    Review & Install Video

    The MBRP XP Series four-inch, single side exit exhaust will be for any 2015 or newer 3.5 EcoBoost owner who might be looking to pick up a deeper and louder exhaust note, yet not too overwhelming in sound. Now, obviously, there are a ton of options on the market for your 3.5 EcoBoost, and especially a couple of them from MBRP alone. This one is going to be a midlevel option in the MBRP trifecta of exhausts, all giving you the exact same sound with just different materials at a different price range. The install will get a very simple one out of three wrenches on our difficulty meter. Since this is an exhaust system, obviously, the first thing I want to touch on is, well, going to be the sound. Now, as you just heard from our sound clips, I'm going to give this a three out of five on our loudness meter. It is going to be deeper and throatier, and just a bit louder than your stock exhaust, and obviously just not the loudest. If you're looking for ear-ringing, ear-popping options, there are some five out of five loudness options out there. This is going to be a pretty quiet idle, nothing to crazy up front. You might not even notice it's aftermarket. Now, once you get it going at the RPM band on the highway, it'll definitely get up there in sound and even give you a little bit of drone. So keep that in mind going forward, as well. My personal opinion, it is a little bit better than the stock option and it can all obviously be attributed to this muffler right here. It's going to be a bullet-style muffler with a straight-through design inside, giving you that nice sound that gives you the three out of five on the meter. Now, everything else is going to be 409 stainless steel, a midlevel option, all going to have a four-inch tubing throughout, which is something a lot of guys strive for. To top it all off, you're getting a very attractive, polished finish with a five-inch monster coming out of the rear. This one does come in right around the $500 mark. The price tag is going to go right inside with the materials. Since it is a 409 stainless steel, it's a durable one. But obviously, not going to be as good as a 304 stainless steel. 304 stainless will go for $700, so just about $200 more. It all comes down to whether you're willing to pay that much more for the exact same sound, but just better materials. If you're looking for a pretty budget-friendly option with good materials, this is going to be the one for you. Shifting gears over to the install portion of the video, like I said in the very beginning, it's going to be extremely straightforward. Very simple hand tools required, a ratchet, a simple socket set, a jack and jack stand if you have one, or a lift if you have access to that as well, just to make your life a little bit easier. Overall, from start to finish, maybe an hour, two at the absolute maximum if you need some help there, and then of course a one out of three wrenches on our difficulty meter. From start to finish, it's really just a matter of unclamping your factory exhaust, getting rid of the flanges, pulling everything off of the hangers, and setting it aside. Overall, that's not really too hard to tackle. From there, you'll take the mid-pipe and the factory flanges, and attach them over to the MBRP one that's preassembled for you here. Bolt those down using the hardware provided for you in the kit, and work your way down, attaching everything into their proper hangers. You can use the factory ones at that. Bolt up the muffler, working your way down to the five-inch tip, which again is also just going to clamp right on. Overall, like I said, an hour or two at the max, one out of three on our difficulty meter. If you're the owner of a 2015 or newer 3.5 EcoBoost, you might be looking for a deeper, throatier, louder exhaust that isn't too overwhelming, while getting some longer-lasting material, while also not going too overwhelming in sound and as well, price. You might be looking at the MBRP XP Series four-inch single side exit design with a polished stainless steel tip, available right here at

            MBRP 4in XP series

            Excellent quality and sound it’s loud when you want it to be but quiet cruising down the highway with little to no cabin drone. The installation was very straight forward I had the old exhaust off and the new one on in less than an hour very happy with this product and would definitely recommend it!

            Great sound for little money

            After extensive searching for a cheap but worthy exhaust, I settled for the MBRP XP 4 inch. Not only is there a rebate of $50 but there is also a LIFETIME WARRANTY. The sound was a little loud at first considering the stock exhaust is very quiet. I was also hoping for a slightly mellower tone. The truck runs pretty quiet at highway speeds given the low RPM's on the 3.5 ecoboost. I had also installed a KandN intake on the truck as well to allow for the maximum airflow possible. You shouldn't strangle a duel-turbo setup. I have yet to buy a tuner given I don't want to void my warranty, but I can honestly say that the truck is very peppy and has a leopard like purr to it on the streets. I can say for the price this kit can't be beat. I did have to cut the extension pipe to 15" from 22" given that I have a supercrew cab and a 6.5 foot bed. Easy to assemble and no problems doing it myself. The stock exhaust was easy to remove given that I did this in my driveway. I suggest that if you are weak you my want to get an assistant or put it up on a rack. I highly recommend this product for ease of assembly, performance and price.
