    Improved Performance. Providing more torque and horsepower for moving your 2000-2006 TJ Wrangler over the trail or out of a sticky situations, the MBRP Black Series Cat-Back Exhaust is an elegantly straight forward single side exit exhaust system. Growling fiercely during acceleration, it settles into a mellow, rich rumble when you're cruising or driving at a fairly steady speed. Besides a welcome boost in horsepower and torque, the MBRP Black Series often produces +1-2 mpg additional fuel economy, depending on your Wrangler's exact configuration. The large black tip looks strong but stealthy, giving a unique look to your Jeep, too.

    Bolt-On, Tough. The MBRP Black Series Cat-Back Exhaust is made with a bolt-on setup that doesn't need drilling or modification to install, and comes with all necessary hardware. The system features aluminized steel construction with 2.5-inch tubing and a 3.5-inch tip, all black coated for appearance and additional corrosion proofing. All parts are laser-cut for an easy, exact fit, and the Cat-Back comes with a 3 year system warranty and a 1 year finish warranty (limited).

    Application. The MBRP Black Series Cat-Back Exhaust is designed to fit 2000-2006 Jeep Wrangler TJ models, excluding Unlimited.

            Great sound and fit

            Everything bolts straight up to factory cat easy install just have to wiggle a bit and if you have a lift you need to stretch the rubber hangers a bit to get them in but they still work louder tone than factory

            4 2005 Wrangler Unlimited - JasonH Installation Time: Afternoon

            Install easy, more interior volume than expected

            I installed this in about 3 hours including some work to cut the old exhaust off. The rear most hanger attaches in the inside of the frame rail and on my LJ it was rubbing the plastic of the gas tank. This may be due to my tummy tuck. I reused the factory hanger location by cutting the hanger off the old muffler and reusing it. Overall the sound outside the Jeep is pretty good, deeper and louder than stock. A little louder than I was expecting. I'm finding however that the extra noise in the cabin is louder than I wanted on a daily driver. The quality and fit of the product were very good and the price was right. If not for the additional interior noise I would be completely satisfied.

            5 2003 Wrangler - DrSwagPHD Installation Time: Full Day

            Great sound and fit

            This MBRP exhaust mounted right into my 03 TJ in all of about 15 minutes after getting all the stock components off. The fit, finish, and sound are all great given the low price tag. The exhaust note is just a little louder and deeper than stock. 10/10 recommend Luckily I was already diving into some other modifications, because getting the stock exhaust off was not anywhere near as easy as it was depicted in the install video. The stock muffler was rusted on so I had to drop the skidplate, which involved grinding off a bolt due to a stripped nutsert. Then I had to cut the bolts holding the muffler on because they were so rusted together. So if your Jeep has a decent amount of rust, don't expect a quick install.

            Sounds Great

            Great sounding exhaust. Makes to 4.0 sound tough! Installation was a little tricky. Depending on rust, you may have to drop the skid plate to make this happen, and that is a huge pain - watch some videos for proper technique. Once installed - very pleased.

            Fits perfect.

            2002 Wrangler. FYI. The bolts connecting to catalytic converters to muffler is nearly impossible to remove without dropping the skid plate. The video makes it look easy to remove the 2 bolts with a socket extension, but it is not easy. Careful when dropping the skid plate because then drive shaft will also drop. I used jacks to hold the driveshaft up when dropping the skid plate. Then, no problem at all with the install.

            Good replacement

            Gave it a deeper sound but not too loud. Definitely happy for the price. Was hoping for how my CJ used to sound. the install went well. Probably 45 minutes. Remember not to tighten muffler until you have everything lined up. I had to lower one side of my skid plate with trans supported by jack.

            5 1998 Wrangler - JKFitz Installation Time: Less than 1 Hour


            After a knock developed in the exhaust system I decided to replace both the muffler and catalytic converter. Glad I did as after taking them apart and cutting them open I found 6 pieces of catalyst floating around in both the converter section and the the muffler. That explained the knocking and also the intermittant loss of power as the chunks would sometimes get into the pipes in the muffler chamber. After replacing both sections my old TJ runs and sounds like new! My top end is back. It has never run better! The exhaust tip also looks great and changes the tone to a slightly lower note. Great sound but still quiet. I could not be happier! Side Note: Extreme Terrain has been great to deal with, I have ordered several items for my jeep and their customer support is excellent!
