Construction & Design

The ATLAS exhaust system is crafted from 5-inch aluminized steel tubing, chosen for its excellent balance of strength, corrosion resistance, and heat tolerance. The tubing is mandrel-bent to maintain consistent diameter throughout bends, minimizing flow restrictions and turbulence. This design ensures maximum exhaust scavenging and efficiency.

The system includes a polished stainless steel exhaust tip that not only enhances the visual appeal but also resists rust and discoloration. All mounting hardware, including hangers, clamps, and flanges, are designed to match OEM specifications, providing a precise fit and reliable sealing to prevent leaks.

Performance & Sound

By reducing exhaust backpressure and improving flow dynamics, the aFe ATLAS exhaust system helps your 6.7L Cummins diesel engine breathe more freely. This can translate into improved throttle response and a more efficient combustion process. The system’s design also produces a deep, aggressive exhaust note that enhances the driving experience without being overly loud or droning during highway cruising.
