Construction & Design

This exhaust system is crafted primarily from T409 stainless steel, a value-focused alloy that offers the same aesthetic appeal as T304 stainless steel but with slightly reduced durability, making it well-suited for moderate climates with occasional exposure to moisture. The system’s tips are formed from premium T304 stainless steel, featuring a single wall construction with a rolled angle cut and a mirror-polished finish that resists corrosion and maintains a showroom shine.

The 4-inch tubing diameter is engineered to optimize exhaust gas flow, reducing backpressure and enhancing engine efficiency. The single side dual outlet layout not only improves exhaust scavenging but also adds an aggressive visual element to the rear of your Ram.
