Construction & Design

The MACHForce XP exhaust is crafted from corrosion-resistant 409 stainless steel tubing, known for its strength and ability to withstand high heat environments common in diesel applications. The tubing is mandrel bent to maintain a consistent diameter through bends, ensuring unrestricted exhaust flow and optimal performance gains. This precision bending reduces turbulence and backpressure, allowing the engine to breathe more efficiently.

OE-style bayonet hangers securely hold the exhaust system in place, minimizing movement and wear caused by vibration and heat cycles. The dual 6-inch black powdercoat tips not only provide a striking visual upgrade but also resist corrosion and fading, maintaining their aggressive look over time. Factory-style flanges and band clamps ensure a tight, leak-free seal, contributing to the system’s durability and reliability.

Performance & Sound

This DPF-back exhaust system is engineered to improve horsepower and torque by enhancing exhaust flow and reducing backpressure. The free-flowing muffler absorbs unwanted high-frequency tones, delivering a deep, aggressive exhaust note that enhances the driving experience without excessive drone. By unlocking the full potential of the Ram 1500’s EcoDiesel engine, the MACHForce XP exhaust provides a commanding sound that matches its performance capabilities.
