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 the Roush Axle-Back fit the V6 convertible? The convertible has extra bracing.

Hi! I just ordered this exhaust along with the Flowmaster Scavenger Series Cut and Clamp Resonator Delete Y-Pipe (Item 389694) for my 2016 Ecoboost, and I read that they will fit fine together but I was just making sure before I tried to get them installed. Thanks!

    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

    Worth the Price

    When I bought this axle-back, I was looking for an exhaust that was going to add an impressive deeper "roar" that was more respectful over something loud and flamboyant. I'm a daily commuter (50 miles daily), driving almost always on the highway. This exhaust has a small drone initially, but you quickly get used to it. Around 2 RPM , you'll definitely hear it in the acceleration, but it isn't annoying or sounds cheap. Sounds like a high performing sports car. Remote-Start sounds 10x better. this was definitely a great buy for me. Friend of mine is an engineer and put this on for me in about 90 minutes.

    Not The Sound I Wanted

    I thought I would try Roush since reading the good reviews except for a couple of bad ones. I had flowmasters before on my other mustangs and wish I had bought them instead of these. To me I would have to agree with some others it makes my v-6 mustang sound like a rice burner. Next time I will know better

    Brings the engine to life audibly, not obnoxious, just enough to let others know you are there.

    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.
