The American Racing Headers (ARH) Full System for Jeep Grand Cherokee 6.4L SRT models from 2012 through 2021 is engineered to deliver exceptional exhaust flow and performance gains. Designed specifically for the SRT8 and SRT variants, this long tube header system replaces the factory exhaust manifolds with precision-crafted stainless steel primaries, merge collectors, and scavenger spikes. Enthusiasts seeking improved horsepower, torque, and throttle response will appreciate the meticulous fitment and durable construction of this full system.
ARH’s full system is ideal for racers and performance-minded Jeep owners who demand uncompromising quality and race-proven technology. It offers a direct bolt-on fitment with optimized tube routing to maximize exhaust scavenging and minimize restrictions, ensuring your 6.4L V8 breathes more efficiently under all driving conditions.
This full system incorporates advanced design elements and premium materials to enhance both performance and reliability:
The ARH Full System is built from premium 304 stainless steel, chosen for its excellent strength and resistance to heat and corrosion. The 3/8" thick laser-cut flanges provide a solid, warp-resistant mounting surface, preventing exhaust leaks and ensuring long-term durability. Each header inlet is hand-ported and TIG welded to guarantee smooth airflow transitions and precise fitment to the cylinder heads.
The long tube primary design enhances exhaust scavenging by allowing exhaust pulses to exit more efficiently, reducing backpressure and improving engine breathing. The 3" merge collectors incorporate scavenger spikes, a unique ARH technology that helps maintain exhaust gas velocity and improves overall flow dynamics. This combination results in a system that not only fits perfectly but also delivers measurable performance benefits.
This full header system is engineered for direct bolt-on installation on 2012–2014 Jeep Grand Cherokee 6.4L SRT8 and 2015–2021 Jeep Grand Cherokee 6.4L SRT models. The optimized tube routing and precise flange alignment minimize the need for modifications, making installation straightforward for experienced mechanics. However, due to the nature of long tube headers, some adjustments to factory components or exhaust hangers may be necessary depending on the vehicle’s configuration.
It is important to note that these headers are designed exclusively for racing use and are not legal for street use on public roads or highways. Installation on any vehicle used on public roads may result in fines or legal penalties under the Clean Air Act.
This full system is perfect for Jeep Grand Cherokee SRT owners who participate in track events, drag racing, or other motorsport activities where maximizing engine performance is critical. It is also suitable for enthusiasts looking to upgrade their exhaust system with a high-quality, race-proven header solution that offers improved power delivery and throttle response.
All American Racing Headers products, including this full system, are manufactured exclusively for racing purposes. Installation on any vehicle intended for use on public roads or highways is illegal and may subject the owner to fines or criminal liability under the Clean Air Act.

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!
