The addition of a Corsa axle-back exhaust system will boost horsepower and make a serious improvement in the sound department. Corsa flow bench tested their axle-back, showing a 61-1/2 percent gain in exhaust flow versus the stock exhaust. Straight through 2-1/2" nonrestrictive tubing is designed to maximize airflow, improving both performance and fuel economy. Premium grade 304 stainless steel components ensure the look and sound of your Corsa exhaust won't change over the life of your vehicle. Although the axle-back's construction is much more durable, it is still ten pounds lighter than the factory axle-back. 4" Pro Series exhaust tips are painted black for a stealthy look. The Corsa axle-back is 50-state emissions legal.
