      Video Review & Installation

      Justin: If you're looking for one of the most affordable cat-backs on the site for your 2018 in newer GT, then the Installer Series from MBRP might just be the system for you. Now the street variation that we do have here will deliver that classic thumping muscle car tone. Thanks to the combination of the included H pipe right here, and, of course, the street series mufflers while at the same time we utilize that aluminum steel keeping the price point in check right around 600 bucks. So MBRP is all about options. They've got many different systems featuring many different materials for many different budgets. Now the Installer Series that we have here is essentially going to be the company's entry-level offering for that new GT, thanks largely to the material used. Again, aluminum steel. Now you can spend a little bit more and get into an XP or Pro Series system, both of which will utilize a full stainless steel build. But if you're looking to keep things as budget-friendly as possible, well then you're in the right place here with the Installer Series. But before we go any further with the build and specs, let's talk about sound. And honestly, this might just be one of the best bang for your buck or bark for your buck systems in the category. Powerful but not over the top volume with a nice deep tone which altogether is good enough for a very healthy three out of five on my patented one to five for one to wake-the-neighbor scale. Now there is a bit of volume inside the car when cruising. But overall, it's not oppressive and certainly shouldn't be a deterrent, especially at this price point. Now if you would like to go a little bit louder but stay at this price point, then the race version of the Installer Series might be a little bit more your speed instead. And feel free to check out that system along with the corresponding sound clips here on the site as well. But now, let's get into how the streets system delivers that deeper tone overall. And again, it's going to be the combination of the included H pipe shown right here working with the street series cans from MBRP. Now if you've been looking into the category for cat-backs for the new GT, you've probably noticed a lot of X pipe options on the site. They're going to far outnumber your H pipe options, and by a pretty wide margin. In fact, at the time of this video, the only other system that you can grab with an H pipe for the mid pipe here will be from AWE. But you're going to be spending nearly double the price tag of the Installer system that we have here. Aside from that H pipe, you are getting 3-inch Mandrell bent tubing essentially from tip to tip. Here, again, your material is aluminum steel, which isn't the most durable metal out there in regards to long-term corrosion resistance but will work just fine as long as your car doesn't see a ton of salt during those winter months. You're also getting a small amount of stainless steel here with the MBRP, and that would be the quad 4-inch double-walled tips that are etched with the MBRP logo. Now because the aluminum steel is a little bit more susceptible to the surface corrosion compared to full stainless, for instance, MBRP will only give you a three-year warranty with the Installer Series compared to the full lifetime warranty of an XP or Pro Series system from MBRP as well. As far as your installation, well, it shouldn't test it too much here guys because, again, everything is going to bolt into place without any cutting or permanent modification. So I'll call it one out of three wrenches on the difficulty meter, and maybe an hour or two of your time from start to finish. Let me give you a better idea of how this job will go. Here is a detailed walkthrough. Man: Now to begin the disassembly of our exhaust, we're going to use a 15-millimeter socket on our impact gun and disconnect the clamps at the far end of the exhaust that connects it to the catalytic converter pipes. Now we're just going to loosen up these four bolts and the clamps here. This way our entire exhaust will slide right out. Next, using a 13-millimeter socket on our ratchet, we're going to go ahead and disconnect our hangers from the rear of our vehicle. This way we can slide our entire exhausts out as one unit. But we're going to do it with the help of a friend because we actually have our vehicle up on a lift not down on the ground with Jack Sands where it would be a little bit easier to do it by yourself. Okay, using our 13-millimeter, we're going to go ahead and take out these two bolts here to disconnect our hangers. Next, we're going to move up above the mufflers to get the two hangers that are up there. I'll show you those in a minute. Okay. Moving back here to the rear, we have two bolts that have to come out of each hanger. Now we have one going up from the bottom and one coming in from the side. We'll still utilize a 13-millimeter socket to remove these, so we're going to go ahead and get these disconnected. Now we'll get the help of our friend to side our whole exhausts out. Now there's one of these hangers on each side. All right, now we're ready to pull our exhaust out. We're going to get the help of our other installer, Nick to give me a hand. And we're just going to unhook these from the cross member and slide the whole exhaust out as one piece. There we go. The first piece of our new exhaust assembly is an H pipe here. Now we're just going to go ahead and slide this into our factory clamps are still on the back of our header pipes. We'll rest it on top of my screw jack here just to give me as a third hand to hold this into place while I get the rest of the pipes installed. Now one thing we will be using from our factory exhaust is our rubber hangers. Now I remove these from the midsection of our factory exhaust, and I'm just going to go ahead and hang these backup here on our cross member for the time being. Because the next couple pipes that we put in, we're going to hang them from those to keep them nice and steady. All right. Next, we're going to go ahead and install our first under axal pipe. Now this one's for the driver side, and I took the hangers back off our cross member and just slip them on over our new hangers that are on our exhaust. Now we're just going to go ahead and slide this over the pipe, making sure that we did have our clamp installed on the pipe organ. Now you don't want to tighten these just yet because we're going to need to leave them loose for adjustments. Let's go ahead and poke our hanger back over and just let that hang for now. Now let's go ahead and get our passenger side one on. It's the exact same step. Once again, make sure you have your clamp on there. Slide pipe A into pipe B. Hook up clamp C, and you're good to go. Next, we're going to install our new muffler for our cat-back exhaust. To do this, we're going to use our original stock hangar that we took them our factory exhaust plus another new clamp. Now I'll just go ahead, slide this over our new pipe, and lock in our original hangar once again leaving everything loose until we're completely done. Now I'm going to go ahead and install our bolts into our hangar just to get it locked into position. We're going to leave all the clamps loose until we're completely done. Now I'll just go ahead and repeat all this for the other side. Now before we get our tips installed, I'll go ahead and go through and line everything up to make sure everything is nice and square and even. And I will start tightening our clamps up to get this all locked into place. Then we'll go ahead and get our tips on, and we'll be finished. Before we forget, let's go ahead and install our 13-millimeter bolts back into our cross member hangers. This way, our exhaust will stay nice and in place. And we just don't wanna forget these because it will rattle around if we do. Next, I'm going to go ahead and get our tips installed. Now you want to go ahead and install these one at a time. This way you can get to the mounting hardware, and so you can line them up nice and properly. Now what I'm going to do is go ahead and slide them both on, line them up the way that I want them. So I'm going to slide the first one off while I go ahead and tighten up my first one. Slide our other tip on. Go ahead and line that one up. Next, you're going to just go ahead and repeat this for the other side making sure that they're nice and straight and they're all even, and you'll be ready to go with your new MBRP exhaust. Now just go back over and double check everything and make sure it's all nice and tight. And that's all it takes to install the new MBRP Installer Series cat-back exhaust on your 2018 Mustang GT.
