- How to Install Roush Axle-Back Exhaust (11-14 V6) on your Ford Mustang
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.

Great quality, perfect fit- cool sound!
These really change the exhaust on the 3.7 - has a nice clean burble to it now- deep, rumbly and crisp. Install is very easy - one pointer that I didn't see in the AM install video - make sure you loosen the 4 (2 on each pipe) 15mm bolts right at the H pipe. Really easy, they point down and only takes a minute. That makes the job truly 15 minutes per side once the pipe can easily slide out of the way for you: otherwise it's a wrestling match to clear the axle and hangers. Sound is so nice now ! I also bought some BBK headers - they should pump up the sound even more I hope. Installing them tomorrow. Great shopping experience - well packed and really happy- thanks AM !Helpful (0)

SOUNDS AMAZING! INSTALL SUCKED!
First off, I’d like to say that I went into this knowing absolutely nothing about exhaust or how to install them so everything I say here is from someone with zero experience in this stuff so if thats you listen up. I’ll start with the good so you know that it far outweighed the bad. The sound is so nice. Loud when you push on it and quiet when cruise but not too quiet. They also look amazing compared to the stock muffler like 10x better. Ok now the bad, EVERYONE SAYING THAT IT TOOK THEM 2 HOURS IS EITHER A GOD OR THEYRE JUST STRAIGHT UP LYING! When I say it’s took longer than 2 hours I’m talkin like 8 to 9 hours! To be fair I stressed a little doing some stuff during and procrastinated a bit so it’s fair to knock off an hour or two for that but when I say it was way harder I mean it was literally impossible to do this without a saw. When I started this I enlisted my girlfriend To help so I wasn’t alone during this. The stock muffler it’s next near impossible to remove. After you finally find a way to remove the clamps you’re onto possibly the agonizing experience of my life and that is the hangers. DEAR GOD DO THEY SUCK! it took me maybe 2 hours to jack up the car and unbolt the clamps but those hangers I was sitting there trying to get off for what felt like an eternity. Just do yourself a favor and get someone to install them for you especially after you hear that sound and see how much you get for the money. All in all I’d rate my experience a 10/10 would try again. Thanks for coming to my ted talk!Helpful (1)

Roush axle back
Well worth it. Have had many compliments on how good it sounds. There is a little bit of a raspy tone around 3500 rpm but not a big deal. This exhaust is very true to the mustang sound and I highly recommend itHelpful (1)

Roush Axle-Back is awesome!
The exhaust was very easy to put on with the right tools. It feels like I’m driving a whole different car my vote is a 10/10Helpful (0)
Does this exhaust require a tune? Would it be more beneficial to update your tune specifically with these axle backs? Thanks
Axle-back exhausts do not require a tune. You can simply bolt them on and enjoy!
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.
Will this fit on a 2016 v6 mustang?
No, this axle-back will only work with 11-14 V6s. You would need this option for a 15-17 V6: https://www.americanmuscle.com/roush-axleback-1517v6.html
will this produce any drone to where you can not hear radio?
The Roush exhaust will generally produce very minimal drone.
These would not fit with your existing exhaust.
Unfortunately we do not currently offer an item that would reduce the cabin noise. With that being said, sound deadening panels for the interior are a good way to help with that.
No, the mufflers on the GT and V6 Roush axle-backs are not the same.
This would be the same just with polished tips.
They can be welded if you so choose, however that is not required for install.
These are not designed to be welded but can be if you wanted to.
While the sound will be altered being in an open-air environment this should still provide similar sound quality.
Roush does not release specific decibel ratings for their products. We recommend speaking directly with local ordinances regarding the drive-by noise legality.
