Description

These stainless steel Force II exhaust systems have been designed with the latest exhaust technology available. Through this technology, you will experience improvements in acceleration, passing power, and fuel mileage. The key to these performance improvements is the use of mandrel-bent tubing. The tubing allows for superior exhaust gas flow, while stainless steel construction has been utilized for its corrosion-resistant qualities.
