Part #: 48-46202

Overview

The aFe Twisted Steel 409 SS Short Tube Header is a high-performance exhaust component designed to enhance your vehicle’s power and efficiency. Crafted for Jeep TJ models with a 4.0L I6 engine from 2000 to 2006, this mid-length tube header features precision engineering to optimize exhaust flow. Made from durable 16-gauge 304 stainless steel, it offers excellent resistance to corrosion and high temperatures. This header is ideal for enthusiasts seeking to improve engine response, increase horsepower, and achieve a more aggressive exhaust note. Its design supports maximum flow velocity across the entire power band, helping your vehicle deliver consistent performance and improved throttle response.

Key Features

This aFe Twisted Steel header combines advanced design with quality materials to deliver reliable performance and durability. Key features include:

• Constructed from 16-gauge 304 stainless steel for corrosion resistance and longevity
• Mid-length tube design for balanced flow and increased torque
• Optimum tube lengths and mitered collectors for enhanced exhaust velocity
• 100% TIG-welded for superior strength and precision craftsmanship
• Pulse control technology to improve exhaust scavenging and power delivery
• Mandrel-bent tubing to maintain consistent diameter and smooth airflow
• Designed specifically for Jeep TJ 4.0L I6 engines (2000-2006)

Construction & Design

The header’s construction emphasizes durability and performance, featuring mandrel-bent, near-equal length tubes that promote efficient exhaust flow. The TIG welding process ensures high-quality joints with maximum strength, while the mitered collectors are engineered to optimize pulse control and velocity. The stainless steel material not only withstands extreme heat but also resists corrosion, making it suitable for long-term use in demanding conditions.

Driving Feel & Feedback

Installing this header can help improve your vehicle’s exhaust response and overall driving feel. Expect a more aggressive sound and enhanced throttle response, contributing to a more engaging driving experience. The design supports better exhaust scavenging, which can translate into improved engine efficiency and a noticeable increase in power delivery across the RPM range.

Installation & Fitment

This header is designed as a direct replacement for the factory exhaust manifold on Jeep TJ models with a 4.0L I6 engine. Proper installation may require basic mechanical skills and standard tools. It is recommended to verify fitment against your vehicle’s specifications and consult professional installation if needed.

What’s Included

The package includes the Twisted Steel 409 SS Short Tube Header with all necessary mounting hardware for a straightforward installation. Additional components or gaskets are not typically included and should be sourced separately if required.
