      Review & Installation Video

      Hey guys, what's up? I'm Ryan from ExtremeTerrain. And today, I'm here with the MBRP Installer Series cat-back exhaust for your 2000 to 2006 TJ. Now, this system is going to be for anyone that's looking for an easy upgrade that's a direct bolt-on for a reasonable price. Whether you're looking for some power and sound improvements, or you're just trying to ditch that old exhaust, you really can't go wrong with this system. Coming in at just over $200, this is currently the most affordable system on our site. As far as muffler design goes, MBRP actually mirrored this off of their Pro Series, so you're going to get the power and sound of a much higher dollar system at a much lower cost. As far as loudness goes on a scale of one to five, I'm going to rate this at about a three since it's going to give you a more aggressive and louder tone over your stock exhaust. This is going to come as a complete kit. Whether you have a four or six cylinder, this will work and it uses all the OEM hangers. This is made of 16-gauge heavy duty steel, and it has an aluminized coating to resist rust. As far as install goes, I'm going to give this a two out of three wrenches since you can use simple hand tools and install this in a few hours. With that being said, let's jump in to the install. So, first up to this install, we're going to unbolt the muffler from the catalytic converter. Now, the flange at the front of it has two bolts, we're going to use a 15-millimeter socket for that. To make it a little easier, if you can remove your skid plate, you'll have better access to get to that. However, our bolts are a little stuck so we're going to just use a long extension and get those out. So, afteryou get those two front bolts out, we're going to need to cut the exhaust so we can fit it out and around the rear axle housing. So, we're going to cut it right here at the back of the muffler where this tailpipe goes over the axle. So, you're gonna want to wear safety gloves and safety glasses. After it's cut, you can go ahead and pull muffler out and then we'll remove the rest of the tail section. So, to remove the tail section, there's two hangers. One is going to be at the front of the axle, the other one's going to be right here. I actually have an exhaust hanger removal tool but you can use a pry bar or really anything to get those off. You want to spray it with some WD-40, that's actually going to make them a little more slippery and easy to come off. So, we're going to remove this first one back here first. And now, we're going to do the other one. This point, you're going to want to grab onto it so it doesn't fall out of the Jeep. So now that we have our factory exhaust removed from our Jeep and our new MBRP Installers Series laying next to it, I wanted to take a minute just to do a side by side comparison. Now, the first thing you're going to notice is the new muffler is smaller. Not only is the muffler smaller, but it's actually going to mount up higher in the vehicle, but it's going to maintain that factory location. The next thing you're going to notice is the inlet and the outlet are larger tubing. This is also a straight through design which is going to give you better flow and more sound. Next, you are going to notice that this piping is a lot straighter and is high clearance as well, so it's going to avoid all the springs, axle and everything back there. So, the last thing to point out is the tip. Now, the tip is made of 304 stainless, so it's not going to rust and it also looks much better than just a pipe sticking out of the back. This is also removable, so if you are going to hit the trails you don't want to scratch it up, you can take it off easily. Now, that piece is stainless steel. The rest of the exhaust is steel, but it's coated in aluminized coating. Now, this is much cheaper than a stainless setup but it's also going to last a lot longer than steel. With that being said, let's show you how this gets installed. So now, that we're back under the jeep, we're ready to start assembling our exhaust. First, we're going to start with our muffler. We're going to go ahead and slide the one end up over the skid plate and then we're going to hook on this back hanger while we get the front bolts in. So next, we're going to use our provided hardware, we're going to put a washer on the bolt, and then we have a washer, a lock washer and a nut. So now that we have our muffler installed, we're going to install our tail section. This is just going to slide over that existing pipe and then we're going to put this hanger on. Now that we have this pipe connected to the muffler, we can go ahead and install this hanger and then we can install our tip. Next, we're going to install our provided clamp and then we'll tighten that up using a nine-sixteenths. So, after you have your clamp tight, we're going to go ahead and move up to the front of the muffler and then tighten up those bolts. We're going to use a nine-sixteenths wrench and a nineteen-sixteenths socket. So, after everything is tightened up, you're ready to install your tip. You're going to use a five-sixteenths Allen key to tighten it up. So, with everything adjusted properly and tightened up, that wraps up my review and install.

        What I wanted (if I have to run a muffler)

        The muffler on my jeep literally broke off. It looked like several people had tried different things to get my OEM muffler to stay put. When it finally broke it sounded like a screaming daemon, and it was beautiful! I would love to run it that loud all the time but it is not feasible. So I went with MBRP. I have a soft top, with a fully bed-lined interior and am still able to have a clear conversation at 55mph.

        Sounds Great!

        It was a little harder than I thought so I had a buddy help me because he had a lift. Then it was piece of cake! Looks good and gives my jeep a nice rumble. Nothing over the top, low growl. It's worth it...don't worry!

        Best Bang for the Buck

        Easy and Simple installation. Took me about 2hours alone with floor jack and stands. Only down fall play around with rear hanger due to hitting gas tank skid plate.

        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

        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.
