    Review & Installation Video

    Review & Install Video

    Hey, everybody. I'm Alex with Today I'm bringing you my detailed review and breakdown of MBRP's Installer Series Four-inch Cat-Back Exhaust in the single side exit configuration, fitting all 2011 through 2014 3.5-liter Ecoboost equipped F-150s. Then I'm gonna walk you through the installation, which right off the bat, I will be giving a very easy one out of three wrenches on the difficulty meter, and about a two-hour job. However, I will mention that depending on your cab size that there might be the slightest amount of cutting and I will have more information for you on that later.So you just heard the sound and driving clips and you can be the judge what this sounds like, but having a 2014 Ecoboost that has a similar style exhaust system, I can definitely attest to the fact that this is a modest bump in terms of tonality. It's gonna throw some great noise, and we're gonna be giving this a three out of five on the wake the neighbors or the loud meter. Now the four-inch installer series from MBRP that I have here today should be a great option for any Ecoboost F-150 owner out there that's looking to get into a very affordable system, as well as picking up a modest bump in terms of sound and decibel level, be it in and out of the cabin. Now pricing aside, I'll say it right now, this is only gonna set you back 350 bucks. This should definitely appeal to any F-150 owner out there that's looking to, again, get into a very inexpensive and very quality built product, but something that's gonna give you that nice bump in terms of tonality, be it outside or inside the cabin, but, for something that's not gonna be killing your ears on long drives or making your significant other, friends, family, or kid hate driving around with you in your truck.So something I really like about this system in particular is the fact that this is gonna be a factory style exit or configuration, which, again, means that it's gonna shoot out right where your factory exhaust tip does. Depending on the style that you're after, MBRP's gonna have the entire spectrum covered here. It's gonna range from your factory exit, something that's gonna dump right behind your tire, to a dual to a split rear. Now going back to the sound here, what you heard early on, in my opinion, is definitely gonna be a little bit more on the milder side in comparison to, say, something like a Flowmaster cat-back or maybe even Ford Racings by Borla, which is gonna be a little bit more on the aggressive, a little bit more on the higher pitch side, and that's gonna be due to the muffler construction that they're using between systems. With this system here, this is gonna have a bullet style muffler. As you can see, there's really not gonna be that much packing inside. But, despite not having that material inside of the muffler itself, it's actually very manageable and livable. On cold start, you're gonna be getting a ton of feedback, lots of snap, crackle, and pops, but once it comes up to temperature and you're driving it around in the real world conditions, it's very manageable based on how far you're sticking your foot to the floor. When you're going wide open throttle, everybody around you is gonna know that the aftermarket exhaust is there, but as soon as you take your foot off of it, it's gonna be a very nice, modest rumble, not gonna get something that's going to make you hate driving your truck on a 10 or a 15-hour drive if you had to do so.But something I want to make sure you guys keep in the back of your heads is that their bullet style muffler is gonna be consistent throughout the entire line, but the main differences here between, say, the Installer series and an XP series is gonna be the use of aluminized steel as opposed to a 409 stainless. So if you're living in parts of the country, be it say you're on the coast or you're gonna be seeing winter weather more often than not, I might personally suggest getting into a 409 as it's gonna be that much more durable, but you should expect to be paying about $100 more.Now down to brass tacks, this is gonna be comprised of a four-inch diameter mandrel-bent aluminized steel construction. Again, that bullet style muffler right here is where you're gonna be picking up most, if not all, of that turbo noise and feedback, either going wide open throttle or coming off of diesel [SP], and that's all gonna exit through MBRP's five-inch polished chip, which, I know it may sound like it's on a little bit of the larger side, but on the table here and on the truck, it honestly looks right at home.Now I said it before, this thing is not gonna be doing too much to your wallet. You should expect to be spending 350 bucks, which, at the time of shooting this video, is gonna make this one of the most affordable cat-back systems out there for the Ecoboost. I do want to throw it out there again that you're gonna be getting aluminized steel here, in comparison to the XP's 409, a straight through muffler, which is gonna give you all that sound and tone, be it outside or inside the cabin, which is all again gonna exit through that five-inch polished tip.Now like I said initially, getting this under your truck is not gonna be a difficult feat. You should be looking and expecting a very easy one out of three wrenches on the difficulty meter and about two hours of work. However, I did mention that depending on your cab size, which could be the standard cab or the SuperCab with eight-foot bed, that you might need to do some cutting. Now looking ahead, if you are the standard cab owner or the SuperCab with the eight-foot bed owner, I'd make sure to have a Sawzall and a couple fresh blades handy. Aside from that, a full socket set, a couple jack stands, some WD-40, and a little bit of patience will get this on in no time. Now we're gonna begin by taking your factory system off. Well, that WD-40 is gonna come in handy. If you don't have that, some blaster will work just fine. You're gonna want to soak liberally all your hangers and insulators, as if you've never removed your factory exhaust, chances are it's gonna be pretty stubborn coming out. Now first up, you're gonna wanna loosen the flange right behind your Y-pipe and then loosen up the clamp that's gonna be located in front of the muffler. After that, you can remove your hangers from the rubber insulators and then remove the exhaust from your vehicle. Now getting your new system on, you're gonna start with your front pipe to the existing flange using the supplied hardware, and then attach the muffler, along with inserting the muffler hanger into the existing rubber insulator. Now once that's completed, slide the three-inch clamp over the extension or front pipe. Once you're done there, loosely install the over axle pipe that's gonna connect it to the muffler outlet using a three-inch clamp. Now once that's completed, your damned and you're done and it's merely gonna be putting your exhaust tip on the existing pipe, locking it down. And then I would just suggest running over all of your connections, making sure everything is tight, and then I would definitely make sure that the exhaust is not gonna be coming into contact with anything like, say, a brake or a fuel line or your spare tire, just to be on the safe side.All right, guys, so just to wrap things up here, some final thoughts. If you're the F-150 owner that's looking to get into one of the most affordable cat-backs at time of shooting this video, something that's not gonna hurt your wallet, that's gonna wake up your truck moderately and bring a smile to your face whenever you're stomping on the gas, I would definitely suggest checking this out for your rig. I'm Alex, and that's my review for MBRP's four-inch Installer Series Cat-Back in the single side exit configuration, fitting all 2011 through 2014 3.5-liter equipped Ecoboost F-150s, which can be found right here at

        How loud has this turned out to be for everyone? Based on the video's it doesn't sound too terribly loud (I mean, it IS an aftermarket exhaust). I just don't want to bother neighbors and/or cops and such.

        • I wouldn't say this is the loudest exhaust that we offer, but it's certainly of the more aggressive we have relative to the rest of our selection.

            Great tone, Performance boost

            After installing the MBRP there was a definite tone increase (really not that loud, just a lot lower and sounding 100 better!) Time to install was a bit longer than expected, there is some trimming on the extension tube (pretty easy, but just a heads up) and uninstalling the factory exhaust was pretty straight forward as well.

            Love it

            Installed this exhaust with catless downpipes, stage2 cold air and cs2 tuner and 33" tires. Easily smoked the tires down to nothing. Bought a new set and hooked up my 28' camper and drove 1000km the following day. Crossing the Rocky mountains in the process. Love the sound rolling down the highway and even more through the mountains. Had plenty of addition power to roll up and down the mountain side with ease. Only issue I had was with the truck running a bit warm, but It was 30 degrees celcius as I was driving in the mountains so that's not really a surprise. Sound of the turbos whistling is a real treat

            Turbo whistle

            Definitely worth the money! Aggressive idle with a great note at higher rpms. Turbos are a lot more noticeable now too.

            Sound inside truck

            The exhaust was very easy to install being that I've never installed one before. Wishing I wasn't so cheap and bought the stainless.(Don't be cheap) The exhaust lined up fine, had to tweet a few things to fit the way I wanted. Let's move on to the sound. Hmm, the sound of the truck at idle sounded great as on the internet video. As you get on the gas it sounded fine outside the truck but inside the truck is another story. Sounds like a Honda Civic with one of them coffee can exhaust. Hoping with some sound deadening stuff will fix that.
