The Kooks Stainless Steel Longtube Headers and OEM Catted Mid Pipes are precision-engineered exhaust components designed exclusively for the 2006 to 2010 Jeep Grand Cherokee SRT8 equipped with the 6.1L V8 engine. This high-performance exhaust upgrade replaces the restrictive factory manifolds and mid pipes to significantly improve exhaust flow, resulting in enhanced horsepower, torque, and throttle response.
Crafted for enthusiasts who demand both street and track-ready performance, these headers and connection pipes deliver a perfect balance of power gains and aggressive exhaust tone without sacrificing emissions compliance. Whether you’re tackling spirited street driving, track days, or off-road adventures, this system offers a durable and reliable solution to unlock your SRT8’s full potential.
Engineered to optimize exhaust scavenging and reduce backpressure, the Kooks longtube headers and catted mid pipes provide measurable performance improvements. Key features include:
Kooks utilizes premium T304 stainless steel, known for its outstanding strength and resistance to rust and corrosion, ensuring long-lasting durability even under extreme heat and harsh conditions. The longtube header design enhances exhaust gas velocity and scavenging, which helps unlock additional horsepower and torque from the 6.1L V8 engine.
Each header is mandrel-bent to maintain smooth airflow and precision-welded to preserve structural integrity and exact fitment. The catted mid pipes feature a 3 inch diameter with OEM-style outlets, allowing for a clean transition to the rest of the exhaust system while maintaining emissions compliance. Every component is handcrafted in the USA, reflecting Kooks’ commitment to quality and performance.
Replacing the factory manifolds and mid pipes with Kooks longtube headers and catted connection pipes dramatically improves exhaust flow, resulting in enhanced throttle response and increased power output. The system also produces a deeper, more aggressive exhaust note that complements the muscular character of the Jeep Grand Cherokee SRT8 without excessive drone, delivering an exhilarating driving experience.
These headers and mid pipes are engineered for direct bolt-on installation on 2006–2010 Jeep Grand Cherokee SRT8 models equipped with the 6.1L engine. Installation requires standard hand tools and moderate mechanical experience. No cutting or major modifications are necessary, making this a straightforward upgrade for enthusiasts seeking improved performance and sound.
This Kooks header and connection pipe system is ideal for Jeep Grand Cherokee SRT8 owners who want a high-quality, durable exhaust upgrade that enhances power, sound, and overall driving enjoyment. Perfect for street performance, track use, and off-road excursions, these components provide a reliable and performance-focused solution tailored to the 6.1L V8 engine.

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!
