aFe Twisted Steel Header Turbo Manifold (T4)

Fits 1998.5–2002 Dodge Diesel Trucks with 5.9L L6 Engine

Part #: 48-32019

Overview

The aFe Twisted Steel Header Turbo Manifold is a high-performance exhaust component designed specifically for Dodge diesel trucks equipped with the 5.9L inline-six engine from 1998.5 to 2002. Crafted from mandrel-bent 304 stainless steel, this manifold features 1-3/4" head pipes stepped to 2" with .120 wall thickness, ensuring durability and optimal flow. TIG welded for strength, it provides a robust solution for enthusiasts looking to enhance turbo response, increase horsepower, and improve overall engine efficiency. This manifold is ideal for those seeking to support larger turbos and maximize the potential of their diesel powertrain. Whether you're upgrading for increased towing capacity, improved throttle response, or enhanced performance tuning, this header offers a reliable and durable upgrade that complements your vehicle’s existing setup. Its precision engineering and high-quality materials help reduce exhaust backpressure, supporting quicker spool times and more responsive acceleration.

Key Features

Designed with performance and durability in mind, the aFe Twisted Steel Header Turbo Manifold offers several key benefits:

• Constructed from mandrel-bent 304 stainless steel for corrosion resistance and longevity
• Stepped 1-3/4" head pipes to 2" for improved exhaust flow
• Laser-cut T-4 divided diesel flange for precise fitment and sealing
• Includes 1/8" EGT ports for auxiliary sensors and equipment
• Welded with TIG for enhanced strength and durability
• Supports larger turbochargers for increased boost and power
• Engineered to optimize turbo spool and throttle response

Construction & Design

This manifold features mandrel-bent stainless steel tubing with a stepped design to maximize exhaust flow and reduce restrictions. The TIG welding process ensures a strong, durable joint capable of withstanding high temperatures and harsh operating conditions. The laser-cut T-4 flange provides a precise fit for T-4 turbochargers, facilitating easier installation and a secure seal.

Driving Feel & Feedback

Upgrading to this header can help improve turbo response and overall engine efficiency, resulting in quicker spool times and more immediate power delivery. The design promotes better exhaust scavenging, which can enhance throttle feel and driving dynamics, especially under load or during acceleration.

Installation & Fitment

This turbo manifold is designed as a direct bolt-on replacement for 1998.5–2002 Dodge diesel trucks with the 5.9L inline-six engine. Proper installation may require basic mechanical skills and standard tools. It is recommended to follow manufacturer instructions for optimal fitment and performance.

What’s Included

The package includes the Twisted Steel header with all necessary mounting hardware and the T-4 divided flange. Additional components or accessories are not included.
