Construction & Design

These headers and mid pipes are crafted from high-quality 304 stainless steel, renowned for its resistance to corrosion and ability to withstand high temperatures typical of performance exhaust systems. The mandrel-bent tubing ensures smooth, unrestricted exhaust gas flow by maintaining a consistent diameter through bends, minimizing turbulence and backpressure.

Each joint is meticulously TIG welded to provide robust, leak-free connections that endure the stresses of daily driving and spirited performance use. The port-matched flange design guarantees a perfect seal against the cylinder head, reducing exhaust leaks and improving overall efficiency. The polished finish resists rust and discoloration, maintaining a clean appearance over time.

Performance & Sound

Replacing the factory exhaust manifolds with these long tube headers and high-flow mid pipes significantly improves exhaust gas evacuation from the 5.7L Hemi engine. This results in enhanced engine efficiency, quicker throttle response, and a more aggressive exhaust note that complements the muscular character of the Jeep Grand Cherokee. The optional high-flow catalytic converters help maintain emissions compliance while preserving strong exhaust flow and performance gains.
