Construction & Design

Kooks utilizes premium T304 aircraft-grade stainless steel in the fabrication of these catted mid pipes, providing superior strength and resistance to rust and corrosion even under extreme heat and environmental exposure. Each pipe is handcrafted in the USA, reflecting decades of expertise in exhaust system manufacturing and ensuring precise tolerances and fitment.

The integrated OEM-style catalytic converters balance emissions requirements with performance, allowing these mid pipes to maintain compliance while minimizing exhaust flow restriction. The 3-inch diameter design promotes improved scavenging and reduced backpressure when paired with Kooks headers, enhancing overall engine efficiency and responsiveness.

Performance & Sound

When installed alongside Kooks long tube headers, these catted mid pipes contribute to a smoother and more efficient exhaust flow. This improved flow can translate into enhanced throttle response and potential power gains. The standard race catalytic converters help maintain emissions compliance without significantly muffling the exhaust note, preserving the aggressive yet refined sound signature that Kooks products are known for. Note that these mid pipes are intended for naturally aspirated setups and are not recommended for forced induction applications.

Designed for direct bolt-on installation with Kooks headers on compatible Dodge Durango and Jeep Grand Cherokee 5.7L HEMI models, these mid pipes require no major modifications. Installation is straightforward for experienced enthusiasts or professional shops, ensuring a secure, leak-free connection that integrates seamlessly with the rest of your exhaust system. Proper fitment guarantees optimal performance and durability.
