This American Thunder exhaust system is individually engineered and dyno tested with the latest in exhaust technology. Through this technology you will experience improvements in acceleration, passing power, fuel economy, and sound. The key to this system's performance improvement is through the use of mandrel-bent tubing and a 2-chamber muffler(s) that allow for superior exhaust flow with a deep, low, aggressive tone. All components are manufactured from aluminized steel tubing for corrosion-resistance and long-lasting good looks. This kit includes all hangers, clamps, and mounting hardware for an easy installation.
