        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 2019 Ford Mustang EcoBoost Models without the Active Valve Exhaust.

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

        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.

        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.

        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.

          Sounds great

          Combined with a resonator delete y-pipe, gave me the sound I was looking for. Nice burble at idle and screams when opened up.

          Great add on with a great note

          The car stock sounds horrible. Wanted something to make it sound meaner without going over the top and after 6 months of looking i found the right one. This exhaust is a huge up grade on cold start and sounds great down the road. I have a convertible so i was worried of noise level. The reviews says it loud, it’s not. It can get up there but I like that it only does when you get it to 4-5000 rpm. The tome is more than I expected. I love it. Best $300 spent on this car. Took it to a shop and was in and out in 30 minutes

          Great upgrade for the price

          Looks fantastic, and for the price, I don't think there is a better value for a mid-range upgrade to the sound. It's not loud, but it's not quiet either, especially if you're on the throttle. Otherwise, it has a great deep tone sound.

          Great bang for your Buck

          I recently went big turbo with my Ecoboost and had an upgraded 3" down pipe installed, previous to the build I had gotten rid of the resonator and did a muffler delete and still had the OEM cat and the exhaust note was perfect for a pretty much straight pipe set up. After the install with a bigger downpipe and cat delete the exhaust note was way to loud and way raspy once you hit 3k RMP. After looking at all the different mufflers and differences in price I chose to go with Nxt step mufflers and I am so glad I did! exhaust note is perfect with that deep rumble and best part about it? NO MORE RASPY exhaust note. Quality of the mufflers themselves are beautiful with nice big 4" chrome tips that stand out and install was a piece of cake with a simple cut and clamp with no welding needed. Thanks AM with another great product!

          Great exhaust

          Give the ecoboost a great look with the polished chrome tips. It deepens the tone of the exhaust without it being super loud. Gives it a great, rich sound.

          Good Sound, Good Price

          I'll start with the positives for this review and disclose that I am running a stock system with the factory resonator and downpipe still in place. Firstly, if you are looking for an exhaust for your Ecoboost that isn't crazy loud or expensive, (but still reminds you and other folks that you are indeed driving a performance car) then this system should be near the top of your list. Nice, deep rumble upon start-up and continuous through idle RPMs. It doesn't blow you away with regular driving, but open the throttle and this thing will scream with lots of turbo noise. Very little to no drone at highway speeds, either. The price of this system is unbeatable for the sound and quality of parts, but where it fell apart for me was the installation. It wasn't hard to measure where to cut the factory mufflers (essentially right where the pipe straightens out behind), but getting the new mufflers in place was ridiculous. I had to beat these things to death with a rubber mallet to get them to hang and fit over the factory piping, which was way more exerting than this installation should have needed. The tips look fantastic, though, once I got them in place and secured. Overall, great purchase.

          Mustang just went from a Pony to a Stallion!

          The look of these exhaust is great. The chrome really stands out. In fact, I've never noticed the stock exhaust. When you get it installed, make sure to look at the difference with the new one installed and the stock still on on the other. They sound just exactly how I want it, and is even better when I am accelerating down the road. When you rev your car to a 3 when driving, you will start to feel it. It took about 45 minutes to install, and the guy did it for 60 bucks.Say the look is Great. The sound is exactly what you want and is even better when accelerating down the road. You can hear and feel it in the car, very nicely. Also that it took about 45 minutes to install and a professional did it for 60.00.

          Not as loud as they say

          The sounds is not as loud as the description says but it does have a deep tone to it to give it that mustang tone. Mechanic is ordering me a custom H pipe to make it louder.
