Product Description

Roush Axle-Back Exhaust Kit
Give your 2011-14 5.0L Mustang the wild howl of American V8 muscle that it deserves. This innovative new exhaust system from ROUSH features a hollow muffler chamber, as opposed to conventional fiberglass-packing. The result is a unique and less inhibited sound, increased air flow, and increased longevity (there is no fiberglass that will break-down with time). Another great feature of this system is the lack of the in-cockpit boom normally found with performance exhaust systems at cruising speeds.

Roush Quality
Not only does this exhaust sound good, it looks good as well. The round tips are made from high-quality 304 stainless steel and are finished with a chrome flashing process. Conventional chrome plating uses layers of bonded chemicals to achieve its shiny appearance, which are susceptible to cracking and flaking especially when exposed to high temperatures (like exhaust). However, the chrome flashing used in this system is bonded micro-porously to the metal surface, and is as a result impervious to cracking from localized damage. This method of chroming is also resistant to heat color change.

Installation
As you would expect, the installation of this system is quick and easy. The exhaust uses the factory hanger mountings, so you don't have to fabricate your own. This kit also features new OE-quality spherical clamps for a better fit.

Application
- Fits 2011-2014 Ford Mustang GT & GT500

    5 Stars   Music to my ears!!
    By on 3/11/2014
    Ordered this exhaust for my 14' GT/CS on a Wednesday afternoon and received it in the mail less than 24hrs later! Got it installed in about 25 minutes using a lift and the fitment was spot on. First cold startup and your welcomed with the sweet sound of horsepower music. Just flat out heavenly. Ahhhh.... Once the car warms up, you're left with a nice low and throaty idle. Step on the gas a little and you're fed a rich muscle car tone with a sprinkle of that notorious mustang sound. Beautiful. And then there's the WOT.... bliss, just bliss. Its how a mustang should sound. Overall, very pleased with this axleback, it has a great fit and finish, superb sound, and a fair price. Hats off to Roush.

    Bought this axle back a few weeks ago to wake up the sound of the boss 302. Definitely worth it. Some mention that it is "raspy" but I didn't experience that with side pipes fully open. Very little drone, loud as hell when you get on it, and quiet when just cruising. What's not to like?

    Image uploaded by Christian W. Finished this install in my garage with my dad in 28 minutes just by backing it up on ramps... Never took off the H pipe though I did loosen the pipes so id have better space to move about (let the pipes move back n forth) Out of everything out there I believe this is hands down the best axle back setup you can go with on the 2011 5.0, im sure just an x-pipe next will increase the volume miles, but for now this is how im keeping it till im used to it, its very loud for just a muffler swap. Makes you wander how ford got away with restricting the car so much. Latemodelrestoration had this at my door the next day at 3pm. I ordered the day before at 11am, almost like picking it up at a store its unbelievably fast. ps Alot of people arent going to want there car any louder than this, already got neighbor complaints ie too loud.... But its quiet as can be if you can stay off the throttle. No drone.

    5 Stars   Roush Exhaust For The Wim!
    By on 12/21/2014
    I just installed my Roush exhaust today on my '14 GT. First, I was pleasantly surprised on how smaller and lighter the Roush exhaust is compared to stock. Second, the quality of this exhaust is very hard to beat for the price. Third, very easy to install with great fit.
    The sound is deep and throaty. It has minimal drone when cruising. Remember, I said "minimal" and not "absent". The sound that comes out when you romp on the go pedal is absolutely music to my ears as it is to so many that have this exhaust. Yes, I highly recommend the Roush exhaust for your Coyote!

    I was so anxious and excited at the same time, so when I ordered these roush exhaust and they finally came in "wow"I felt like a little kid .When I finally install them they surpass my expectations, really that roar when you first start your car and that aggressive sound when you take off. But at the same time that nice pleasant sound when you're idling. Great job Roush!

    I sat on the fence for about 6 months on which axle-back to buy. I was looking at Flowmaster, Bassani, Borla and Roush as my final selection set and ultimately went with this Roush kit based on the price point, lack of drone and fit/finish.

    All said and done the install took less than an hour. Pro tip: put jack stands under the rear axle and use your floor jack to lift the mid-pipe (over axle section) to allow clearance while you remove the stockers and position the Roush kit. It took me about 15 minutes of wrestling with the spacing before I realized this little cheat.

    Fit and finish are beautiful, weight saving is huge and the sound is outstanding. Cold starts are a thing of beauty, cruising speed is barely louder than stock but get on the gas and you are instantly transported back to being 16 years old with a huge shit eating grin on your face.

    Enjoy!

    After a long...long time trying to decide what axle back to go with I finally went with Roush and I was not disappointed. Yea there are louder models out there but I wanted something that I could drive with on the daily and not have to yell at passengers. It's quite when your just doing your normal driving but when you open it up you know I'm coming. Instal note follow the instructions or watch a video online and basic knowledge will get the job done, however make sure that your vapor hose line is not near the axle back just tie it up somewhere safe or it might melt and then you have a annoyance everytime you go to fill up and you can only get 2 gallons in before it auto shuts off lol $28 later new hose and problem fixed

    5 Stars   great exhaust
    By on 5/28/2015
    my decision came down to either the roush or the borla exhaust and at the end of the day i just could not bring myself to shell out 8 or $900.00 for axel back exhaust.
    ordered the roush from late model restoration and recieved it the next day. packaged very well and when i opened the box i was impressed with the quality of the components and i try to buy american made products whenever possible.
    this exhaust is just what i was hoping for a nice growl under power and 4000 rpm and above it just screams,but just cruising at highway speeds it quiets down nicely with no drone.

    By on 1/4/2016
    Before even purchasing my 2014 GT, I watched tons of videos of the Roush Axle back among other axle back exhausts.
    I was immediately sold on this one. Perfect fitment and I love the adjustability of the tips.
    As far as sound, it is a great improvement over the stock sounding much less restricted. Plenty loud when you get on the throttle, but also very quiet when you want to cruise as high or low speeds; not ruining anyone's day.
    Roush makes an incredible product!

    Shipping was fast. I received my order in three days and it was over a weekend. Install was a breeze. Removing my stock axle backs was a challenge due to doing it on ramps instead of jack stands. I found that completely removing the hanger eliminated the need to slide the mid pipes forward. These Roush axle backs are the best sounding exhaust I've heard for the 11-14 S197. Great product! I highly recommend.

    Luckily I am local I was able to pick this up from the LMR office. Great guys there and I will not order from any other place going forward. Quick and easy install. A bit quieter than muffler deletes but with that same growl. These have no drone, which was my main issue with the deletes.

    By on 4/8/2015
    I ordered this product and then the next day I received a call from someone at LMR inquiring about the order. They left a voicemail and number which I promptly returned 30 minutes later. No answer. Left a voicemail, called again an hour later. No answer. Called another number for my "local representative" 3 hours later. No answer. Sent an email to which I still have not gotten a response. Finally this morning after being on hold for 15 minutes, I got through. They needed verification of my shipping address via water bill or cable bill (seriously?) and refused to ship to anywhere other than my billing address. Although I called and confirmed my address they will still not ship my parts that I've already paid $500 for. My friend JUST ORDERED PARTS AND HAD THEM SHIPPED TO MY HOUSE LAST MONTH. He has no affiliation with my house whatsoever. Are you reading this LMR?

    Anyway now I'm getting parts late and one hour away from where I currently live because I'm not in a permanent residence and the land lord's name is on the bills, not my name. Last time I order from these goons.
