Stainless steel and ceramic construction are the highest quality. For your vehicle those include # MF49667, # MF49668, # MF49643, and # MF49642. All of these options do have sensor ports before and after the cats. The positions might not be exactly the same as the stock...

  • What Way Should I Install My Catalytic Converter on My 2017 Jeep Wrangler?
    If you have a MagnaFlow catalytic converter such as the MagnaFlow Heavy Metal Loaded, Stainless Steel Catalytic Converter # MF99006HM, it can be installed in either direction. If the converter can only be installed one way, there will definitely be markings to indicate it. The marking could be either an "out" arrow or an in/out flow marking. I went ahead and attached an article that you may find helpful.
