"Matched right up to everything on my 99 Tahoe they look nice and seem better quality than the original ones." posted by: Christo on November 8, 2013

"wrote one review and dished it quiet a bit but also praised it,seems they dont want to post it so im writing another one.you cant call it a bolt on if it doesnt come with bolts,you can only get them from the factory as a whole thing for 2 to 3 times what these cost.the gasket was hard to come by and cost a good bit as you could only get it from the dealer as well....a short trip to the local hardware store and some bolts and a few lock washers later its done and no light as of month 3-4." posted by: evilpea on April 20, 2010 view all 5 reviews

"Product is satisfactory. We were satisfied with the product." posted by: sjt on June 8, 2008

"Who could have thought that shopping for a catalytic converter, could be so easy as 1,2,3. Well, it was. The magnaflow catalytic converter is the best purchase ever. With one entrance, and two escapes, makes the air flow faster. It's practical shape, makes the installation much more easier. What more can I do, other than recommend this piece to others." posted by: pana on December 17, 2007

"great fit ! excellent performance. easy installation. nicely built product. would purchase again . Used magnaflo before on a truck I had before this one . same great performance. love the two piece system because it was easy to align on flanges of manifold and have tight seal. no vapor leaks !" posted by: giovanni on December 12, 2012

"Very easy install took around 30 mins. just had to weld down pipe from manifold and bolt it up. Has a lot more flow that stock converter and coupled with Gibson exhaust have noticed more torque as well as small mpg. gain" posted by: Irish on April 18, 2010 view all 15 reviews

"Had it installed quick and easy at the shop. It is a universal converter so it doesnt come with mounting flanges no universal does. You have to take it to a professional as there is cutting and welding involved to fit but thats what makes a universal cheaper. If you want a more do it yourself then get a direct fit converter. I went universal for the savings and it does the job just fine." posted by: Kyle on August 10, 2012

"The 'minor modifications might be required' in the description of this item cost me an additional sixty dollars in labor and parts by a muffler shop. Had I walked away from the shop to call or write to Autopartswharehouse, my engine would have still been in peril due to further delay. 'Performance' is not rated. It takes time to determine a part's performance. How long it lasts counts." posted by: Lengo on May 30, 2012

It's true that when they first came out, catalytic converters were cumbersome, power-sucking devices that weren't all that efficient at doing what they were supposed to do. Clean-air technology has come a long way in the past thirty years. While eliminating the catalytic converter on the race track could make the difference between first and second place, one the street, it's not an issue - especially when you have a Magnaflow Catalytic Converter installed. Magnaflow is a company that specializes in high performance exhaust systems, and the Magnaflow Catalytic Converter is designed with high performance in mind. This catalytic converter cleans your exhaust by recombining deadly carbon monoxide and nitrous oxide compounds at the atomic level into less harmful gases, and achieves this while maintaining the least restrictive flow of exhaust gases. Especially designed for each application, a Magnaflow Catalytic Converter will install easily without any modifications to your vehicle's current exhaust system necessary. As you know, exhaust components are subject to the worst conditions of anything on the vehicle because of their location. Magnaflow's Catalytic Converters are made from aluminized steel or stainless steel, able to stand up to anything. They also pass California OBDII standards, so you know you're getting the best. Gearhead hobbyists should always get outstanding customer assistance when they buy dependable automotive parts. For all our customers, we built a round-the-clock technical assistance bureau to support all your needs. Nobody likes to pay for shipping, so all parts come with completely free shipping for all orders at least $50. If you can find a better price, let us know - we will beat any price advertised elsewhere.

Overall Rating 4.5

Driving at high speed, you noticed that your vehicle is quickly losing its power, and your engine is running hotter than usual. The rattling sound from underneath your vehicle didn't seem to faze you, but the rotten-egg smell sent you to panic mode. Could it be that your catalytic converter is damaged? Most likely, it is already beyond repair, and you need to replace it right away. We tested the Magnaflow catalytic converter on our 1997 Jeep Cherokee SUV to help you determine whether this cat con has what it takes to restore the life out of a battered exhaust system.

Features

  • From the Magnaflow 53100 series
  • For front, driver, or passenger side installation
  • Stainless steel case and tube
  • Round, ribbed body
  • Measures 8 inches by 5.13 inches by 12 inches
  • Ceramic honeycomb catalyst substrate
  • 49-state legal
  • Natural finish
  • With single two-inch inlet and outlet
  • Sold individually
  • Requires minor vehicle modification
  • Comes with lifetime Magnaflow limited warranty
  • Compatible with most vehicle makes and models

What we liked

  • The Magnaflow catalytic converter was very easy to install. It took us less than an hour to bed in this new cat con.
  • This catalytic converter sounds quieter than stock. We didn't notice any hollow sounds from the underside of our Jeep.
  • Compared to other catalytic converters of the same caliber, this one from Magnaflow offers more bang for the buck.
  • Our Jeep performs a lot better with this cat con installed. The backpressure has been kept to a minimum.

What we didn't like

  • It's not legal for use in California. If you live in that state, you might find yourself in hot water with traffic enforcers if you use this catalytic converter. However, you can still find other Magnaflow cat cons that are CARB-compliant.
  • The Magnaflow catalytic converter requires a little bit of welding. It's not for anyone who wants a snap-on-and-forget type of cat con. If you're not comfortable handling a DIY-welding job, you can look for a catalytic converter that bolts on directly to the vehicle.

Our final say

The Magnaflow catalytic converter is for anyone who's looking for a high-performance cat con for his or her vehicle. Most catalytic converters are priced exorbitantly and are compatible with only certain vehicle types. This one fits most budgets well, considering that it's built for performance. However, newbie DIYers may find it a tad difficult to install because it needs to be welded in place.
