Kooks 1-7/8" Stainless Headers & Catted Connection Kit (3610H421) - Jeep Grand Cherokee & Dodge Durango 5.7L

Unlock improved power, throttle response, and a refined performance exhaust note with the Kooks 1-7/8" Stainless Header and Catted Connection Kit for 5.7L HEMI-equipped Grand Cherokee and Durango models. Designed to replace restrictive factory manifolds, this system delivers efficient exhaust scavenging while retaining catalytic converters for a balanced street-performance setup.

Built from premium stainless steel, the long tube headers feature mandrel-bent 1-7/8" primaries flowing into 3" collectors to reduce backpressure and improve overall engine efficiency. The included OEM-style stainless catted connection pipes ensure a clean bolt-on installation and proper integration with the factory-style exhaust. Precision construction, durable materials, and vehicle-specific fitment make this kit an ideal upgrade for daily-driven or performance-oriented HEMI SUVs.
