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.

      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.

      Vrooom!

      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.

      Review from Roush Axle-Back Exhaust (15-18 EcoBoost)

      Awesome sound

      Definitely gives the ecoboost the added "boost" of sound, and its fairly deep too. No heavy drone when at high speeds either.

      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.

      Loses Volume after Time

      Had this for about 2 years now and i noticed that its not as loud as when i first put it in. It also lost some of the exhaust tone. Definitely not worth $550. should cost $350 for what you are getting. It is better then most options for the v6 but you wont get much value out of it...

      Roush Vs Borla Atak

      I had a hard time deciding between a Roush or a Borla Atak. Watched every youtube video out there. I can say im glad i chose the Roush. If you still have a Stock v6 exhaust, This axle back will be perfect. Its exactly like how the youtube videos describe, Quiet when you want it to be, loud when you want it to be. Again, youtube sound clips arnt the best, Out of all of the sound clips i herd, it sounds x2 as better in person. Hope this helps someone out!

      Worth every cent

      This axle-back exhaust does exactly what it says! When you want to just cruise and leave it run it’ll be all calm, but once you step on it it’ll give you a whole new aggressive sound! I really thought about spending the money on this and I got to say it was worth every cent. On top of that, the installation was extremely easy. Simply cut the old mufflers out and clamp the new ones with a drill, that easy.

      Perfect balance!

      The Roush Axle-Back exhaust is the perfect balance of aggressive and passive! It gives off a nice growl when idling and cruising, but a nice roar when you step on the gas! It won't make your v6 sound like a v8 but it makes it sound respectable and better than a rice burner

      Excellent quality

      I'm not made of money, but I wanted a product that would give me a deeper growl and last a long time, so I wouldn't have to take it to the shop and have something fixed every five minutes. Looks good, sounds great at a good price.
