Gen-X Headers

CMI's Gen-X Headers are a direct factory replacement for Mercury Racing HP525EFI, HP600SCi and HP700SCi engines.

The new design increases water fill keeping the headers full at all times, creating cooler temperatures, which leads to improved longevity and extra horsepower.

Featuring more equalized primaries for improved performance, the straight-back headers with downturn collectors work with existing tailpipes and are easy to install. Constructed of quality 316L domestic stainless steel makes for one tough header with a sleek stylish look.
