The long tube design features a stepped primary diameter that enhances exhaust gas velocity and reduces backpressure, resulting in improved engine efficiency and power output. The green catted connector pipes maintain emissions compliance while optimizing flow, and the inclusion of an EPS block off plug ensures proper sensor function without the need for additional modifications.
Every component is precision TIG welded and hand-finished to exacting standards, reflecting Kooks’ commitment to quality and performance. This attention to detail ensures a perfect fit and long-lasting durability, even under the rigorous demands of street and track use.
Performance & Sound
By replacing restrictive factory manifolds and connection pipes, this Kooks header kit significantly improves exhaust flow, which translates into noticeable gains in horsepower and torque across the powerband. The enhanced scavenging effect of the long tube headers promotes quicker turbo spool or naturally aspirated throttle response. Additionally, the system produces a deeper, more aggressive exhaust note that complements the muscular character of the HEMI engine without excessive drone.
