PRODUCT SPOTLIGHT: CMI’S NEW 52O SPORT TUBES AND 520 E-TOP HEADERS

Generate more power from your stock 520 engine this season with CMI’s new 520 upgrade package that includes the 520 Sport Tubes and 520 E-Top Headers, the latest R+D project from the company that’s designed for the do-it-yourselfer.

Tested at Innovation Marine of Sarasota, FL. on a brand new 520 hp engine, some highlights of the 520 Sport Tubes include the ability to offer up to 48 hp more power, improved mid-range acceleration and torque, plus a featured downturn collector that improves water fill for improved mid-range acceleration and torque. It also features equalized primaries for greater performance.

The 520 E-Top Header, which is said to offer an increase of 31 hp, has a direct-replacement configuration that works with existing outlets, and offers improved mid-range acceleration and torque.

Both models also feature a patented “Cool Collar” design and are Mandrel bent and formed from high quality 316L grade stainless steel. They are also heat-treated (annealed) for added stress-relief and optimum durability.
