• TIG-welded, machined 3/8" header flange guarantees a leak-free seal and maximum structural integrity
• Compatible with all factory OE components for seamless integration
• Premium aluminum header gaskets included for reliable sealing
• Coated in high heat resistant black paint for corrosion protection and a stealthy appearance

Construction & Design

Built from heavy-duty 16-gauge steel tubing, these Flowtech headers are mandrel bent to maintain consistent tube diameters, which optimizes exhaust gas flow and reduces turbulence. The smooth 1-5/8" primary tubes transition seamlessly into a 2-1/2" ball and socket collector, engineered to mate perfectly with the factory exhaust system. The header flange is precision-machined and TIG-welded to ensure a tight, leak-free connection that withstands heat and vibration over time.

The entire assembly is finished in a durable high-temperature black paint that resists corrosion and adds a subtle, stealthy look under the hood. This combination of materials and craftsmanship ensures these headers deliver both performance and longevity.

Performance & Sound

By increasing exhaust flow efficiency, these shorty headers help your Jeep Wrangler’s 3.8L V6 engine breathe better, resulting in improved throttle response and more usable power throughout the RPM range. The enhanced exhaust velocity also contributes to a more aggressive exhaust note without excessive drone, complementing other aftermarket upgrades such as cold air intakes and cat-back exhaust systems.

Installation & Fitment

Designed as a direct replacement for the factory manifolds, Flowtech shorty headers install easily on 2007–2011 Jeep Wrangler JK models with the 3.8L V6 engine, compatible with both 2WD and 4WD configurations. The OE-style ball and socket collector connects directly to the factory exhaust head pipe, eliminating the need for cutting or welding. Installation requires basic hand tools and moderate mechanical skill, making it accessible for experienced DIYers and professional installers alike.
