aFe MACHForce XP SS DPF-Back Exhaust

2011–2018 Ram 1500 3.0L EcoDiesel V6

Part #: 49-42041-B

Overview

The aFe MACHForce XP Stainless Steel DPF-Back Exhaust system is a precision-engineered upgrade designed specifically for the Ram 1500 equipped with the 3.0L EcoDiesel V6 engine from 2011 through 2018. This exhaust system replaces the restrictive factory setup from the Diesel Particulate Filter (DPF) back, improving exhaust flow and reducing backpressure to unlock enhanced horsepower, torque, and overall engine efficiency.

Ideal for diesel truck owners who demand durable, high-performance components, the MACHForce XP exhaust delivers a refined aggressive sound and a sleek black stainless steel tip that elevates the truck’s rear appearance. It is engineered to withstand the rigors of daily driving, towing, and heavy-duty use while maintaining reliability and longevity.

Key Features

Combining advanced design with premium materials, the aFe MACHForce XP exhaust system offers the following key features:

• Mandrel-bent 4-inch 409 stainless steel tubing for maximum exhaust flow and long-lasting durability
• Large bore 2-1/2 inch DPF-back design optimized specifically for the 3.0L EcoDiesel engine
• High-flow muffler engineered to reduce exhaust restriction while delivering a smooth, deep exhaust tone
• Bayonet-style hangers for quick, hassle-free installation with no modifications required
• Polished stainless steel exhaust tip with a durable black finish for a modern, aggressive look
• Precision-engineered smooth transition bends to minimize turbulence and maximize power output
• Corrosion-resistant 409 stainless steel construction for long-lasting performance in all weather conditions

Construction & Design

The MACHForce XP exhaust system is crafted from premium 409 stainless steel, known for its excellent corrosion resistance and strength, ensuring durability in harsh environments. The mandrel-bent tubing maintains a consistent diameter through every bend, preventing flow restrictions caused by kinks or sharp turns and preserving optimal exhaust velocity.

Each component is precision-fabricated to fit the Ram 1500 EcoDiesel chassis perfectly. The bayonet-style hangers align with factory mounting points, allowing for a secure, rattle-free installation without the need for cutting or welding. The polished stainless steel tip features a black finish that resists fading and adds a distinctive visual upgrade to the truck’s rear.

Performance & Sound

By reducing exhaust backpressure and improving flow efficiency, this DPF-back exhaust system enhances horsepower and torque output, resulting in improved towing capability and throttle response. The high-flow muffler balances performance gains with a refined exhaust note, delivering a deeper, more aggressive sound without excessive drone or harshness inside the cabin.

Additionally, the optimized design helps lower exhaust gas temperatures (EGTs), which can contribute to better engine reliability and efficiency during heavy-duty operation or extended highway driving.

Installation & Fitment

The aFe MACHForce XP exhaust system is designed for a direct bolt-on installation with no cutting, welding, or modifications required. Bayonet-style hangers align precisely with factory mounting points, allowing for a straightforward swap with the stock exhaust system. Professional installation is recommended to ensure proper fitment and optimal performance.
