AFE Shorty Headers (Raw Finish): Jeep Wrangler Rubicon 6.4L 392 2021 - 2025
aFe Shorty Headers
2021–2025 Jeep Wrangler 6.4L 392
Part #: 48-38031
Overview
The aFe Shorty Headers in raw finish are engineered specifically for the 2021 through 2025 Jeep Wrangler equipped with the potent 6.4L 392 engine. Designed to enhance exhaust flow and boost engine performance, these headers offer a direct bolt-on upgrade that delivers noticeable gains in horsepower and torque. Ideal for Jeep enthusiasts seeking improved throttle response and increased power without extensive modifications, these headers maintain factory sensor locations and fit seamlessly with the stock exhaust system.
Crafted with precision and durability in mind, the aFe Shorty Headers provide a reliable solution for drivers who want to maximize their Wrangler’s performance potential while preserving OEM compatibility and ease of installation.
Key Features
These shorty headers incorporate advanced design and quality materials to optimize exhaust flow and vehicle performance. Key features include:
- Up to +11 horsepower and +13 lb-ft of torque gains as verified on aFe’s in-house dyno
- 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.
What's Included
- aFe Shorty Headers (Raw Finish)
- Heavy-duty laser-cut machined mild steel flanges
- All necessary hardware for installation
- Instructions for bolt-on installation
Ideal For
These shorty headers are perfect for Jeep Wrangler 6.4L 392 owners who want to unlock additional power and torque while maintaining a factory-like fitment and ease of installation. They are well-suited for daily drivers, off-road enthusiasts, and performance seekers who desire improved throttle response and a more aggressive exhaust tone without compromising reliability or requiring extensive modifications.
Emissions Note
This product is not currently CARB exempt and is not available for purchase or use on vehicles registered in California or any state that requires CARB compliance. Please verify local regulations before purchasing.
