Construction & Design

This exhaust system is crafted from premium 409 stainless steel, chosen for its excellent resistance to corrosion and ability to withstand high temperatures typical of diesel exhaust systems. The entire system is finished with a high-temperature satin black powder coat that protects against rust and wear while providing a sleek, aggressive look that complements the rugged styling of Dodge Ram trucks.

Mandrel bending technology ensures the 4-inch diameter piping maintains a smooth, unrestricted flow path, minimizing turbulence and maximizing performance gains. The dual single exit design is strategically located behind the passenger side rear tire, offering a distinctive appearance without compromising ground clearance or vehicle balance.
