Stainless Steel Axle-Back Exhaust with 4-Inch Dual-Walled Tips

The NXT Step Performance axle-back exhaust system is engineered to upgrade the exhaust flow and tone of 2011-2014 Ford Mustang GT and 2012-2013 Ford Mustang Boss 302 vehicles equipped with the 5.0L V8 engine. It is constructed from high-polished, mandrel-bent stainless steel piping and includes quad, 4-inch dual-walled T304 stainless steel tips. Installation is a bolt-on process that utilizes the vehicle's original mounting points; however, this system requires the use of OEM clamps. Professional installation is often recommended to ensure correct alignment and clearance. Please note that users should not use air impact tools to tighten fasteners, as doing so may cause damage to flanges or gasket areas. After installation, any smoke or fumes observed are typically due to the protective oil-based coating used in manufacturing and will dissipate once the exhaust reaches normal operating temperatures. This system is 50-state emission legal. It is important to verify compatibility, as this specific part is designed for the 5.0L V8 Mustang models listed; it is not compatible with V6 or other non-specified engine configurations.
