The MagnaFlow Street Series 15899 brings enhanced engine sound and dyno-proven performance to your muscle car with a healthy helping of our deep, resonant signature exhaust note at Agressive exterior and Moderate interior sound levels. Thanks to its durable, corrosion resistant stainless steel design, this exhaust system will handle whatever tarmac you decide to leave your mark on. This performance exhaust kit features a crossmember-back layout designed to replace your exhaust system from the crossmember on back. With its fast-flowing, mandrel bent 3in. main piping and 2 Straight-Through mufflers ending in a Dual Split Rear exit that you can enhance with tips of your choosing, your muscle car will be sounding as awesome as it looks. Extensive 3D scanning during development has resulted in a direct-fit design that you can easily install yourself. 15899 is produced using CNC precision robotic manufacturing techniques and is backed by MagnaFlow’s limited lifetime construction warranty.
