Description
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 .
Cut and Clamp Installation. The installation of this NXT Step Performance Axle-Back Exhaust system will require cutting and removing the stock muffler assemblies. The new muffler assemblies will install in place of the old. Clamps and instructions are provided.
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 2023 Ford Mustang EcoBoost Models without the Active Valve Exhaust.
