The Kooks 1.875" Longtube Headers paired with OEM GREEN Catted Mid Pipes are engineered specifically for the 2011–2021 Jeep Grand Cherokee and 2011–2024 Dodge Durango R/T equipped with the 5.7L VVT HEMI engine. Designed for enthusiasts seeking to enhance exhaust flow, increase horsepower, and improve throttle response, this complete header and mid-pipe system offers a direct bolt-on upgrade that maintains emissions compliance with the included OEM GREEN catalytic converters.
Kooks Headers and Exhaust has been a leader in high-performance exhaust technology since 1962, with decades of racing heritage and a commitment to quality craftsmanship. This system is ideal for street and light off-road use, delivering a balance of performance gains and reliable operation without sacrificing emissions standards.
Built to exacting standards, the Kooks 1.875" Longtube Headers with OEM GREEN Catted Mid Pipes provide numerous benefits:
Kooks utilizes premium-grade stainless steel tubing for these longtube headers, ensuring excellent corrosion resistance and long-lasting durability. The 1.875" diameter tubing is carefully mandrel bent to maintain smooth bends that maximize exhaust gas velocity and minimize turbulence. The headers feature thick flanges and precision welds to guarantee a leak-free seal and robust structural integrity.
The OEM GREEN catted mid pipes integrate factory-grade catalytic converters that meet emissions standards while complementing the enhanced flow characteristics of the headers. This combination preserves the vehicle’s environmental compliance without compromising performance gains.
This Kooks header and mid-pipe system is designed for a direct bolt-on installation on 2011–2021 Jeep Grand Cherokee and 2011–2024 Dodge Durango R/T models equipped with the 5.7L VVT HEMI engine. No cutting or welding is required, and the system uses factory mounting points and hardware for a secure fit. Installation typically requires moderate mechanical skills and standard hand tools.
It is recommended to have a professional or experienced technician perform the installation to ensure proper fitment and to avoid potential exhaust leaks. The system is compatible with the factory exhaust downstream of the mid pipes, allowing for seamless integration with stock or aftermarket components.
This Kooks longtube header and mid-pipe system is perfect for Jeep Grand Cherokee and Dodge Durango R/T owners who want to unlock additional power and improve exhaust efficiency without sacrificing emissions compliance. It suits enthusiasts who use their vehicles for spirited street driving, occasional towing, or light off-road adventures and desire a high-quality, American-made performance upgrade.

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!
