    Review & Installation Video

    Hey everybody, I'm Justin with, and this is my quick review of the MBRP Installer Series Axle-back Exhaust, available for your 2012 through 2014 V6 Mustang.So this is going to be a super affordable axle-back exhaust system for any SN97 V6 owner out there looking to add a little bit more volume and a little deeper tone compared to your factory exhaust. Now MBRP, traditionally, are going to come in on a lower side of the price range, and their Installer series is definitely designed for you owners out there on a tight budget but still looking to add a little bit more volume. Now, in fact, this is actually one of the most affordable axle-backs currently here on AM, with only the Pype Bomb coming in a little cheaper. Now, a big factor in keeping the price down with the Installer series is the selection of materials. Now, to keep things reasonable, MBRP utilizes heavy gauge aluminized steel in favor of the more expensive 304 or even the 409-grade stainless steel. No real performance drawbacks from this, but again, if you are looking for the long-term durability, this might be an issue with the aluminized steel, especially if your ride sees a lot of road salt during the winter months. Now because of this, MBRP is only going to offer you a three year warranty with the Installer series, as opposed to a full lifetime warranty with some of their stainless systems. So if long term durability is going to be a big concern for you, you might want to check out the Pro Series axle-back from MBRP. Essentially the same kit I have here, it's going to sound the same, but you are getting that full stainless steel construction. Going to cost you a little bit more, but again, you are getting the lifetime warranty.As you guys heard at the top of this video, this thing definitely delivers when it comes to sound, and in my opinion, delivers a very enjoyable tone. Not too crazy loud or anything, so for that reason, we'll call it a strong two out of five, maybe even a three out of five on my one to five or one to wake-the-neighbors scale. Now despite what V8 owners might say, I think the 3.7 is a good sounding motor, and this thing is going to deliver plenty of bang for your buck when it comes to sound and that should be one of your top deciding factors when choosing a system for your ride.Before we get into the install, let's quickly run down the materials. Again, for the most part, full aluminzied steel for the construction with the exception of the four inch tips, these guys are stainless and etched with the MBRP logo. But as for the rest of the system, again, aluminized steel, two and a half inch tubing, MBRP's high flow mufflers. The welds could be a little bit nicer but again, this is a value system.As for the install, well, it really couldn't be any easier here guys. We'll call it one out of three wrenches on the difficulty meter, maybe an hour or two in the garage or driveway before you're making some noise. Full bolt-on install, no cutting or modifying needing. Maybe a socket set as for the tools, and maybe you want to get the rear of the car in the air slightly just to make the install a little easier.Wrapping up, the Installer series from MBRP, in my opinion guys, one of the best value axle-backs available here at AM. If you don't mind that aluminized steel construction, you're going to be getting a great sounding kit for around the $300 mark. So be sure to learn more about MBRP for your ride here at

      4 2012 V6 - Avery044 Installation Time: Afternoon

      Fantastic and Annoying

      Installation: It's very easy to put this pair of mufflers on my cars. It only spent me half hours including adjustment. However, it was extremely difficult to take the stock mufflers out. I might do it incorrectly. There were just not enough space to move the mufflers for taking the hangers out of the rubber mounts. For completing the work, I had to loose the swaybar to gain extra 2 inches. If you have the right tools to separate the hangers from the mounts without moving the muffler around, it should also be done in a half hours. Performance: When the engine is idling, my V6 sounds like an old carbutor V8. You can hear the explosion from the combustion chambers. Also when you reach 4k RPM, it sounds really seriously. For this two points, I give it 5 stars. Issues: It drones. I'm not sure about other 3.7 Mustang. On my 2012 V6, it drones on highway, but it drones less than the Flowmaster Axle back I used to own. I'm okay for drive it for 10 hours, but it will be a very uncomfortable trip. The only way to get away from the drone is when I release the gas. Once you put foot on the gas before you pass 4k RPM, it sounds as ricer as most of after market mufflers. For this two points, it loses one stars.

      Gave wife's V6 more rumble.

      Wife loves the race red premium convertible I gave her for an anniversary present a few years back. Only "negative" was that it didn't "rumble". For our latest anniversary, I got the MBRP installer axle back exhaust. I took car to my son's shop on the pretext of needing an alignment. Start to finish took less than an hour. Quietly put car in garage, and asked her to run to the store for me. When she first started it up, and heard the "rumble", she was as excited as the day she got the car. As her car has never seen snow (even though we live in western NY) and only sees rain by accident, the aluminized steel was adequate for her. I did prime and paint with VHT before installing, but this was more for cosmetic purpose than anything. Car is put up for the winter. To summarize, we are quite happy with this system. The exhaust note is perfect for us. She did NOT want the car to sound like a "garbage truck".

      Exactly what I wanted!

      I get off work late so did not need to wake up my angry neighbors with a crazy exhaust. Wanted something deeper and just a tad bit louder than stock and that’s exactly what I got. Easy install, did it on ramps in my garage in about an hour

      Love them, nice price

      I have about 70,000 on my car, and the removal of the mufflers seemed too much of a pain after I started working on it. Got lazy and brought it to local muffler shop, and had them put on for $80. Best money I ever spent.

      2 2014 V6 - Frankie Installation Time: Afternoon

      Not a good fit

      Because exhaust pipe is flared at end, about 2 millimeters of muffler pipe hung over exhaust pipe. In my opinion, that's not enough. And after running on it for a couple weeks, it worked loose. Had to get back down there, and cut a connector from auto parts place, so it had something to grab onto.

      Rich Mellow Low rumble

      2014 V6 w/ Spectre CAI and BBK 73mm Throttle Body. MBRP Installer series Axle-back exhaust system I cant believe that it came in VERY quickly. I ordered it on a Tuesday, it came in the next afternoon! I recommend calling in to make an order. You will get your order quickly. Also, If you’re Military ask for the discount. After install, I've noticed a slight change in throttle response. MBRP Installer Series gives a deeeep mellow exhaust tone. Which is cool if you prefer subtlety for your Mustang. But, If you want something that makes lots of noise and turns heads, i would recommend looking elsewhere. Because this IS NOT the axle-back for you. Although, there is NO DRONE. So the cruise quality is pretty chill. Overall, its a good system for those looking for moderate loudness (2:5). It definitely gives a Deep Low Rumble which may be a good choice for your daily.

      Good Product

      I was looking for something to give a better sound than stock without being too loud or obnoxious. This fits the bill nicely. You can certainly hear it but exhaust tone varies nicely being louder when you push it but quiet when you don’t. You can see through the muffler, perforated straight tube inside so should flow well. Tips look great and mufflers smaller and lighter than stock. Overall happy with the purchase for my 3.7 S197. Took about hour and a half to install myself, very straightforward.

      Nice Sounding Exhaust for a great price

      Was looking for an exhaust for my 14 v6, and was mainly looking for something louder than stock, but nothing crazy loud. This is my daily and I'm not trying to wake neighbors when I go to work every morning and was looking for something that didnt drone. Also was not trying to spend almost a grand for axle backs. These were priced great @ a little over $300. The actual volume of the MBRP axle backs is louder than stock, but not stupid loud. I think most of the reviews here on american muscle do it justice, most say its a good volume but not too loud and I'd say that's accurate. You know its there, and it sounds good when you get on it, with no rasp or drone in the cabin. But if you want something very loud this will not fit your needs. Best way to put it is, its a refinement over stock. If you are on the fence about build quality, on mine the welds were good, no air leaks, and the tips are nice quality w/ MBRP stamped on them. Looks better than stock for sure. For the price you can't beat it. I would probably get this exhaust again.

    Do these drone real bad? I am looking for something to replace the competition style mufflers that came on my Mustang. I also want something quieter than what I have. I currently have a terrible drone starting at 1800 rpm. It also gets way too loud for little one who rides with me all the time.

    • The MBRP Installer Series Axle-Back Exhaust is designed to reduce drone as much as possible. These will be one of our most drone free exhausts.

    Are these legal for sound/ emissions in California?

    • They are legal in terms of emissions, however we do not have data on decibel level and legality in terms of sound compliance.

    Does this come as a pair?

    • The exhaust is sold as a pair, (1) for the right side, and (1) for the left side. Enough for one vehicle.

    Is this legal in California

    • Exhausts generally are street legal. It can honestly depend on the state and their laws though. With how strict California is, we highly recommend reaching out to a local shop or state ordinances to confirm if the part will be legal in your state.

    Will these pass emissions inspection?

    • Usually most axle-back exhausts should pass emissions. With that being said, it can honestly depend on the state you live in and what their emission laws are. We recommend checking with your state ordinances.

    I have a 2011 v6 mustang that I have recently installed BBK long tube headers, BBK catted x-pipe to go along with roush axel backs, BBK 73mm throttle body and typhoon CAI with a bama tune. The only concern I have is it being way too raspy and loud. The car sounded great with the CAI, axel backs, throttle body and tune but once I added the long tube headers and catted x-pipe it got really raspy and loud. What should I do, should I put resonators on the xpipe or buy new axel backs? I hate the raspy sound and people have been saying it doesn't sound good. Hopefully someone can answer my question. 1 answer
