Description

Its mandrel-bent design, with 1-5/8 inch primary tubes and a 2-1/2 inch collector, is optimized for scavenging and maximum performance gain. The header comes with a factory-applied black coating for pre-use protection that burns off during the first drive.

Pacesetter also offers an optional ARMOR*Coat ceramic finish for enhanced durability and heat resistance.
