    Will this fit my 1997 Jeep Wrangler sport with a 4.0 engine ? The video doesn’t mention 4.0 just 2.5

    DiegoR

    • No, this Flowmaster Direct-Fit Catalytic Converter is just for the 97-98 Jeep Wrangler TJ models with a 2.5L engine. Magnaflow does offer an option for the 4.0 which can be found here: https://www.extremeterrain.com/magnaflow-catalytic-converter-tj-23227.html.

    A reviewer said the hangar to attach the cat to the trans mount isn't included...photos show it attached. Which is correct?

    KevinU

    • Thank you for your question! The Flowmaster Direct-Fit Catalytic Converter is designed to come with a hanger on the catalytic converter.

    will this catalytic converter when installed to a stock 1998 jeep wrangler tj pass smog?

    Ollie

    • The Flowmaster Direct-Fit Catalytic Converter is (Non CARB compliant), so it may not pass your state SMOG test.

    Does this come with the midpipe that attached to the manifold.. I have tried to cross reference this part eleseware and it only comes up for Cherokee applications.. will this fit my 99 wrangler tj sport 4.0 inline 6

    BryanS

    • Thank you for your question! This will fit the 99 4.0L TJ, but this is a direct catalytic converter replacement and does not come with the mid-pipe.

    Do I need to purchase an o2 sensor with this product?

    MistiH

    • Hi! You do not need an O2 sensor when purchasing the Flowmaster Direct-Fit Catalytic Converter. You would reuse your stock O2 sensor.

    do you know why this is only for the 97-98 model year? the 97-2000 model year 2.5L have the same part number on the individual parts. is there a similar product for the 99 tj with a 2.5L?

    ErikD

    • The Flowmaster Direct-Fit Catalytic Converter is not designed for the 1999+ Wranglers. Since this is CARB compliant, it may be related to the CARB approval, or there may be a minor design difference Flowmaster made that does not allow fitment on 1999 and newer Wranglers. This has not been tested on a 1999+ by ExtremeTerrain.

      Review from Flowmaster Direct-Fit Catalytic Converter (93-95 Wrangler YJ w/ 2.5L or 4.0L)

      Perfect fit

      Old cat and muffler were shot so I decided to replace the whole exhaust with the flowmaster products and they all fit together like a glove. The pipe going into the muffler was a bit long and required some cutting but nothing major. Not sure how easy installation would be if you're just replacing the cat, but cutting the old exhaust out and sliding a whole new one in was a breeze. Overall a very simple upgrade that makes the world of a difference.

      Worked like a charm!!

      It bolted up with no problems whatsoever. The catalytic converter has a hole in it if you need the sensor, all you need to do is unscrew the plug. If you don’t the sensor its plugged. Very pleased with the catalytic converter would get it again.

      Feeling the Flow

      The Flowmaster CAT with mid-pipe was a great addition to my recently installed brand new exhaust system for my 95 Jeep Wrangler YJ. The CAT has fantastic flow and feel, and the overall performance and power is much improved over the stock system. The shop installer stated it fit like a glove when they connected it to the Flowmaster II Cat Back Exhaust kit! I would highly recommend to all YJ owners looking for an affordable solid mod upgrade or replacement of your stock system.

      Review from Flowmaster Direct-Fit Catalytic Converter (03-06 4.0L Wrangler TJ)

      Good replacement and upgrade

      I am fixing up a 2006 LJ and the stock exhaust is one piece from header all the way back to muffler. The rear cat is part of that long pipe. This part is a great replacement, especially if you have one piece stock. Now you can get in and work on the transfer case or replace the muffler, without having to go all the way up to the header. Also, this is slightly longer than some other cat replacements, so that helps with the amount you get to cut off. Measure first, and leave yourself enough to possibly trim again. I cut too close and had to run to auto parts store for a 2 inch filler piece. It looks nice once you get it on there and greatly simplifies a new muffler or just working under the skid plate area. I replaced the muffler (after cutting that off at the joint as well) so I am not sure how the sound is changed just by this. Overall it does seem to run smoother now.

      Not what I would expect

      Opened up when it arrived all looked good until I went to put it together. The cat pipe and the exhaust pipe would not go together. I had to take it to a exhaust shop and have the bell on the cat pipe enlarged to fit the exhaust pipe. Not what I'd expect from flowmaster. So to sum it up what should have been a breeze to assemble in my book was a genuine paint in the but.

      Not a day job for ALL setups.

      Be prepared that there will, as with all Jeeps, be some hiccups. Once i stopped cursing at the previous owners botch job, the parts all assembled with relative ease. And, i do love most Flowmaster products for the ease of install. This is one exception, being a heavy duty part for a lifetime of use.... the flange clamp to attach the down pipe to the exhaust manifold is THICK by comparison to the stock. The piping itself is also thicker. Thus the quandary, the stock manifold bolts are 1/2" too short at least. Be prepared for it.

      Bad Fit

      I had this part put on at a muffler shop. The tech told me that the part did not fit right. The piece which had the catalytic converter on it was to short. The piece which came off the exhaust manifold needed to be modified some.

      Nice replacement part

      I would give this part a higher rating but the down pipe flange s to think and will not fit with the bolt already in the exhaust manifold. It does come with longer bolts but they are impossible to replace without removing the manifold from the vehicle.

      Nice cat, quality product, but not all there. The original cat has a mounting arm/hanger on it. The hanger acts as a support for the exhaust system. I had to cut the old one off and weld it on to the new one.....Giant pain in the $#

      The Flowmaster Cat. Converter was a great buy at Extreme terrain. Had a quick and easy install and sounds great. You'll love it, combined with a flowmaster muffler my 4 cylinder sound's like a 6 cylinder. Performance was much improved over my last, and cheaper also.

      worked as adverttised.

      I bought this converter to replace a Magnaflow unit that fell apart. The install was quick and simple. the only reason I spent an afternoon on it was that I took the time to clean and paint the frame components while I was under there.
