Standard Straight Back Sweeper
The all polished, straight back CMI Sweeper style are a superior long tube header designed for both racing and any high-performance application. These leaned, taller headers are commonly used in custom or staggered set up Mercury 525-700 series motors. These headers feature the CMI Flex Flare Tailpipe Connection. For big-block applications, where maximum scavenging and horsepower are required, CMI Sweeper headers deliver peak performance and power from naturally aspirated engines.
