The American Racing Headers (ARH) Full System for the Jeep Grand Cherokee 5.7L Hemi (2011–2021) is a premium long tube header upgrade designed to maximize exhaust flow and enhance engine performance. Crafted specifically for enthusiasts seeking improved horsepower, torque, and throttle response, this full system replaces the factory exhaust manifolds with expertly engineered headers and collectors. It is ideal for those who want a durable, high-quality exhaust solution that delivers both performance gains and a distinctive exhaust note.
ARH’s full system is engineered to provide a precise fit and superior flow characteristics, making it a perfect choice for street performance and racing applications. Whether you are upgrading your Jeep for spirited driving or track use, this system offers a reliable and effective way to unlock the potential of your 5.7L Hemi engine.
This full system incorporates advanced design elements and premium materials to ensure outstanding performance and durability:
The ARH Full System is built from premium 304 stainless steel, known for its excellent resistance to heat and corrosion. The headers feature thick 3/8" laser-cut flanges that maintain a perfect seal and resist warping under extreme temperatures. Each inlet is hand-ported and TIG welded to ensure smooth airflow and structural integrity. The long tube primaries are carefully routed to optimize exhaust gas velocity and fitment within the engine bay, minimizing installation challenges and maximizing performance.
Merge collectors incorporate scavenger spikes, a design feature that enhances exhaust scavenging by improving the evacuation of exhaust gases from the cylinders. This results in better cylinder filling on the intake stroke, contributing to improved power output and throttle response.
By replacing restrictive factory manifolds with long tube headers and high-flow merge collectors, this ARH full system significantly improves exhaust flow, which can lead to noticeable gains in horsepower and torque. The system’s design also enhances the exhaust sound, delivering a deeper, more aggressive tone that complements the muscular character of the 5.7L Hemi engine. This upgrade is ideal for drivers who want both performance improvements and an enhanced auditory experience.
The ARH Full System is engineered for a direct bolt-on installation on 2011–2021 Jeep Grand Cherokee models equipped with the 5.7L Hemi engine. The system’s optimized tube routing and precision flanges ensure a great fit with minimal modifications required. Installation typically involves removing the factory exhaust manifolds and replacing them with the ARH headers and collectors. Professional installation is recommended to ensure proper fitment and to maintain vehicle performance and safety standards.
This full system is perfect for Jeep Grand Cherokee 5.7L Hemi owners who want to enhance their vehicle’s performance and exhaust sound. It is especially suited for enthusiasts involved in street performance, weekend racing, or those who demand a high-quality, durable exhaust upgrade that is built to last. The system’s design also appeals to those who value American-made craftsmanship and precision engineering.

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!
