    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.

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 2018 Ford Mustang EcoBoost Models.

    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.

      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.
