          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 Jeep 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.

          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.

        This company has always been the go-to site for good deals, good products, and service. I never have had problem with the products sold, even after several years of use. For example I have had the tire rack on my jeep from 2003 to now, I have brought a new jeep and the first thing I ordered was a new rack from them for my new jeep. Good product, good service, and the best prices. I use this company as a base line to compare other dealers with, and this company always wins out.
