Key Features

The JBA Shorty Header incorporates advanced design elements and quality materials to maximize performance and longevity. Key features include:

• Mandrel bent stainless steel tubing for smooth exhaust flow and increased durability
• Proprietary JBA Firecone collector technology, proven to optimize power and torque delivery
• Factory-style emission connections to maintain compliance and ease of installation
• Extra thick collector domes for enhanced strength and heat resistance
• 3/8" thick machined flanges with oversized exhaust ports to reduce backpressure
• Silver ceramic coating for superior heat dissipation and corrosion resistance
• Includes high-quality hardware for a secure, no-leak installation

Construction & Design

Crafted from premium stainless steel, the JBA Shorty Header is engineered to withstand the harsh conditions encountered in off-road and daily driving environments. The mandrel bent tubes ensure consistent diameter throughout bends, minimizing flow restrictions and turbulence. The thick machined flanges provide a precise fit and durable sealing surface, preventing exhaust leaks over time.

The signature Firecone collector design uses race-proven principles to efficiently merge exhaust gases, improving scavenging and increasing power output where it matters most. The silver ceramic finish not only enhances the header’s appearance but also helps manage under-hood temperatures, protecting surrounding components and improving overall thermal efficiency.

Performance & Sound

By replacing the restrictive factory manifolds, the JBA Shorty Header reduces exhaust backpressure, allowing the engine to breathe more freely. This results in improved horsepower and torque, especially noticeable in mid-range RPMs where most daily driving occurs. Additionally, the header contributes to a more aggressive exhaust note, enhancing the Jeep’s sporty character without excessive drone.

Installation & Fitment

The JBA Shorty Header is designed as a direct bolt-on replacement for the 1997–2006 Jeep Wrangler 4.0L models, requiring no modifications to factory emission systems thanks to its integrated factory-style connections. Installation is straightforward for experienced mechanics and enthusiasts with basic hand tools. The included hardware ensures a tight, leak-free fit, and the durable construction guarantees long-lasting performance.
