Aggressive Raspy Sound. Let everyone know your V6 Mustang has arrived with the aggressive raspy sound of this high performance Roush exhaust. This innovative new Roush exhaust system features a hollow open 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 mandrel bent 304 stainless steel for a durable long life, the Roush axle-back exhaust system features two unique open chambered mufflers with 304 stainless steel 4" tips. The 4" tips are finished with a new chrome flashing process that is resistant to discoloration due to exhaust heat.

Cut & Clamp Installation. The installation of this Axle-Back Exhaust requires cutting and removing the stock muffler assemblies, and clamping the new muffler assemblies in place. Clamps and instructions are provided.

Can the stock exhaust go back on after having this on?

mustafa

  • Since this exhaust is a clamp on, you will be able to re-install the stock exhaust at a later point in time.

Will this effect factory warranty?

KyleW

  • Generally axle-backs would not void out the warranty. However each dealer has its own take on their warranty. We wold suggest double checking with the dealer who is offering you the warranty first.

Will the v6 axle back fit on the ecoboost? If not what is the difference between the two exhausts?

GrantK

  • This exhaust would be for the use of the V6 models only due to sizing however, we do have this exhaust for the EcoBoost models. https://www.americanmuscle.com/roush-axleback-1517eco.html

Does the installing of this product effect the gas mileage?

CaseyB

  • Hello! An axleback won't make any major changes in your gas mileage, some small gains, but when most people first get an exhaust mod on their car, they tend to give it a little more gas, and because of that you may see a slight loss in MPG at first!

    This is an amazing exhaust! Took it to a local shop and they installed it in less than an hour and, wow, does it sound incredible. When I hit the gas it has that deep note that I wanted, but when I'm at cruising speed I don't even know it's back there, which is nice. Sounds great and looks aggressive. Definitely the best mod I've done on my mustang so far!

    Great sounding exhaust

    Very happy with this exhaust. I have tried the ATAK and the Roush, and both were great exhausts, but I prefer the Roush. The ATAK screamed where the Roush roars. The ATAK was over-the-top loud but the Roush was a bit more mild in volume. The ATAK honked out an annoying note around 2700rpm, which the Roush is smooth throughout the entire range. I do prefer the weight and smaller profile of the Roush. Sounds great through tunnels. It's less raspy than the ATAK on revs, but still has some nice pops and gurgles. Cruising is much more quieter with the Roush, which makes phone calls through SYNC easier. If you want your car to be obnoxious and over-the-top you won't be disappointed with the ATAK as it was definitely a fun addition, but if you want something that can be quiet or roar depending on your mood, go with the Roush. If you have a CAI installed, the Roush seems to compliment the rumble of the CAI instead of drown it out.

    Excellent sound and easy installing

    It took me and my workmate less than 1 hour to cut and install it. We all feel it is easier than we expect. The sound is so great and different compare to the original one. It gives the V6 mustang the sound it should have. More people on the road notice and like my car. The muffler won't influence the smog check, right?

    2 Words: Oh Yes

    Of the mods I've done so far, this was by far the biggest bang for my buck. The Roush axle-back system gives my V6 the sound it should have had from the factory. 2 shiny Roush-embossed tips give way to the sweet burble. I'm loving it! Fitment was perfect though I opted to have them welded on versus clamp-fitted. Easy install - less than 20 minutes at my local shop.

    No regrets

    These axle Back exhaust Are great,I was worried when I ordered them cause I didn't want them to be to loud cause of neighbors ,took them to local muffler shop and they installed it in 45 minutes for great price $100, I love the sound..I kept everything else stock only running the Roush AB.. idle is much deeper it's quite at cruise but screams when you hit gas... I got v6 and the stock exhaust was embarrassing but now it's how it should be... 2 thumbs up

    Took a friend and myself about 30 minutes to install! Used car ramps. View the video from CJ on YouTube , very helpful. It sounds great! Low rumble at idle, and at low cruising speeds. It really compliments my Roush CAI.

    Perfect upgrade for the daily driver

    Love the sound! No drone what so ever. Adds the right amount of aggressive sound without sacrificing comfort. Phone calls still sound crystal clear on both sides unless you step on it. It sounds really good when you get on it in between gears. Because it was a cut to install, it put me back an additional $120. The guy was able to do it in roughly 45 minutes.

    Easy install, aggressive V6 sound.

    Install was really easy with the right tools, less than an hour. Cut, install, clamp, done. These are loud and aggressive when you want, quiet when you don't. Gives the car a mean V6 sound, not a V8 wannabe sound.

    Good for a V6

    Definitely doesn't sound like a v8 (probably because it isn't' a v8) but still sounds pretty good. There is a deep growl sound to it when you get on it with some popping on deceleration. It isn't very loud at all at idle and cold starts but you can definitely tell its there. Worth the purchase if you're not gonna go with a cat-back.

    Excellent Exhaust - Highest quality

    Very pleased with this exhaust, has an aggressive tone, but not overly loud on the highway, well done. Certainly opens up when you get on the throttle. My daughter and I installed the unit in about 1 hour (on her Mustang). I fairly straight forward install and the instructions (online at Roush are pretty much a "1 pager". Highly recommend!

    The soundtrack that always should have been

    First and foremost, this exhaust is loud, borderline wake the neighborhood loud. That being said the noise is a soundtrack strait out of a movie that the V6 should have had all along. Again, though the sound is droneless, it's not the quietest on the interstate, though this is me being picky than an actual issue. With a fantastic growl throughout the rev range and a sharp crackle while decelerating, if you are looking to get the aggressive sound the V6 needs, look no further. Looking for something that won't wake the neighbors and be quieter on the highway, keep looking.
