1997–2006 Jeep Wrangler 4.0L
Part #: 1527SJS
Overview
The JBA Shorty Header in Silver Ceramic finish is a premium performance upgrade designed specifically for Jeep Wrangler models equipped with the 4.0L engine from 1997 through 2006. This header replaces the restrictive factory exhaust manifolds, significantly improving exhaust flow to enhance engine efficiency and power output. Ideal for Jeep enthusiasts seeking a reliable and durable solution to boost their vehicle’s performance, the JBA Shorty Header delivers noticeable gains in horsepower and torque without compromising daily drivability.
Engineered for both street and off-road use, this header is a smart upgrade for those who demand more from their Wrangler, whether towing, trail riding, or simply enjoying spirited driving. Its design maintains factory-style emission connections, ensuring compatibility with stock emissions equipment for a seamless integration.
Key Features
JBA’s Shorty Header offers a combination of advanced engineering and high-quality materials to maximize performance and durability. Key features include:
- Mandrel bent stainless steel tubing for smooth exhaust flow and increased durability
- Proprietary JBA Firecone collector design, proven in racing applications to optimize power and torque gains
- Extra thick collector domes for enhanced strength and heat resistance
- 3/8" thick machined flanges with oversized exhaust ports to reduce flow restrictions
- Factory-style emission connections for easy installation and compliance with emissions equipment
- Silver ceramic coating for corrosion resistance and improved heat management
- Includes high-quality hardware for a professional, leak-free installation
Construction & Design
Constructed from premium stainless steel, the JBA Shorty Header is built to withstand the rigors of daily driving, off-road abuse, and towing demands. The mandrel bending process ensures smooth, unrestricted exhaust flow by maintaining consistent tube diameter through bends, reducing turbulence and backpressure. The thick machined flanges provide a precise, secure seal to the cylinder head, minimizing leaks and improving longevity.
The signature Firecone collector design is a race-proven technology that enhances scavenging effects, improving exhaust gas evacuation and increasing engine efficiency. The silver ceramic coating not only protects the header from rust and corrosion but also helps retain heat within the exhaust gases, promoting faster catalytic converter light-off and reducing under-hood temperatures.
Performance & Sound
By replacing the restrictive stock manifolds, the JBA Shorty Header significantly improves exhaust flow, resulting in increased horsepower and torque across the RPM range. This upgrade enhances throttle response and overall engine efficiency, making your Jeep Wrangler more responsive and powerful. Additionally, the header contributes to a deeper, more aggressive exhaust note that complements the rugged character of the Wrangler without excessive drone.
Installation & Fitment
The JBA Shorty Header is designed as a direct bolt-on replacement for the 4.0L Jeep Wrangler models from 1997 to 2006. It retains factory-style emission connections, allowing for straightforward installation without the need for modifications to emissions equipment. Installation requires basic mechanical skills and standard hand tools. High-quality hardware is included to ensure a secure, leak-free fit. This header fits the Jeep Wrangler 4.0L engine platform precisely, ensuring compatibility and optimal performance.
