CMI Gen-X Replacement Headers for HP525, HP600 & HP700 EnginesĀ 

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

These are sold as a "pair of headers"

The new design increases water fill keeping the headers full at all time, creating cooler temperatures, which leads to improved longevity and a little 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.

MSRP: $11,000.00
