    Construction. This MBRP cat-back exhaust system is made from heavy duty, 100 percent aluminized steel and offers exceptional value and high quality. Installing this system can result in an increase of up to 18 horsepower and 28 ft/lbs of torque which increase your rig's pulling power and throttle response. From the fully mandrel bent tubing, to the spiral louvered high flow muffler, and the minimal bend degree angles, this system gets the most out of your Jeep's engine. It's easy to install, thanks to the bolt-on, no drilling or welding design, and it fits perfectly right out of the box.

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

      MUCH BETTER!

      I had previously had a flow master exhaust installed on my 2005 TJ for about 6 years until it rusted out and the welds snapped. I ordered this exhaust, 1-day shipped it, and had it installed that next day. It is so much better! My flow master was pretty obnoxious (as in I wake up the neighbors at 3 am when I go to work). The MBRP exhaust has that deep, throaty sound when in idle and with light acceleration and gets quite a bit louder/a bit more high pitched when you hammer down. Of course it’s not going to make my straight 6 sound like a big block but it gives it a nice sound versus the stock, whisper quiet exhaust. She seems to have a bit more get-up-and-go as well. Well worth the money! It doesn’t come with all new mounting brackets though which I needed.

      Replacement catback

      I was looking for a replacement for my rotted out stock exhaust. Found this one at a reasonable price. Solid Cat back, a bit more throaty than stock and makes the Jeep sound great!

      Nice sound

      The install was trouble free and the sound is a great improvement. The only thing I don’t like is that the chrome extension rest on the bottom of the rear bumper so I can’t use it until I get the pipe bent so it won’t melt extension on my bumper. With that being said good price and good sound. Well worth the money.

      Louder than I thought it would be.

      Great product. Everything was included, very high quality material. My bolts were a little stubborn, but got my stock off pretty easily. I wished I would not have taken off the skid plate. I did not realize the entire drivetrain is supported by the skid plate. Getting it back on was tough! After got it all installed and tightened, started up the Jeep and was very surprised by the sound. It had a deep tone and pretty loud inside. I love the sound of it, especially accelerating. Great price, great product, highly recommended.

      Great sounding exhaust

      Package came complete with all hardware, quality as expected. I installed it within 45 minutes, although I had a lift and power tools. It gives great exhaust note as well atleast 5 extra horses. Jeep drives great and I love the sound.

      Nice exhaust

      Very easy install , all the hangers (hardware) included. Wasn't impressed with the tone at first, their must be a break in period because after a couple of weeks the tone of the exhaust is great more than you would expect for a straight six cylinder very pleased. the gauge of pipe looks like it will last for years. install 2004 jeep LJ

      MBRP exhaust

      I purchased the exhaust exclusively to fit with my long arm suspension, since my long brackets rub on the OEM exhaust. I’m generally not a big fan of exhaust noise, but this exhaust actually sounds decent.
