    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.

    Application. This Roush Performance Axle-Back exhaust system is designed to fit the 2015-2017 V6 Mustangs for both great looks and great sound.

      Review from Roush Axle-Back Exhaust (15-19 EcoBoost w/o Active Exhaust)

      Must get

      After searching for about a month reading up/watching countless hours of videos on almost every option of exhaust systems for the eco, I came to this. Hesitant of ending up with a ricer sound out of the 4 cylinder, you get the complete opposite. I could not be happier with my choice. If I was faced with the decision over again, I would definitely go with this 10/10.

      This roush exhaust gave my somewhat quiet EcoBoost the sound she was needing definitely woke her up. I now have it paired with a bbk catted down pipe and sounds even better!

      Great exhaust , but

      Love the sound, However, the drone at low RPMs in higher gears between 1500 and 2000 RPM is horrible. I would say it is the equivalent of sinning on a twin engine prop plane between the motors . Running the car is sport mode eliminates this because it keeps the rps up.

      Review from Roush Axle-Back Exhaust (15-19 EcoBoost w/o Active Exhaust)

      Amazing

      The videos do not do it justice. It pops and bangs during launch control and will backfire like crazy. Really quite at low rpm so you won’t wake your neighbors up but put your foot to the floor and it comes to life. Great price, looks great, and installation was simple.

      Just a 6

      One of the quickest best sounding exhaust systems for a v6 mustang. When it's cold, it pops. When you let off the gas, it pops. When you hit it, it screams. Very impressed. Louder than expected

      Fantastic way to get a throaty exhaust note

      Ordered and installed this myself, incredibly easy for even first timers. Very happy with the sound that comes with it. part of me wishes I had gotten the full Roush Cat-Back exhaust, since i think they use these with that kit. But overall, I am very happy with my purchase!

      Solid exhaust note!

      Purchased this muffler set about a week ago and received it very quickly. I took it to a muffler shop to get installed because I live at an apartment complex and don't have the necessary tools, otherwise I would've tried the install myself. Anyways, the exhaust note is absolutely perfect. Deep and throaty when on the pedal, low and relatively quiet when idling. At low RPMs, you can creep along, but punch it and let those RPMs climb and it sounds like a mean son of a gun. It really makes the car feel alive and gives it the sound to go along with the performance of the V6. I definitely recommend this upgrade.

      Good buy

      Gives your v6 a buffer sound but not high enough to turn heads. Keeps me off the cops radar. This exhaust is good for those who have a show car instead of a race car. I like it.

      2017 Mustang ECO

      if your looking for an exhaust that’s incredibly loud and quiet at the same time this is so the one. Once the turbo is workin hard and when you have the pedal down 1/4 -1/2 it screams. Its awesome quality, the tips are beautiful. So happy with it.

      roush axle back

      Product is awesome and definitely gives your car a deeper tone but i had to remove my resanators to really make it sound deep enough to hear with the ecoboost. Rated a 4/5 because for a 600 dollar performance muffler i shouldn’t have to delete my resanators to get better sound but still a great product and i do recommend if you’re going for a subtle nice sound.

      Roush axle back with my bbk headers

      This product gives your v6 and v8 the best sound. Is more aggressive when u hit the throttle and it very quiet when idle. Add this to my bbk shorties and my v6 sounds amazingly perfect and deep.

      The Roush axle-back exhaust is as advertised; great sounding exhaust note. There appear to be a slight drone at highway speed, but not at all bad.

      Best decision I've made

      Anyone looking to make their V6 sound like a real mustang,this is a great upgrade. Not obnoxiously loud, but loud. I also recommend getting the muffler cutters if doing the install your self rather than usinh a saw zaw.
