      Sounds good, fits good

      Didn't take super long to install, I like how the pipe and cat are two separate pieces. It makes it much easier to deal with during install

      FlowMaster exhaust

      Very easy to install came with all the hardware you need except for the clamp from cat to muffler. Everything lined up perfectly. And the price was pretty good!! I would recomend this to anyone needing new manifold back to muffler!

      5 1993 Wrangler - Jim Installation Time: Full Day

      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.

      5 2001 Wrangler - Lester Installation Time: Less than 1 Hour

      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.
