The Stainless Works Long Tube Headers and Mid Pipes are precision-engineered exhaust components designed specifically for the 2012–2018 Jeep Grand Cherokee equipped with the 6.4L SRT8 V8 engine. This system replaces the factory exhaust manifolds and mid pipes with a high-performance solution that improves exhaust flow, enhances throttle response, and increases horsepower. Ideal for enthusiasts seeking a durable, bolt-on upgrade, these headers and mid pipes deliver a more aggressive exhaust tone while maintaining reliability and emissions compliance.
Whether you are upgrading your daily driver or preparing your Jeep for spirited driving, Stainless Works provides a premium exhaust system that balances performance gains with street legality and long-term durability.
Designed to optimize exhaust scavenging and durability, this header and mid pipe system includes:
Stainless Works builds these headers and mid pipes from high-grade 304 stainless steel, renowned for its excellent corrosion resistance and structural integrity. The tubes are mandrel bent to create smooth, unrestricted pathways that minimize backpressure and maximize engine efficiency. Each component is meticulously TIG welded to ensure a robust, leak-free assembly capable of withstanding the demands of high-performance driving and harsh environmental conditions.
The port-matched flanges guarantee a perfect seal against the cylinder heads, simplifying installation and preventing exhaust leaks. The inclusion of 3" high-flow catalytic converters balances performance improvements with emissions requirements, making this system suitable for street-driven vehicles where legal compliance is necessary.
Upgrading to Stainless Works long tube headers and mid pipes significantly enhances the breathing capability of the 6.4L V8 engine. This results in improved throttle response, increased horsepower, and a more aggressive exhaust note that reflects the true character of the SRT8 powerplant. The smooth mandrel bends and high-flow catalytic converters optimize exhaust gas evacuation, reducing engine strain and improving overall efficiency.
This header and mid pipe system is designed as a direct bolt-on replacement for the factory manifolds and mid pipes on the Jeep Grand Cherokee 6.4L SRT8 models from 2012 through 2018. The port-matched design ensures a precise fit, requiring minimal modifications during installation. Typical installation can be completed with standard hand tools and moderate mechanical experience. Detailed instructions are included to assist with a smooth and accurate installation process.
This header and mid pipe system is perfect for Jeep Grand Cherokee SRT8 owners who want to unlock additional power and improve exhaust sound without sacrificing emissions compliance. It is well suited for performance enthusiasts seeking quality craftsmanship, durability, and a noticeable upgrade in engine responsiveness for both street and track use.
Stainless Works does not ship headers, downpipes, catalytic converters, or any parts affecting motor vehicle emission control to addresses in California. This product includes high-flow catalytic converters but may not be CARB-compliant for all states. Please verify local regulations before purchasing.
Stainless Works builds exhaust systems, mufflers, and fabrication components. Designed for enthusiasts who want sound, flow, and fitment, their exhaust solutions balance fitment, tone, and performance-minded flow characteristics. If you’re upgrading for a more engaging sound and a cleaner, higher-quality exhaust setup, Stainless Works is a proven name in the aftermarket.
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!
