    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.

        Does this exhaust require a tune? Would it be more beneficial to update your tune specifically with these axle backs? Thanks

        Will I need a tune if I have a roush cold air intake and these exhausts?

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

        10-12 Roush Rear Valance I drive a 2013, do I need the 10-12 Roush Rear Valance?

        • This exhaust will fit with the stock factory V6 rear valance on the 2010-2013 V6 Mustangs. Unfortunately, the Roush Rear Valance won't fit properly on the 2013 however.

            Extremely loud, depending on setup.

            With BBK shorty headers and a BBK x-pipe, this exhaust combination is very loud. Sounds good. In this setup, be prepared for substantial in-cabin noise. No video will serve this justice - not even close.

            Honest Review

            Only other mod I have is an Airaid CIA. The fit on these is perfect, just put them on the hangars and they were centered with the stock exhaust holes. Some reviews say these are way too loud, and it made me skeptical but they must be always on the gas. Yes these get loud with hard acceleration but with easy to moderate accel, they have a very pleasing rumble. If you dont want loud then why are you looking for an exhaust... From looking at the inside it seems they act like a strait pipe at high rpms. Not too loud when cruising at 80mph and quiet when coasting or maintaining speed. My favorite parts are startup and dropping gears. Put the car up on jacks loosen pipes from H-pipe and unbolt the forward hangars. Fairly easy install, definitely worth it.

            Was looking for a way to make my car sound amazing and this did just that, it’s a tiny bit loud in the interior when steadily accelerating at around 60-65 but if you love hearing your car like I do it’s not a problem at all.

            Roush Axle-Back

            As reported by many, the installation was very simple, but I would suggest using a lift and someone to assist you. The hardest part was getting the old exhaust out. From the initial start of the engine I was pretty much in love. I love the exhaust note and fit of the chrome tips. I'm glad I finally pulled the trigger on these.

            The hardest part about the install was cutting the old bolts off the clamps once I snapped the heads. Total install time was under two hours and we weren't working hard. Relaxing Saturday project in my buddy's garage with the car on a lift. Very sweet tone. Loud and aggressive when you want it, a deep rumble otherwise. Couldn't be happier with the product.

            This exhaust was better than expected! I wish I had purchased it sooner. It's as loud as I thought it would be, but sounds even better than I dreamed. The only drone experienced is going up a hill while cruise control is on, on the highway. Installed took about 45 minutes.
