Check Vehicle Fit

These days, the DIY or do-it-yourself crowd is all about creating custom work and one-off exhausts are no exception. Whether you're working on a classic car, race car or just your daily driver, a MagnaFlow universal converter should be the standard building block for your custom exhaust. Since these items are universal, some modifications may be involved such as cutting or welding.

My 96 Ford F-250 HD 5.8L was wearing it's original exhaust and I was experiencing some lack of power which was thought to be a clogged cataltic converter. As a bolt on "exact fit" converter was hundreds more I opted for this universal fit one at a fraction of the cost. The unit was shorter than OEM which created some concern but I was assured it was designed to handle the exhaust output of my engine. The materials and craftsmanship were excellent and I coupled the converter with a Dynomax Super Turbo muffler and the sound is teriffic, however I have not noticed any boost in engine performance.

Comments about MagnaFlow Universal Catalytic Converter:

I have a 2002 Chevy Trailblazer that was losing a lit of power and got a dianostic code for a faulty catalytic converter. Cound not get the part directly from the store so I decided to irder the part from Advance Auto. It was eady to order a compatible part online. The part actually came a couple days ahead of time. It was in good shape and exactly what I order. I had a lot of fun pulling the old part, a sawsaw made easy work removing the old part. The new part lined up easily. I got my clamps just down the road at my neighbor Advance Auto. The vehicle ran great after the repair.

Comments about MagnaFlow Universal Catalytic Converter:

Magnaflow is not just a brand name. It lives up to its name with this cat. I could have installed it myself but I support my local businesses and had a buddy's shop swap this in for my 140k mi plugged and rattling catalytic converter in my 2000 GMC Jimmy 4x4. I had him do this along with a chambered welded muffler (no fiberglass muffler trash) and my SUV feels muuuuch better. This CAT is not as bulky nor as heavy which weight matters when it comes to mpg. Great product!!! Thanks AAP!

        Bought this convertor to replace the bank 1 convertor on my 2002 Yukon. The body is too long to fit in space available. It should work fine on right side but part description says left side. I would recommend but just not for left side.

          Purchased this to replace an old catalytic converter on a 2000 GMC Sonoma 4x4 with a 4.3 Liter engine. The replacement fit well. Only needed to purchase 3 additional exhaust clamps and a piece of exhuast adapter tubing (2.5" ID x 2.5" OD)to make it fit. The product seems to be good quality. The exhaust smell changed from a sour smell to a barely noticeable one.
