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 mandrel-bent tubing maintains consistent diameter throughout bends, reducing turbulence and backpressure to maximize exhaust flow efficiency. This construction ensures long-lasting durability even under demanding diesel truck operating conditions.

The system includes a black stainless steel clamp-on exhaust tip measuring 7 inches in diameter, which adds a refined yet aggressive visual accent to the rear of your Ram truck. The use of OE-style hangers and flanges guarantees a factory-like fitment and secure mounting, preventing leaks and rattles over time.

Performance & Sound

By minimizing exhaust restrictions, the aFe ATLAS system improves engine breathing, which can contribute to enhanced throttle response and overall performance. The 5-inch diameter tubing allows exhaust gases to exit more freely compared to stock systems, supporting better turbo efficiency and potentially aiding in power gains.

The exhaust note is tuned to deliver a deep, aggressive tone that enhances the commanding presence of your Ram 2500 or 3500 diesel truck without being overly loud or droning during highway cruising. This balanced sound profile appeals to diesel enthusiasts who want a performance sound upgrade that remains comfortable for daily driving.

Installation & Fitment

The ATLAS exhaust system is designed as a direct bolt-on replacement for the factory exhaust on 2019–2026 Ram 2500 and 3500 trucks with the 6.7L diesel engine. Installation requires no cutting, welding, or modifications, making it a straightforward upgrade that can be completed with basic hand tools. The system uses all factory mounting locations and hardware styles, ensuring a secure and leak-free fitment that maintains factory alignment and ground clearance.
