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.

Decent purchase but not the best sound!
I had higher expectations for the sound thought it was going to sound like the one in the video but sounds like a stock muffler but with a deeper tone.Helpful (0)

Great tone w/ resi delete!
Very impressed with the sound. Paired with my Roush Y-Pipe it sounds deep in idle and has a good punch when pulling through the gears. Be ready for some noise, but not much in idle. I highly recommend these!Helpful (0)

Great Value for your money
I would say the sound is just right for me, not too loud but definitely change the stock exhaust sound and it sounds more aggressive now like a mustang should be like!!!Helpful (0)

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.Helpful (0)

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 alsoHelpful (4)

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 hourHelpful (2)
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.
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 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.
Yes, this will work with your vehicle.
Changing the mufflers on any care can run the possibility of increasing in-cabin drone but this system has not had reports of cabin drone that would lead to interior rattles.
This muffler will create some popping noises at times yes.
Both exhausts will be very similar in terms of the overall exhaust sound.
Please contact us to get ETA's on products.
The active exhaust allows you to customize the volume of the exhaust to an extent.
The price shown is for the left and right muffler assemblies.
