    Review & Installation Video

    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.

    My 2011 mustang gt has a 3" bassani cat back. It was on the car when I brought it and do not have the original exhaust. I have added a off road xpipe and its now to loud. Will these mufflers mate with the bassani over axle pipes that are currently on my car?

    • The MBRP Installer Series Axle-Back Exhaust is a direct replacement for the factory exhaust and it will bolt up to the stock location. It may not be a direct bolt on to the Bassani Cat-Back and X-Pipe Combo, item # 31111, (https://www.americanmuscle.com/bassani-catback-xpipe-1113gt.html).

      A best buy

      I bought this because I wanted to get rid of the factory heavy mufflers, more aggressive sound, and spend as little as possible. This axle back worked perfectly and looks nice also. I had the old out and this system in in a little over an hour on the driveway.

      Solid Budget Exhaust

      I've got 150k miles on my '12 GT and wasn't looking to spend a lot to get a deeper rumble out of Coyote engine. The MBRP Installer sounds great at a very reasonable price, I'm thrilled.

      Just the right noise level

      I used to have pipebombs, which were obnoxiously loud, but I wanted something less noisy. These sound better than stock, without being obnoxious, and there is no drone anymore.

      Fit and finish are great for the price. Installed easy and sound great. If you would like a little more sound without the drone and volume while cruising, these are perfect.

      Some difficulty in removal-Easy to install

      The system is of good quality. Mellow tone. One of the exhaust tips had a dent but it is hidden under the car. It took a little longer than I thought (about an hour and a half), I was having problems removing the original installed mufflers as directed by the installation instructions. I finally loosened the exhaust pipes at the X connection and that gave me some wiggle room to remove the old exhaust. Installation was fairly quick and simple. The muffler hanging system of the MBRP Axle Backs exhaust are installed to allow easy access and mounting to the rubber mounts. Overall it is a good system and worth the price paid.

      mild difference in sound

      Very lightweight compared to stock mufflers with a very nice finish and the fit was perfect. The sound was exactly what I was looking for, just slightly louder than stock. Above 4k rpm at wot, they do get a little raspy tho. Great option for the money for sure.

      2014 Mustang Convertible V6

      Shipping was super fast. I had a shop install them and as I watched the install the passenger side went on like a breeze, the driver side seemed to take a little longer and was a pain to line up. The best they could do was fine for me. In all fairness the stock driver-side muffler always looked a little off to me so you may not have this issue. If you want to see how they look check out the picture section I uploaded a few pics of them installed. To the sound... Nice! Just wanted a a muffler that added some rumble without waking up the neighborhood and NO pop, ping raspy sound coming down from revs. I hate drone and these, although not completely drone free at 65-70 as they say it very, very low and the best you're probably gonna get. At startup you'll get a nice deep low note and as the car warms up it drops even lower, just plain sounds good idling. When you hit the gas they sounds great and as you come up to speed they settles down to a nice low tone. On the freeway you can barley hear them.

      A beatiful tone, really , with chromed headers ... but i painted black with an high temperature spray (up to 800 degrees) to preserve surfaces from dust and salt and looking awesome (check my photos)

      Good product, very good price

      Great sound, deep, rumbly but not staccato as some Coyote axle backs. There is no drone really, maybe a slight humming burble @ ~1800-2000 rpms/~65-70mph. It comes alive when you get on the gas and push it. Lovely. Loud enough but not obnoxiously loud. Sonic expectations were met quite well. The stainless extensions are high quality but the built in clamp can be tough to reach at install. It is pretty rough in appearance and be careful with the bracket posts. They seem to be just sawed then snapped off so the sharp edges can cut/scrape skin. It also scratched my bro's seats - the box is big. They need to round those off. They will poke through the box. Install on my 12 GT conv was not as easy as in the vids. No wonder they recommend taking out the mid pipes first. I didn't and went via taking out the bracket mounts. Also, you will need to reuse the orig clamps. I wish MBRP just included them. The driver's side bracket was tougher to reinstall. Once the mufflers and brackets are installed, they felt pretty secure. I hope the alum steel lasts long enough as I do not plan to do this again.

      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.

      Axle-back

      Best mild sounding exhaust...louder than stock but not crazy loud with minimal interior drone. I had tack weld one side...no matter how tight the clamp the exhaust would move side to side.

      The MBRP PRO series sounds very quiet has an old school muscle tone to it but not loud enough for me. I don't recommend these if your wanting loud tones.

      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.

      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.
