3″ Taller , Leaned Port Side Sweeper Header
The all polished, port side 3” taller, leaned CMI Sport Tubes are a superior long tube header designed for both racing or any high-performance application. These leaned, taller headers are commonly used on front motor Mercury 525-700 series motors on Cigarette reverse stagger builds. These headers feature the CMI Flex Flare Tailpipe Connection. For big-block applications, where maximum scavenging and horsepower are required, CMI Sport Tube headers deliver peak performance and power from naturally aspirated engines.
