Featuring a 3-tube design, the outer primary tubes are 1-5/8″ diameter, while the center (or inner) tube is 1-7/8″ diameter, and then exits through a 2½” collector.

Please compare the dimensions of this header set with those of the CAD391 (specifically the driver-side header) to confirm which is the best choice for the application. The CAD391 is best for original, factory chassis applications, and the CAD392 is best suited for applications using aftermarket chassis and steering.

NOTE: Does not include header bolts. Please source appropriate fasteners elsewhere.

This aerospace and military-grade technology adds excellent protection to your headers while offering the benefit of thermal control in your engine bay. It also improves cylinder scavenging of exhaust gases and increases the longevity of your header investment.
