    Why Pick MBRP for Your Wrangler?Wrangler owners expect a lot from their ride. Yet many exhaust manufacturer's figure they can simply pack the same generic muffler into their Jeep kits that they put on a Civic. At MBRP we designed our Jeep JK/TJ muffler to match the very real demands off-roaders have for their rigs. After many dyno runs with various muffler designs, combined with real world testing, we were able to pull 9 RWHP and 15ft/lbs out of the 3.8L V6. The unique chambered design of the muffler provides a pleasingly rich rumble at idle that builds to a civilized growl at driving speeds and a throaty roar when you push the throttle down. Unlike fiber packed straight through mufflers our chambered design can handle getting wet. Here at MBRP, we put a lot of thought into the exhaust system. The muffler remains to the rear to avoid having to reposition the evaporation canister. We tucked the muffler up as high as possible in order to provide maximum clearance while keeping it in the factory location. The heavy 16 gauge steel construction is tough enough to stand up to anything that the road, or off road, can dish out. The mirror polished T304 stainless steel tip can be easily removed for off road adventures and replaced for driving around town.

    The Best Systems Start With the Best MaterialsInstaller Series from MBRP brings you the best of both worlds. Designed and constructed to the exact same specifications as MBRP's Pro Series you can expect the same improvements in torque and horsepower and the same awesome sound as our top of the line products. The difference is the heavy duty aluminized steel construction. You save money without compromising on performance. MBRP Installer Series truly is superior to other aluminized exhaust products on the market. Heavy sixteen gauge steel is one reason. Another is that our systems have a thick protective coating of aluminum silica on the seams - an area that is often left exposed to rust. We are so certain of our Installer Series products that we back them with an industry leading 3 Year Warranty.

    Built to PerformYou made an investment in your Jeep and would never consider less than the finest aftermarket parts for it. Your MBRP performance exhaust is designed to make sure that is what you get. Aside from a stylish classic look, you can count on your MBRP cat back system to give your Jeep a rich, mellow sound. And thanks to the fully mandrel bent pipes, MBRP performance muffler and minimal bend degree angle design you can count on squeezing every ounce of torque and horsepower your engine has to offer.

    The Premium DifferenceIn an industry with its share of "commodity" exhaust products MBRP stands apart as a manufacturer of truly quality performance exhaust systems. You can see that in the way your system is packaged, the thought that goes into the design of every component, the consistent quality of the overall product and of course, the sound. The premium difference does not end there. Through our in house customer service team as well as the professionals who distribute and install our products you can count on your MBRP experience to be an enjoyable one.

    Easy InstallationMBRP systems are as much fun to install as to drive with on your Jeep. Bolt-on, no weld design makes installing this on your Jeep without hassle - an easy no hassle one to two hour project. Everything is direct fit to the OEM hangers and you get all the clamps and parts you will need, all in one box.

    Sound & StylePerformance is one thing but at MBRP we believe that appearance and sound is just as important. Every MBRP performance exhaust system has been specifically tuned to get the optimal sound from your vehicle. With our MBRP brand etched on the tips and our unmistakable styling, there's no question that you have the hottest exhaust on the road - MBRP.

      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.

      MBRP

      Fit perfect no issues installing pretty self explanatory, hardest part of install is just getting the old one out, just cut it out. I didn’t put the tip on just because of where it comes out, it will probably get trashed from slinging rocks out of my tires, but it looks great even without the tip! Took about 2 hours just because of the old one.

      The installation takes more time than you think because you need to drop the skid plate under the transmission to get to the bolts, other than that pretty straight forward. The sound is excellent, not to load and the tone great!

      Misleading Product

      I can only review the delivered product at this time. I just opened the package to find only the tail pipe painted back. That may not change the overall quality but it was advertised as all black.

      heavy duty, great sound, direct fit.

      Arrived quickly, all in one box. Easy installation after I removed the transmission skid plate which provided access to the existing bolts. Reused existing rubber hanger (one was perfect the other was worn but more than good enough to be reused. Hardware appeared to top quality and fit perfectly.

      Shop install for $65. They opted to cut the old exhaust out behind the cat flange and weld the new one in. Overall, sounds great for the price.
