    Throaty Rumble Tone. NXT Step Performance Axle-Back Exhaust features a wide and free-flowing tube design that enhances air flow thus delivering a booming exhaust growl. The chambered muffler makes the sound even more intimidating. The unmistakable boxter sound produced by the exhaust kit similarly makes it suitable for racing applications.

    Better Performance. By enhancing exhaust flow, the kit significantly boosts your EcoBoost’s rear torque and horsepower. It gives you an average of 15-20 extra HP. It is also designed to remarkably boost your Mustang’s turbo response thus giving you a better RPM. You are also assured of better fuel economy since the kit lowers exhaust temperatures thus increasing engine power. Since the kit doesn’t contain components that may burn out with continued use, the performance gains will be maintained for ages.

    High-Grade Construction. NXT Step Performance Axle-Back Exhaust is fashioned from industrial-grade mandrel bent 304 stainless steel that is corrosion and rust resistant for superior strength. Its pipes are similarly made from lightweight stainless steel. The entire kit is coated with a stainless steel finish to enhance its looks and durability. What’s more, the finish is scratch resistant, and gives the Axle Back Exhaust a phenomenal appearance .

    Bolt-On Installation. NXT Step Performance Axle-Back Exhaust is compatible with your Mustang’s OEM clamps. It’s slip-on design means that you can install it without making modifications to your EcoBoost. Only basic hand tools are needed.

    Warranty. The kit is backed by a limited lifetime warranty against structural defects after inspection.

    Application. NXT Step Performance Axle-Back Exhaust fits all 2015 to 2020 Ford Mustang EcoBoost Models without the Active Valve Exhaust.

        5 Top Rated Questions

        I have a 2016 Ecoboost stock exhaust was looking at these axle backs but am concerned about the drone I drive pretty much all highway 75mph plus. Will it be very loud in the cabin? Or would you recommend another axxle back ?

        • Since the NXT Axle-Back Exhaust utilizes a muffler system, this will eliminate most drone created by those exhausts that are fully straight piped. This exhaust produces almost no drone when cruising at highway speeds.

        The title of the product says Axle-Back Exhaust (15-19 EcoBoost w/o Active Exhaust) and does not mention any brand name. The video mentions Nxt Step Performance mufflers. So are both products same?

        • This exhaust is made by NXT Step Performance.

        Will this fit with the FlowMaster Y-Pipe that is also sold on the website?

        • The Nxt Step Performance Axle-Back Exhaust will be compatible with the Flowmaster Y-Pipe.

        Will the computer need to be re-flashed or will any computer resetting be required if this system is installed? I am wondering how it affects the pressure in the exhaust. Thank you.

        • You would not need a tune with this axle-back exhaust and would have little effect on the back pressure of the system.

        Is this compatible with a 2016 Ecoboost Convertible and if so does it require cutting the stock exhaust? Can the stock exhaust be ever put back on?

        • This Nxt Step Performance Axle-Back Exhaust will fit with on a convertible and the factory exhaust must be cut. The stock exhaust could be put back on with a clamp, but it will not fit exactly as it did before.

            Love the sound

            It sounds way better than stock while still sounding slightly like it’s not after market. It gives the ecobeast a nice rumble that’s not too aggressive. I love it.

            gave my ecoboost exactly what it needed

            I listened to every exhaust made on you tube and finally decided on Nxt Step Performance axle-back. I had them installed at a performance shop for 90 dollars. Took 45 mins. The tone is deep and the sound is mellow. Not obnoxious like a japan made tuner. It has some drone but its not overbearing.Just Perfect. These are the best value on the market. Look Great also

            Plesently suprised

            The sound clips really don't do this system justice. It has a great exhaust note even for a four cylinder. Not hearing any drone either. I may be mistaken but I swear I feel a little more power. All in all very pleased. Install took my son a little over an hour

            Great Exhaust

            I was very happy with the quality and construction of the mufflers. Easy to install using jack stands and a floor jack, lift not required. Exhaust is louder but not excessively loud with a deep tone. It WILL NOT make your Mustang sound like a Honda. I have this exhaust paired with a resonator delete pipe, the turbo spools up much quicker. A great upgrade for a very reasonable price.

            Excellent low cost high quality axle back

            This axle back seems to be high quality. The stainless steel shines and looks great. It took less than an hour to install on car ramps. Sounds is not that of a V8 but my Mustang sounds great with it for what it is...

            Axle Backs

            I wanted a little louder than stock sound for my 2016 Ecoboost Premium. Also, I didn't want to spend a ton of money on mods, just because I've been there done that. Local muffler shop said it would sound like a hi speed bumble bee, so that scared me a little. Let's be real, it's not a V-8 and not gonna sound like one, but it is not an obnoxious "Honda Tuner" sound either. Just enough of a little rumble and the quality of the polished SS is really nice to look at. Wifey approves of the look and sound too. At least the tips are nicer than stock as well. I recommend these as $320 bucks was a deal.

            Looks nice and Sounds nice!

            I wanted to upgrade my exhaust to something a little louder and deeper than stock - this exhaust was perfect. My Mustang sounds a lot better now and it's not too loud. It sounds stock when you're a cruising speed. It really kicks in when you're in the lower gears which is what I wanted.

            Why spend more?

            I looked at all the other reviews and listened to the video sample and pulled the trigger. This axle-back provides just the right amount of rumble without being overbearing. The item arrived in beautiful condition and I was able to get it professionally installed in less than an hour. The difference was noticeable immediately. The car now has a nice satisfying baritone exhaust note. In no way will this make your EcoBoost sound like a 5.0. but it will indeed lower the register and up the volume a bit so that you can actually hear the exhaust. It's not too loud to be annoying or illegal, but does give, IMHO, just the right amount of grunt. For convertibles like mine, that can't install a full catback kit due to the bracing in the undercarriage, this is the next best thing.

            Holy smokes the Pops!!!

            This exhaust is incredible for the price. It was very easy to install, i could feel a bit of power gain, and the best part is how loud and agressive it sounds. I know that the higher price of an exhaust the better it is, but the sound and quality is great of these new axle backs. I recommend these 100.

            Value for money product

            If you are looking for cheapest option, this one is the best deal. sound is okay. I would say loudness is 2 on the scale of 1 to 5, 5 being the loudest. Easy to install. I had local body shop install is for me for for 90 bucks. All you need is someone who can lift the car and cut the existing exhausts. I would rate this product 4 on 5.

            PERFECT!!

            The tone is perfect and the video's posted here dpo not do it justis at all. When they make the recordings it's too close to the camera and the audio gets somewhat distorted. The tone is perfect, loudness is perfect and overall quality it A bar none. Drone is next to nothing and the fit was perfect. The install took me under 30 min start to finish (including putting the rear on jack stands). If you're thinking about getting this system, pull the trigger you won't be sorry. I was looking for a system that was not to loud, virtually no drone and great quality. BEST BANG FOR THE BUCK HANDS DOWN. Can't say enough about this system. Buy it!!
