Part #: 3410H641
The Kooks 1-7/8" x 3" Longtube Headers paired with OEM catted mid pipes are precision-engineered exhaust components designed specifically for high-performance 6.4L SRT and 6.2L Trackhawk HEMI engines found in Jeep Grand Cherokee SRT8, Trackhawk, and Dodge Durango SRT 392 models. This complete header and mid pipe system enhances exhaust flow, resulting in improved horsepower, torque, and throttle response while delivering an aggressive exhaust tone that complements the vehicle’s performance character.
Ideal for enthusiasts seeking to maximize their vehicle’s power output and exhaust efficiency, these Kooks headers and mid pipes bolt directly to the factory exhaust system using Kooks connection pipes, ensuring a straightforward installation without the need for extensive modifications.
Designed with advanced engineering and quality materials, this system offers:
Kooks utilizes premium 304 stainless steel for these headers and mid pipes, providing excellent resistance to heat and corrosion, essential for long-term durability in high-performance applications. The headers feature mandrel-bent tubing that maintains consistent diameter through bends, reducing flow restrictions and turbulence. TIG welding ensures strong, precise joints that withstand thermal cycling and vibration. The inclusion of venturi merge spikes at the collector improves exhaust scavenging by promoting efficient gas flow and reducing backpressure.
The mid pipes incorporate OEM catalytic converters with options for standard or EPA-certified GREEN and HIGH OUTPUT GREEN cats, balancing emissions compliance with performance. Flanges are expertly blended to ensure a perfect seal and ease of installation.
This Kooks header and mid pipe system significantly enhances exhaust flow dynamics, resulting in noticeable gains in horsepower and torque. The improved scavenging effect leads to better throttle response and engine efficiency. Additionally, the system produces a more aggressive and refined exhaust note that complements the muscular character of the 6.2L and 6.4L HEMI engines without excessive drone.
Designed as a direct bolt-on upgrade, these headers and mid pipes connect seamlessly to the factory exhaust system using Kooks connection pipes, minimizing installation complexity. The kit includes O2 sensor extension harnesses to accommodate sensor positioning. Professional installation is recommended to ensure proper fitment and optimal performance. No major modifications to the vehicle’s exhaust or engine bay are required.
This system is perfect for Jeep Grand Cherokee SRT8 and Trackhawk owners, as well as Dodge Durango SRT 392 enthusiasts, who want to unlock additional power and torque from their factory 6.2L or 6.4L HEMI engines. It suits drivers seeking a high-quality, durable exhaust upgrade that improves performance and delivers an aggressive exhaust tone without sacrificing emissions compliance outside California.
These headers and mid pipes are not CARB compliant and are not legal for sale, installation, or use in California. The GREEN and HIGH OUTPUT GREEN mid pipe options are EPA-certified for 49-state legality, providing emissions-compliant choices for most regions.

ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
