    Review & Install Video

    Hey guys, Stephanie with, and this is my review and an install of the MBRP street exhaust, fitting 2011 to 2014 GT Mustangs. We're gonna be talking about a few different things with this exhaust today, but mainly we'll talk about the sound of the cat-back and the install. The install for this is easy, it's a one outta three wrenches in the difficulty meter since cat-backs simply bolt right up, but I'll get more into that later. The MBRP Street Cat-Back is gonna be a great option for the S197 owners out there that are looking for a deep sounding system that isn't over the top or too loud. This is a deep sounding cat-back that doesn't have much raspiness to it and it sounds different than a lot of the other cat-backs that are out there right now. MBRP has included their street series mufflers, and this setup is going to give a sound that's like the MBRP race series cat-back but a touch more toned down for those of you that don't wanna go that loud, as you guys already heard in the sound clips. So MBRP has a few options when it comes to the street cat-back for the S197 GT. They made this cat-back in stainless steel which is what we have here today, aluminized, and aluminized with black tips. Now they all are gonna sound the same, of course, but they will change slightly in price, but I'll mention more about that later. And keep in mind that you also have the option of the race cat-back on top of the street cat-back, and the difference is gonna be in the sound. The street and race cat-back are similar in sound, but the street cat-back is quieter than the race cat-back. But I wouldn't really say that the street cat-back is quiet in the grand scheme of things. It has some volume to it, for sure. This is also a three-inch system that can work with both the stock or an aftermarket mid-pipe. It steps down to two and three quarter inch so it can bolt up to the stock mid-pipe or an aftermarket one that's the same size. So you are seeing a bump up here with the MBRP system. So with any cat-back, what's gonna make this cat-back different from the rest is going to be the mufflers. Like I said earlier, MBRP has their street mufflers on this system, which are a lot like the race series mufflers but just a little bit reigned in. And I'm sure you guys picked up on this when you heard the sound clips earlier. [inaudible] you can hear that this cat-back is deeper than the factory exhaust and even as the RPMs start climbing, this is able to keep the deepness in tone. I keep mentioning this, but the race cat-back is going to sound along the same lines of this cat-back, but just louder. So if you really like the street cat-back from MBRP but it's just a little too toned down for you, then the race cat-back is an excellent choice for you. This cat-back gives a smooth sound and I don't hear any sound distortion. Even though this cat-back does have some volume to it, there's no interior drone. You almost don't even notice that there's an aftermarket exhaust on the car at cruising speeds, so that means you won't have any trouble having a conversation or listening to the radio on the highway. So you don't have to worry about dealing with drone on trips. Overall, if you're looking for a deep sounding system with some volume, then this could be a good option for you. This is powerful sounding but it does also have a deep growl to it. And while it isn't the loudest of the aftermarket options, it's still pretty loud. And so I'm gonna give it a solid two or even a three outta five on the loudness scale. With cat-backs, it really all depends on what you're looking for. And luckily, there are quite a few options out there. So like I mentioned earlier, MBRP gives you three different options when it comes to the street cat-back. This is the stainless steel version which isn't going to be the most budget-friendly of the three options. This is gonna cost between $500 and $600, and you have the aluminized version which is about $100 less, and even the aluminized with black tip version which is gonna cost about $600. But there are benefits to go with the powder coated, or better yet, the stainless steel version, especially if your car is a daily driver. These are gonna give you more corrosion resistance. When it comes to the install, you're gonna be looking at an easy one outta three wrenches on the scale when we look at difficulty. This is considered a direct bolt-on item, so you won't need to cut anything or modify anything to get it installed. All that you're really gonna need is a socket set and a lift would certainly make things easier, but the job can be done on jack stands as well. You're gonna be removing the exhaust from the mid-pipe back, so an extra set of hands can make things easier for you here. You'll be moving over your hangers in the new cat-back, so I'd recommend taking them off with the factory exhaust when you drop that. It will just make your swap just a little bit easier. The whole cat-back can be dropped as one big piece which is why an extra set of hands can really help you here. When you go to install your new setup, it'll probably be easiest to leave everything loose until you have it all lined up and then tighten it down. The cat-back does come with four new clamps, so you don't have to worry about picking those up. You figure on spending about an hour or two from start to finish to get all of this done. Overall, the MBRP cat-back is a great option for those looking for a deep sound but not wanting a system that's going to be too loud. It's a three-inch cat-back that comes complete and is a direct bolt-on install that requires no cutting. You can check this cat-back out some more online for yourself. And for all things Mustang, keep it right here at

    Take It to the Street. The all-new MBRP Street Series Stainless Steel Cat-Back Exhaust System features the most advanced design that has ever been built. While street mufflers make your GT versatile enough for street driving, your 5.0L will roar to life with more muscle car sound and horsepower once you step on the gas. That's due to the high-flow mufflers and 3" mandrel-bent SS tubing improving air flow and expelling exhaust faster. And like a set of shiny new spurs, this elite exhaust system is capped with bright 4" highly polished tips.

    Quality Construction. The MBRP Street Series Cat-Back Exhaust features an improved 3" diameter, 16-gauge T409 stainless steel construction, providing long-lasting durability and superior corrosion resistance. Mandrel-bends, high flow street series mufflers and 4" dual walled 304 stainless steel tips make this Cat-Back System built for the long haul.

    Direct Installation. Complete with all the necessary components for a perfect bolt-on installation, this Stainless Steel MBRP Exhaust will be a direct replacement for your GT's factory installed system. It features one piece extension/over-axle pipes and requires no extra modifications to complete.

    Application. This MBRP Street Series Stainless Steel Cat-Back Exhaust is specifically designed to fit all 2011-2014 Ford Mustang GTs that have a 5.0L V8 Coyote powertrain. This Exhaust also fits 2011-2012 GT500 models.

        Does this system have adjustable tips? I would like to be able to slant them in the slot to match the valance slant. Thanks.

        • The exhaust tips on the MBRP Street Cat-Back Exhaust can be roated, however they cannot be angled up or down.

        If I want to save a few dollars on installation, but I don't have any rentable lift garages in my area, do you think some sitting my car on some tall jack stands will provide enough clearance under the car for me to install these myself?

        • Hello! If you have the mechanical knowledge to install this yourself, you will have no issues doing it on jack stands. I have installed catbacks many times on jack stands!

        Will this work with MBRP 3" to 3" H-pipe?

        • This will work together yes.

        Helpful (0)

        Are these 3 in tubing all the way to where the x-pipe connects to this kit? I'm planning on buying long tube headers and a catted pipe that is 3 inches in diameter. I don't want to have to get a reducer to fit these onto what I'm planning on getting.

        • The MBRP XP Series Cat-Back Exhaust will not be a full 3" all the way through and will step down to a 2.5" at the mid-pipe.

            The product was a very good quality. Easy to install as long as you have a car lift and/or working pit to put them on. Sound quality is great and would recommend this product to anybody at would want to buy them.

            Sounds Amazing

            Love the deep exhaust note. Rowing through the gears is much more pleasant. It does transition to a bit of raspiness above 4k rpm, but it still sounds awesome. Also, the exhaust gets a tad boomy cruising on the highway around 2k rpm.

            Great sound, good fit

            Had these on the car for a couple of years now. Great balance between sound and civilization. Drive sedately and the car has a nice muscular burble. Under heavy throttle, and it scares the grandkids and emits a great throaty snarl. Installed myself in the garage on jack stands. Fitment was very good, but it can be tricky manipulating the pipe over the axles. Would buy these again.

            sounds great, looked great upon install

            i gotta say i have mbrp headers with catted h pipe along with this cat back setup. upon install it sounded great and looked perfect. i dont know about the metal aspect but i didnt expect the stainless steel to start pitting and rusting within 3 or so months of install. mbrp says surface rust is normal. i wouldnt have spent all the extra money when i coulda got cheap chinese knock off exhaust instead of canadians finest.

            The perfect exhaust note!

            Bought this GT kit for my 2012 V6, yes, V6... as the car will be getting twin turbos in the next few months I wanted the extra exhaust flow the GT kit provides. The sound on this exhaust is perfect for me, not too loud, but deep and authoritative. Easy to talk over at cruising speed in a convertible, it wakes up and snarls nicely when you put your foot into it. This exhaust has a tiny bit of drone at cruising speeds, but it's not toman annoying level. Highly recommended.

            MBRP Street Cat-Back Exhaust - Stainless Steel

            I installed a set of MBRP long tube headers with this cat-back exhaust system, both stainless steel. ABSOLUTELY FANTASTIC! The H pipe makes all the difference. Absolutely no drone, absolutely the deepest rumble, absolutely the most aggressive acceleration in town. Truly, what I envisioned my Mustang sounding like. Pricey, but well worth it. I would get better gas mileage, if I could keep my foot out of it.

            Easy install, sounds amazing, looks great

            I highly recommend this to anyone looking for something that's not too loud but still sounds very aggressive under hard acceleration. I have stock headers and h-pipe and fitment was perfect. I highly recommend a lift or high rise jacks when installing the drivers side h-pipe to muffler piece as you need to angle it down far enough to clear some stuff.

            Best choice

            Chose this exhaust on price and everyday use without waking the dead . It was coupled with UPR stainless off-road X , below 2000rpm normal traffic driving it had nice tone , lightly deep rasp ..... Once you mash on it , it comes alive and then the dead awakes !!! Music to your ears , so many compliments cruising 70-75 down HWY . People flagging me down to say how good it sounds ! Auto car , Steeda CAI , Bama custom data log tune 93 oct . Car made 380rwp ....I'd buy it again
