    Review & Installation Video

    Review & Install Video

    The Roush axle-back for the S197 V6 will certainly be for the owners out there who want to be heard, as this top-rated system will also be top-rated in the volume category as well. Now, you can look forward to a mix of both 409 and 304-grade stainless steel for right around $500 here for the axle-back, and the simple bolt-on installation will get an easy one out of three wrenches on the difficulty meter. But we will have a little bit more on that later on. So the Roush axle-back that we have in this video, much like it's 5.0 counterpart, will be one of the most popular axle-backs for the 3.7, and by a pretty wide margin. In fact, guys, you're looking at over 100-plus five-star reviews for this axle-back here. A big reason for its popularity is, of course, the loud and aggressive tone, but also the relatively affordable price tag when compared to some of your other options in the category. But let's not waste any more time. Let's dive head first into that unique Roush tone that you guys all heard with our sound clips at the very top of this video. What can I say? If you want loud, the Roush here is certainly not going to disappoint. Going to my highly official and highly scientific Wake the Neighbors scale, I have the Roush coming in hot at a strong four out of five on that one to five, or one to Wake the Neighbors scale. Keep in mind, this is still with those factory manifolds still in place. Eliminate those with some aftermarket headers, get rid of the cats, and you are going to effectively peg that Wake the Neighbors scale. Now, I did hear this thing a little bit inside the car while cruising, but I wouldn't categorize it as drone. It shouldn't be anything that will deter possible buyers out there from slapping this onto their V6. But one thing that really does stand out to me about the Roush axle-back that we have here is kind of how it changes or almost transforms the sound of that 3.7 that a lot of us are very familiar with. Now, in my opinion, this thing gives that tone a little bit more of a higher-pitch characteristic, and it's something that I don't really hear with a lot of the other aftermarket systems out there. It is also something that a lot of our customers bring up in the Customer Review section. So check that out. Again, 100-plus customer reviews with the Roush axle-back, and it's just a great way to get a better feel for what you can expect when bolting this thing up to your 3.7. So how does a Roush system achieve that very aggressive, very unique tone? Well, just like the very popular 5L system out there, the star of the Roush axle-back for the V6 cars will be the hollow-chambered mufflers that Roush does incorporate here. Again, it will allow for all that volume, but without any internal packing. So you don't have to worry about the sound of this thing kind of changing on you over the years. But talking about the construction a little bit more here, guys, I did mention earlier, you're getting a mix of 409-grade and 304-grade stainless with the Roush axle-back, and that is the case here. A majority of the system will be the 409-grade stainless steel, including your tubing, the hollow-chambered mufflers we just talked about. But the tips themselves, they're actually going to be made from 304-grade stainless, which is really what you like to see. Right? Because that's what you're going to be seeing the most of, and the 304-grade is definitely better at reducing corrosion compared to the 409-grade stainless steel. Now, the tips are actually finished off in Roush's unique chrome flashing process, which just essentially is going to make for a much more durable finish over the years. At the end of the day, listen, guys. It's Roush. Right? They know what they're doing. They've built some solid stuff over the years, and their products are always very well-made and fit like a glove, which does lead me into the installation here. Again, guys, very simple stuff, one out of three wrenches on the difficulty meter for the S197 axle-backs, maybe 30 minutes to an hour of your time, depending on your setup and how fast you work. As far as your tool list, well, a basic socket set really is going to be the majority of your tools here. I always like to recommend a little spray lubricant as well, to help you with some rusty bolts and those rubber exhaust hangers. Then, of course, just give yourself a little bit more room to work underneath the rear of the car with a jack and jack stands, lift, or race ramps if you have them. Getting started, you need to remove those factory cans first. So go ahead and grab your socket set, remove the clamp closest to the muffler, and then a few bolts on the exhaust hangers connecting the hanger to the actual chassis. At this point, you can drop the factory mufflers down from the car. Transfer those factory hangers over to the new Roush axle-back exhaust system, and then get ready to lift it into place. Now, me, personally, I always like putting one end on the rubber hanger first, before tightening up the clamp closest to the muffler here, just to kind of take some weight off of your shoulders. So go ahead and do that, and loosely tighten that clamp, guys. Don't overtighten it yet, because you will need to make some small tweaks once you get everything bolted down. With that said, go ahead and bolt down the rest of your exhaust hanger, bolt on that tip, and then kind of get it situated right where you want it, in the opening in that rear bumper. Once you have everything in place, go ahead and have a buddy kind of hold that tip into place, hammer home that clamp nearest the muffler, and your installation is complete. So if you want a very loud and very unique tone for your 3.7-powered Mustang all for right around $500, definitely check out the Roush axle-back, right here at americanmuscle.com.

    Aggressive Muscle Car Sound. Let everyone know your 2011-2014 V6 has arrived with the aggressive sound of this high performance Roush exhaust. This innovative new Roush exhaust system features a hollow chamber muffler that results in increased air flow and a unique sound, with no in-cabin "boom" normally found with performance exhaust at cruising speeds.

    Quality Roush Construction. Constructed from 409 stainless steel for a durable long life, the Roush axle-back exhaust system features two unique chambered mufflers with 304 stainless steel tips. The tips are finished with a new chrome flashing process that is resistant to discoloration due to exhaust heat.

    Application. This Roush Performance Axle-Back exhaust system will fit the 2011-2013+ V6 Mustangs with the stock V6 rear valance or the Roush Rear Valance.

    • Hey Dalton, Installing an axle back does not require a tune because it is a change in sound and not necessarily performance.

      Best sounding mufflers for your V6

      I got these because of all the reviews saying how nice and loud they make your v6 sound. Granted, I wasn’t completely sure I’d love them but after I bolted them on and started up my car, I instantly loved them. I 10/10 reccomend these to anyone out there with a v6, especially if you’re looking for a sound that’s not just loud, but also gives it somewhat of that muscle car sound that it deserves.

      Who needs a V8?

      I was a little skeptical at first having not done much with my Mustang. But let me tell you that this makes your V6 sound absolutely amazing. I did the install myself and took about an hour and a half. And that's with literally 0 experience working on cars, so the install was easy, to say the least. After installing you probably couldn't tell that it's a V6 from then on. When you want it to be loud, you'll wake the neighbors, but if you want to be quiet, it's easy to do so. This is perfect for those early risers who still want to show off. I 100 recommend this.

      Good for volume... sound is eh

      Let me get my biggest dislike of these out of the way: they're high-pitched and a bit raspy for my tastes (and a few others I've asked). It's good around the low RPMs, but get anywhere where you're getting into power, and the high-pitched nature of them is noticeable. Sometimes, I felt like it was just loud for the sake of being loud, without an exhaust note that feels like it fits a Mustang. I installed short headers recently, which helped a little bit, but the 2.5" piping that the exhaust keeps all the way through means it'll always sound high-pitched. If they opened it out to 3", it might have sounded really awesome, but I guess it would've been more expensive too. Everything else though, is great, especially for the price. The Roush axle-backs are great for a quick way to get the 3.7 sounding more respectable. Great volume and you can hear it growl more, but it's not overly loud; just about right. Interior drone is minimal, you get used to it quickly (even with short headers). Also I, personally, love the pops and crackles. Kind of made up for the 'meh' exhaust note. Fit is great. For most of few years they've been on my car, they were in good weather, but it's now just been through a northeastern winter with fairly frequent underbody washing(daily driven car). I've taken them off to replace them with a new axle-back (RTR Street Spec), and the Roushes are still in very good condition. One last thing I noticed just when switching out the Roush for my new Magnaflow is that the exhaust tips are also made very simply in comparison. Noticeably sheet metal, formed in a way to look nice if you don't look too closely at it with the edges rolled back in to give a rounded edge, as opposed to being a fully-formed piece like the Magnaflow/RTR. I wouldn't say this is a negative really, since I'm sure this is one way that the Roush exhaust price is kept down, but just something to mention, since it does look nice if you don't look at it up close.

      If you're having doubts, don't!

      I've been eyeing this exhaust for months and after saving enough money, I finally bought it. Shipped pretty quick and I was looking around for a place to install it that didn't charge me over $200. I'm not a mechanic or anything but I know a thing or two about cars so I decided to watch some YouTube videos and go at it with the manual. Surprisingly it was really easy! It took me a couple hours but that was it. I haven't regretted buying it. It gives me that deep grumble I love and completely changes the car in my opinion. If you're having doubts on whether or not to buy this exhaust from others, you'll definitely not regret this one. It can be loud at sometimes but it's definitely possible to drive this quietly. Best purchase I've made for the car, no doubt.

      Great choice

      After months of deciding on the proper axle back for my 2013 mustang, I’m glad I picked roush. Perfect blend of rasp, deep tone, and pop on downshifts. Wakes up the car for sure, perfect first mod, and the install was fairly simple aside from the rusted on stock bolts

      Good exhaust tone

      These roush axle backs sound similar to the borla s types, but the drone is really, and I mean really bad in the cabin. The price is a bit steep considering the only thing 409 stainless is the tips. I would expect roush to have the whole thing fully stainless. Other than those two things I have no other complaints.

      Aggressive and Awesome

      I have only had these on my car for a few days now, but I am completely happy with my purchase. I tried to install myself, but the stock exhaust clamps were so rusted from Chicago winters I had to go to a shop. They had to cut the stock exhaust off. After that it was an easy install. The sound is very aggressive, deep, and loud, but not too loud. My favorite part of having these is the pop when shifting. If you buy these you won't regret it.

      This was my first accessory purchase for my son's 2014. Installation was pretty easy. It was a nice father-son project. There is no drone, but there is a nice cackle about 3000 rpm or so that makes you smile every time. I am a detailed person so one concern was having the tips exactly right in the cutouts. No problem. Highly recommend. Next up some Cold Air coming in. PS The video clips were on point.
