aFe Twisted Steel Shorty Headers

2009–2016 Dodge Ram 1500 & 2009–2018 Dodge Ram 1500 5.7L Hemi

Part #: 48-42001-1

Overview

The aFe Twisted Steel Shorty Headers are engineered specifically for Dodge Ram 1500 trucks equipped with the 5.7L Hemi engine from 2009 through 2018 (with fitment covering 2009–2016 and 2009–2018 model years). Designed to replace your factory exhaust manifolds, these shorty headers provide a direct bolt-on upgrade that enhances exhaust flow and engine performance without the need for cutting or drilling. Ideal for enthusiasts seeking improved horsepower, torque, and throttle response, these headers maintain compatibility with your stock catalytic converters for a hassle-free installation experience.

Built to deliver reliable performance and durability, the aFe Twisted Steel Shorty Headers optimize exhaust scavenging and reduce flow restrictions, making them a smart upgrade for daily drivers and performance-minded Ram owners alike.

Key Features

These headers incorporate advanced design elements and high-quality materials to maximize performance and longevity:

• Constructed from 16-gauge 409 stainless steel for excellent corrosion resistance and strength
• Mandrel-bent 1-5/8" tubing ensures smooth, unrestricted exhaust flow
• 4-to-1 mitered merge collectors reduce turbulence and increase exhaust velocity
• Optimized tube lengths utilize true pulse control technology to enhance flow and power delivery
• 100% hand MIG welded for superior structural integrity and durability
• Heavy-duty 3/8" thick one-piece flanges prevent warpage and ensure a leak-free seal
• Direct bolt-on installation using factory mounting locations—no cutting or drilling required
• Compatible with both 2WD and 4WD Ram 1500 models

Construction & Design

The aFe Twisted Steel Shorty Headers are crafted from premium 16-gauge 409 stainless steel, chosen for its balance of durability and resistance to heat and corrosion. Each tube is mandrel-bent to maintain consistent diameter and smooth bends, minimizing flow restrictions and turbulence. The 4-to-1 mitered merge collectors are precision-engineered to eliminate flow-block turbulence commonly found in formed collectors, resulting in improved exhaust scavenging and velocity.

Every header is hand MIG welded by skilled technicians to ensure optimal strength and long-lasting performance. The thick, one-piece flanges provide a robust sealing surface that resists warping over time, preventing exhaust leaks and maintaining performance integrity throughout the life of the vehicle.

Performance & Sound

By replacing restrictive factory manifolds with these shorty headers, you can expect noticeable gains in horsepower and torque, along with sharper throttle response. The optimized tube lengths and mitered collectors improve exhaust pulse timing, enhancing engine efficiency and power output. Additionally, these headers contribute to a more aggressive exhaust note, delivering a deeper and more refined sound that complements the Ram 1500’s muscular character without excessive drone.

Installation & Fitment

The aFe Twisted Steel Shorty Headers are designed for a straightforward, bolt-on installation using existing factory mounting points. They retain the stock catalytic converters, eliminating the need for cutting, welding, or drilling. This makes the upgrade accessible for both professional installers and experienced DIY enthusiasts. Fitment covers both 2WD and 4WD configurations of the Dodge Ram 1500 with the 5.7L Hemi engine from 2009 through 2018, ensuring broad compatibility across popular model years.
