2007 Rubicon - Aaron83s
Installation Time: Afternoon
excellent cats
I purchased this cat system replacement because my 07 cats were bad, was pretty easy to throw on along with new sensors. we had to cut the old one out, but no problem. new one went on without a hitch, soaked all bolts with pb blast for a few days, and whamoo! new exhaust!! paired with magna flow duel tip street series muffler. sounds great, low rumbel, but not obnoxious. and best yet, no engine lights, been running it 500 miles so far

2013 Wrangler - AnthonyZ.
Installation Time: Afternoon
Fit and finish good.
This Cat is on par with other Magnaflow products that I own. I replaced the Cat when replacing the entire exhaust system. I replaced the O2 sensors as well. Removal and installation of front fender and inner fender took longer than the Cat replacement. I recommend using anti-seize on all hardware.

2013 Wrangler - AnthonyZ.
Installation Time: Afternoon
Fit and finish good.
The Cat build quality is on par with other Magnaflow products that I have owned. The removal of the front fender and inner took longer than the Cat replacement. I replaced the O2 sensors at the same time. I replaced the Cats as I was replacing the whole exhaust system. Recommend using anti-seize on all mounting hardware.

OEM replacement
Took longer to get the old one off due to seized flange bolts. Major power and performance. Engine has 213000 mile and now it runs like new.

Fits, more (not less).
The flange for the Cat was thicker than the original, which required some reworking.

2016 Wrangler - Swyck
Installation Time: Afternoon
Almost good
Build quality is really poor. Some of the worst welding I have ever seen. These are made of 409 stainless, which does rust fairly quickly. Highly recommend a coating before they go in. Also, the MF engine flange is thicker than OEM by at least 1/16th which creates a problem when installing. As terrible as the build quality is, they perform well and give a little extra sound.

Good replacement
This was a great bolt up replacement for my truck. Made my life much easier than fitting a universal cat. Definitely recommend.
