    Review & Install Video

    Hey, guys, Justin with, here with my detailed review of the MBRP Race Catback Exhaust System with Y-Pipe, fitting your 2015 and up Fastback EcoBoost. Now, the Race Catback from MBRP is one of the most popular options for your EcoBoost here on the site and for a few different reasons. For starters, it's currently one of the most affordable options for your ride; it's going to offer full three-inch diameter piping from tip to tip; and finally it sounds really good despite not costing you an arm and a leg. Now, one thing I personally really enjoy about MBRP is the amount of options they give you in choosing the right system for your ride. For instance, we're looking at the full stainless steel version of the Race Catback here. It's going to cost you a little bit more but not by much. It's going to offer a full lifetime warranty from MBRP, largely in part to the full 409 grade stainless steel construction throughout that's going to do a good job of reducing any surface corrosion.In addition to that, MBRP does throw two aluminized steel versions of this exhaust at you. One's going to come with black mufflers, black tips, and black piping, and the other's going to be left in that raw aluminized steel silver color. Now, both of those options only carry a three-year warranty, but they're going to be the most affordable. Now, I did want to spend a little bit of time on tone, because obviously, this is an exhaust after all, and that's a big deciding factor. But a big question I get a lot is: How do I make my four-cylinder EcoBoost Mustang sound good? And honestly, guys, a lot of that is going to depend on what your definition of good is, but what I can tell you is that the MBRP Race is going to deliver a very enjoyable tone, deep, low tone here with practically zero rasp, minimal drone on the highway, definitely not a deal breaker, but you can hear it slightly, and overall, a very, very solid three out of five on my one to five or one to wake the neighbors scale.Again, you can hear this thing, but it's not going to be totally crazy loud. However, add in your favorite off-road or catless downpipe, and that number would go up considerably. As for the construction, guys, well, again, I did touch on this earlier, but you do have the full stainless option available to your here. That's the one I have on the table with me, 409 grade stainless. It's going to offer a little better durability over time. It's going to cost you a little bit more, but you do get that full lifetime warranty with the system.Those two aluminized steel versions, again, great systems. They're going to be a little bit more affordable, but they're only going to carry that three-year warranty, maybe not be as durable when it comes to reducing surface corrosion, but overall, still a great system. You are getting three-inch mandrel-bent tubing from tip to tip with this system, solid welds despite the price, and you are getting the race mufflers, along with the very large four-and-a-half-inch slash-cut tips, etched with the MBRP logo. You are going to be looking at a simple one out of three wrench difficulty here, guys, when it comes to the install. No cutting or permanent modification needed whatsoever. This is a direct bolt-on part that should make the install a little bit more easy on you. Now, as for tools, well, simple socket set here. You're going to need a large Allen key to tighten up these tips here, but overall, figure about an hour or two in the garage or driveway before you're making some noise. All right, guys, to wrap up the MBRP Race Catback, I do really enjoy this system for the simple fact that it sounds good; you have some options when it comes to the materials; and it's not going to cost you and arm and a leg to put it on your car. So be sure to check out more from MBRP for your EcoBoost Mustang here at

        5 Top Rated Questions

        is it fix with convertible?

        • Unfortunately, the MBRP XP Series Cat-Back Exhaust is only designed for the Fastback. It will require some modifications to have a proper install.

        Helpful (12)

        Its this exhaust system legal in California?

        • Yes. The only thing you have to worry about, in terms of exhaust, while living in California are the catalytic converters and the headers. Otherwise you'll be fine!

        Does this work with the stock downpipe? If it's a 3' tube, how would it fit the 2.25'' downpipe?

        • The MBRP Race Cat-Back Exhaust w/ Y-Pipe has a step down adapter that allows it to bolt onto the factory downpipe with no issues.

        What is the loudest? The xp series, black series, or the installer series. Dome people say xp series and other people say black series so i don't know anymore.

        • The XP series will offer the most aggressive exhaust tone between the three. The black series is similar to the XP series, but with a black finish.

        Would I be able to do a muffler delete on this if installed, and would it effect my performance negatively?

        • If you were do delete the mufflers in the MBRP XP Series Cat-Back Exhaust, it would require tubing to exit the rear of the bumper. We have not tested this kit with a muffler delete to gather any evidence of performance gains or losses.

            Good Product

            Its a pretty good exhaust system but if you want something louder i wouldnt recomend this. Im actually thinking about going with borla or flowmaster but at the moment im just doing some more research on them before purchasing. Dont get me wrong the exhaust has a a really good tone to it but its not for me.

            Clean Sounds/ Clean Look

            After spending a couple of weeks with this I have to say I am impressed with the sound quality and look of these pipes. After going back and fourth between a couple of options I went with the race version for the low growl. The videos don't do it justice. I will have to say it is much louder that I thought it would be but rather enjoy the rumble. The install was easy once the car was off the ground. I did take my car into a shop to have it inspected for alignment after about a week as the pipes do heat up and expend.

            I bought this mod looking to give my Ecoboost some actual noise unlike stock, and when I first heard it after being installed, I was shocked. The rumble and sound from this thing sounds like heaven for an Ecoboost owner. The sound is great especially after a cold start, and it can be quiet when cruising. Give it some gas and that thing purrs. It’s not obnoxious but also not quiet if that makes any sense. Definitely exceeded my expectations. Some drone at higher RPM’s but satisfying nevertheless. This is a must.

            Great buy!!!

            Love the sound, these videos don’t do it justice. If you wanna great sounding exhaust you can definitely hear get this one. It’s not super obnoxiously loud but trust me, you’ll hear it people around you will hear it. I was between this one and the borla atak but since I live in CA was worried the borla would be way to loud, but also was worried this would be to quiet. So glad I went with this nice super deep tone special when I down shift it revs at 3000rpm sounds great. Get this if you wanna be heard but not annoy everyone. Also took about a hour and some change to install hardest part was getting the other exhaust off super heavy if your alone. Other than that the other parts fit right on.

            Simply not think twice about getting this exhaust. It makes my daily drive that much more exciting. Honestly, it sounds as if it gets better with time. Adds an aggressive note to the mustang. Not a GT and will never be a GT, but this exhaust will give your car its own unique sound. Very deep tone. I'm glad I went with the Race and not the Street. Couldn't be happier.
