Review & Install Video

So MBRP's Pro-Series that we've got here today is gonna be a good option for any Coyote owner out there that wants to improve their exhaust note without getting too loud, and without too much drone, all while not burning a hole in your pocket. Now axle-backs for the '11 through '14 are gonna install with little to no effort at all. For that, you are looking at a very straightforward one outta three wrenches on a difficult meter here, about an hour's worth of wrenching, and I will show you how coming up soon. So right out of the box, guys, what you just heard is definitely gonna be on the quieter side of the spectrum here. And I'm gonna be giving this a one outta five on the loud or the wake the anybody scale here. These mufflers will ditch your heavy factory setup for another chambered style muffler, but one that's gonna be giving you a slight bump in tone and volume over your factory cans, while shading about 15 pounds off the back of your car. Now with that said, this quieter axle-back is still a huge improvement over the factory muffler, as those stockers just don't do the Coyote and justice, and let's face it, honestly just make any Mustang sound like any of the car out there on the road today. So if you like the relative volume of your stock system, you like the cabins pretty quiet and livable, but you wanna make the motor actually sound like it's supposed to, these are gonna be perfect for you. And these are gonna give you a marginally decibel level increase, while not creating too much drone, you are still gonna be able to have a conversation in the car and enjoy the long drives. But from sound to steel here, guys, the Pro-Series is made out of a three inch aluminized stainless steel tubing, which is considered entry-level in terms of the materials. And that's directly going to affect how affordable this system is. Now it's worth pointing out that if you're on the coast, somewhere where your're gonna be seeing snow a little bit more often than not, or if you're just in a wet part of the country, aluminized steel may not be the best material in terms of resisting corrosion. Now it's gonna be inherent that any exhaust system is gonna discolor or rust over time. And this is something that will likely turn a little bit faster than stainless. But with that said, it's really not gonna be visible as it's gonna be under the car, and it's really not something that will keep me up in the middle of the night. But where it counts here, you are gonna be getting a very nice polished set of 304 stainless steel tips, and they're always gonna look great, they're not gonna rust or corrode, and they will polish up nicely. Additionally, they are gonna be etched with MBRP's logo, which is a nice little touch too. On the flip side here though, if you are overly concerned about that finish under the car, MBRP's stainless series will yield that same exhaust sound as it's gonna come with the same mufflers, but the build quality is gonna be 304 stainless, and expect to be spending over 500 bucks to get into those. So for the money here, I think it's very aggressively priced for what it is. And if you're the owner that's after a slight bump in volume and tone, but looking around at the same price range, you are gonna see there are other options from Heartthrob and pipes, which are gonna be , they will inherently be louder, but the materials are gonna be slightly better. At the end of the day here, guys, it's ultimately gonna come down in sound that you are after and what you wanna spend, though. But installation wise, like I said earlier, axle-backs are really a piece of cake. They install in under an hour with basic hand tools. And for that, it is gonna warrant an easy one outta three wrenches on our difficulty meter here. Now some tools for the job are gonna call for a pair of jack stands, a basic socket set, a ratchet, pry bar, Channellock pliers, and some WD-40 or any type of spray lube to hit your hangers. So you wanna begin by loosening up the clamps connecting the exhaust pipe to the muffler, and then move the muffler lose from the over axle pipe. Once that's done, guys, it's really just gonna be a matter of getting your MBRPs in place, clamping everything down, clamping your tips down, giving your work a good once over, and then you are ready to make some noise. So that's gonna wrap up my quick review with MBRP's Pro-Series Axle-Back, fitting the 2011 through 2014 Mustang GT, that can be found right here at americanmuscle.com.

    Lots of exhaust options for this car, and I chose the MBRP based on reviews, price point, ease of install and drone noise. While the new sound is much deeper and fuller than the stock, you can still talk to your passenger or hear the stereo. Perfect! Noticeable difference in power too. Took a bit over an hour to install with a jack and stands. Bonus for me was a rebate available when I bought them. That helped my choice too.

    Very Pleased

    My brother and I jacked the back end up and it took about an hour and a half to complete the install. Hardest part was getting the stock mufflers off. I would recommend having some wd-40 to spray the rubber hangers with, makes them slide out easier. After I put the new ones on my 2014 5.0, the car sounds great. I chose these because I did not want the car to be too loud but wanted the deep rumble associated with muscle cars. Barely any drone at all. Would definitely recommend these to anyone who wants a pair of mufflers that make the car sound like a true muscle car.

    Paired with Cat-Deletes

    To start off, I never heard the mustang with the stock mufflers. When I bought it, it had the Roush axle-backs (ridiculously loud btw) and some cat-deletes. So I can't really compare to the stock mufflers. However, I decided to get these because the Roush axlebacks were too loud for my taste, specially with the cat-deletes (I'm assuming that they wouldn't be as loud with cats on). The MBRPs almost hit the perfect spot. Awesome muscle car rumble note all throughout the RPMs. If only it had the same exhaust note, just slightly louder. Sometimes my dad says "oh I didn't hear you pulling into the garage".... not cool. However, you can definitely hear these growl once you step on it. There is drone at 2k rpms, specially without the cats. I did have to bend only one of the hanging arms to make it fit. I am planning to add some aftermarket shorty headers, hoping to obviously get better HP but also to help the exhaust volume. Hopefully the drone doesn't get louder.

    Exactly what I was looking for...

    After a lot of research on axle back exhaust, I took a chance with the MBRP based on reviews and YouTube videos ( cause American Muscle does Not have a video on the MBRP Pro) . I got what I was looking for, the nice bossy muscle car low rumble and prescense with very low drone when you are cruising around 2000 rpm. You can talk and listen to music with no problem.

    Great Budget Exhaust Option

    I chose the MBRP Pro-Series on account of the price and the reviews that state it is not as obnoxiously loud as most budget axle backs. My first impression of the quality was OK. The stainless tips look fantastic, but the welds on the muffler are very porous. This isn't a major issue though and I can accept it at the price point. The fit is phenomenal. I have had Pype Bombs in the past that required significant modification to fit correctly. These went in perfectly in minutes. They are however a bit louder than expected. Not nearly as loud as Pype Bombs of course, but loud enough to mildly annoy neighbors and drone a little bit on the highway. If you are looking for a totally drone-free system you will likely have to go for GT500s or shell out for the higher dollar offerings (Borla for example). That said, these are certainly tolerable, but I wouldn't suggest them if you take long road trips often. The tone is nice and deep and it isn't too raspy, despite the fact that my car has a 3.5L EcoBoost swap (an engine that usually sounds like angry canned bees). Overall, I would say this is easily one of the best budget exhaust options! Additional Details: -They shed a total of 14.8 pounds from the car. But bear in mind that the rear of the car is not the best place to shed weight. -They do offer enough clearance for a trailer hitch. The fit in this respect is similar to stock.

    Good value, good sound

    I bought these for 3 main reasons: I wanted something that was relatively affordable, that would have little to no drone, and that would be louder but not so loud that my neighbors would hate me (I'm looking at you, race exhausts). So as far as price, these are a great option. There aren't many non-race or non-muffler delete exhausts near the price. I had them installed at a shop for about $80 and 45 minutes time. They lined right up without issue, so I'd say the fit and finish are excellent. There is a little bit of soft drone at 2000 rpm, and the sound is generally a little boomy between 1000 and 2000 rpm, but I'm a picky guy and the drone is still not at an annoying level; mostly just noticeable, not unbearable. Many people will probably like this as it gives it a deep, muscle car sound. The exhaust note takes on a more refined and well-defined staccato as rpms rise, but I wouldn't mind a little more rip. Its still a good improvement over stock. Overall, this is a nice axle back system and is probably nearly perfect for people trying to improve their exhaust note without getting too loud or irritating their neighbors. However, I'm getting tempted to upgrade to either the BBK Varitunes (I love the pops on throttle lift-off) or Corsa Sports (Corsas sound amazing but the price is tough to swallow when you can get something like this for less than half the $$). But back to these: they're a nice system for the price and I have no issue recommending them.

    I like this exhaust.

    Well ordering couldn't b easier.. the time it took to arrive at my door, I thought they used a mustang to bring my exhaust so quickly.. ok.. installation was a breeze, old out and new in 30 minutes.. not my first exhaust.. I have jba Lt headers,jba hi flo cats. Have slp straight pipes wow loud.... So to tone down I wanted something not teeth rattling loud..I went with mbrp cause it said mellow deep tone..much deeper than stock. Much louder when you gas it.. but very nice driving around deeper tone but volume at 1300-1800 rpms is great... very little drone but it sounds mean when you want it to.. for the money it's a great exhaust.. with my Lt headers n hi flo cats it's the perfect balance...

    Easy install, love the tone!

    Like many I spent months on YouTube, forums, Facebook pages, etc listening to the endless exhaust setups out there. I initially had muffler deletes (custom made from an exhaust shop) but once I threw in some cat deletes it was ridiculous and with NO tone. I needed an axleback that wasnt too loud....but also not too quiet. The mbrp pro series are just about right. In all honesty I wouldn't mind a hair louder but for around $300 I'm not complaining and Ill be removing the stock resonators anyways which I believe will give me the perfect sound level. With an h-pipe they offer a very deep muscle car tone. They're deep, but don't drone. I can hold a conversation perfectly fine. On the outside they sound perfect. I had a friend drive up and down the street and was very happy with what I was hearing. Install is probably the easiest thing I've ever done. It can be done without jacking up the rear but just do yourself the favor and Jack up the rear. The added room makes it easier and faster. "Hardest" part is forgetting to put some wd40 on the exhaust hangers and fighting with them a bit Lol.

    Nice mellow exhaust

    These mufflers are a nice upgrade from the factory mufflers. If someone is looking for a muffler that's not too loud these would be a good choice. They have a good deep rumble, and at highway speed they are quiet in 6th gear. The 4 inch tips look great. They are definitely good for the price. Also a little drone around 2 rpm.

    Deep muscle car rumble

    It took me a good 6 months to make up my mind on what I wanted to buy, my demands were affordable price, deep muscle car burble, and no raspy notes. I compared between this Flowmaster Thunder, Roush, and GT500 axle back setups. Many of these had a raspy note from the videos I saw online, and the GT 500 did not sound loud enough. I think I found the one, the MBRP Pro Series!!! I will post a video online soon so you can hear the difference, (pics are already up), but these are a tad louder than the GT500 without waking up your neighbors, it has the deep muscle car rumble that this generation mustang should have sounded like from the factory. I have not tested for drone yet, but I will update this post to report on drone.

    Great Tone

    Just what I was looking for! It's a low growl that roars when you get on it, not obnoxious by any means but it starts to get close at 3-4rpm. Ez install if you've got the basics, if youre old exhaust is rusted on then use PB blaster and banging with a hammer or ratchet(kinda hard). And loosen the rubber supports with soapy water from a spray bottle. I lifted my exhaust from the middle, with a jackstand, so it was easier to slide the old muffler out. All in all with rusted mufflers to bang on, took about 3 hours

    Good deal.

    Good product for the low cost. I really like the clamp on tips. You can position them however you like and they polish up nicely. The sound is slightly louder than stock without any drone at cruising speeds. You must use factory clamps. Some finessing is needed to seal them to the factory pipes. Overall, I'm happy with them.

    Nice Sound

    Was really the sound I was looking for. Deep tone with a classic muscle car rumble. No poping and such. No drone. As far as install - getting the stock pipes off was a PITA. Getting these on was a breeze. Came packaged very well, wrapped and foamed in good box. I also have MBRP products on my diesel truck so know the products and the company. Good stuff for a reasonable price.
