Are CMI Headers Your Next Headers?

All CMI headers are built to high quality standards which has made it one of the top choices for customers looking to increase the performance of their boat.

CMI headers are manufactured using high quality materials, like 316L stainless steel, which offer strong corrosion resistance compared to milder steels. CMI's unique tube bending, and welding processes assures uniform wall thickness and significantly reduces internal stresses that commonly cause fatigue, corrosion and premature failure in most high performance applications.

Along with their header systems, CMI also builds custom tailpipes to fit almost any unique engine installation. With CMI, boaters can expect a solid combination of performance and reliability, making it one of the top exhaust brands the market.
