• Constructed from mandrel-bent 304 stainless steel tubing ranging from 1-7/8 inch to 3 inch diameter for strength and durability
• Heavy-duty laser-cut machined mild steel flanges ensure a secure, leak-free seal
• 4-to-1 mitered merge collectors reduce turbulence and increase exhaust velocity
• 100% MIG-welded construction for enhanced strength and long-lasting durability
• Retains factory oxygen sensor locations for seamless integration with stock electronics
• Designed to work with the factory exhaust system without requiring modifications
• Engineered using computer-aided design (CAD) for precise, high-tolerance fitment

Construction & Design

The aFe Shorty Headers are built from premium 304 stainless steel, known for its corrosion resistance and ability to withstand high temperatures. The tubing is mandrel-bent to maintain consistent diameter throughout bends, which promotes smooth exhaust gas flow and minimizes restrictions. The headers feature heavy-duty laser-cut flanges made from machined mild steel, providing a durable and leak-proof connection to the factory exhaust manifold.

The 4-to-1 mitered merge collectors are a standout design element, engineered to reduce exhaust turbulence and increase velocity. This design improves scavenging effects, which translates into better horsepower and torque output. Every weld is completed using 100% MIG welding techniques, ensuring robust joints that can endure the rigors of daily driving and off-road conditions.

Performance & Sound

By improving exhaust flow dynamics, these shorty headers deliver measurable performance enhancements. Testing on aFe’s dyno has shown gains of up to 11 horsepower and 13 lb-ft of torque, providing a noticeable boost in acceleration and throttle response. The optimized exhaust velocity also contributes to a more aggressive exhaust note, enhancing the driving experience without excessive drone.

Installation & Fitment

Installation is straightforward thanks to the use of factory-style flanges and precise CAD engineering. The headers bolt directly into the stock locations on the 2021–2025 Jeep Wrangler 6.4L 392 engine, requiring no cutting, welding, or other modifications. Factory oxygen sensor ports are retained, allowing for easy sensor installation and ensuring compliance with vehicle electronics. This makes the upgrade accessible to enthusiasts looking for a hassle-free installation process.
