      Review from MBRP Installer Series Cat-Back Exhaust (00-06 Wrangler TJ, Excluding Unlimited)

      Perfect Fit with Throaty Sound

      Hangers lined up perfectly, as did all the clamps. I sprayed all but the tip with high heat exhaust paint before installing. Exhaust was packaged well and the tip was boxed separately to avoid damage. Definitely louder than stock, but has a nice throaty sound.

      MBRP cat-back exhaust

      Loving this exhaust. Gives a nice melllow tone for a 6 cylinder. I have seen a small increase in my gas mileage. A cold air intake and a cat-back exhaust is definitely a must have for a TJ.

      good value

      I installed this on my 2004 TJ 4.0L. Took some time to get everything lined up, but eventually got it all installed. Sounds good with a deep rumble to it, however, not loud and obnoxious. Word of warning....if you have stock bumpers and the exhaust tip doesn't clear the bumper, your plastic bumper ends will melt. I really don't care because I am planning to replace the stock bumper eventually anyway. This project took me a bit longer to complete because I had issues getting the old muffler off (ended up cutting it off). The install of the new exhaust took less than half as long as the removal of the old exhaust, but does take some time to position and bolt up. Bottom line is that it sounds good and the price is right.

      Fantastic fit and finish

      Had all the skidplate bolts not been rusted to the body of my daughters TJ this product would have been a snap to install. Great exhaust note though perhaps a little loud for some.

      This is a great exhaust system for the money. Removing the old exhaust and installing the new one took about an hour. Greatly fit and great sound. I couldn’t be happier!!

      Budget friendly exhaust

      I bought this system because of the price point and decent reviews from others. It was easy to install and fills the intended purpose of replacement cat back system well. There are better types of pipe clamps on the market but again this is a budget system so you can deal with that. I installed this on a 97 TJ with a 2.5L 4cyl. It is considerably louder than stock but that's not a bad thing.

      Review from MBRP Installer Series Cat-Back Exhaust (00-06 Wrangler TJ, Excluding Unlimited)

      Good product

      Overall the project took me 2 hours but also including some much needed cleaning on areas underneath while the stock equipment was removed. Do yourself a favor and the night before hit the bolts on the old exhaust system with some PB blaster or something to loosen up the rust and dirt. I recommend doing this on a lift to save your old exhaust and prevent cutting etc. Removing the new exhaust was simple and I believe it sounds better and throatier while not obnoxious. Performance is also slightly improved with responsiveness and slight gain in torque, it is noticeable. Combined with a cold air intake will also yield great results. Definitely a sound upgrade that you won’t regret and it also looks and sounds good while maintaining the appearance and sound of a Jeep.

      Perfect Tone

      Despite being bolt on, I needed to have a muffler shop install it because of a previous owners poor modification. Also the muffler itself was not black as advertised but I expected that from previous reviews so not a real big deal. I still give it 5 stars for sound, performance and overall look. Nice upgrade!

      Awesome!

      Very high quality exhaust with a great sound. Everything fit perfect and looks to be of superior quality. I was a little concerned when the box showed up torn open, but everything was in there. I upgraded to walker band clamps because I like them better than the u clamps that came with the kit. Overall I'm extremely happy with the kit and sound. Big improvement over stock, but not too loud and very minimal droan that I don't even notice after a few days.
