Schoenfeld Crossover Headers 1-5/8- 1-3/4 Crate Motor 135VHCM-3

Efficient exhaust scavenging is non-negotiable on the circle track, and Schoenfeld's crossover headers are engineered to maximize flow velocity and minimize back-pressure in your small-block Chevy crate motor setup. The stepped primary tubes—transitioning from 1-5/8" to 1-3/4"—allow you to optimize scavenging across your RPM range, while the 3" collector keeps exhaust gases merging smoothly without turbulence. For crate motor competitors who demand bolt-on reliability without compromise, this is a proven platform that will pay dividends in throttle response and mid-range grunt.
