Cyclone Low Exit System Header System For GM Big Block Bravo 

Cyclone Low Exit System Header System For GM Big Block Bravo - Fully Polished

This Hardin Marine Cyclone system is designed around an application where an incorporated swim platform creates the need to exit the exhaust in a lower than standard location Through the use of a floating elbow positioning of the exit is somewhat maneuverable, these systems are perfect for limited access applications. Oil filter bracket, shift control bracket, and ECU bracket not included. Gaskets and bolts are included.

If you are one of thousands of performance boaters seeking the power and styling from stainless steel tubular headers then you're looking at the leader in exhaust technology. These "Cyclone" header systems share 100% 316L stainless steel construction. All appropriate flanges are laser cut and CNC machined for a perfect gasket seal. Each individual exhaust tube is bent to precise, exact tolerances every time. A computer designed fully welded water inlet manifold provides equal water distribution to each exhaust runner tube. While each set of headers goes through a 1900 degree annealing process that multiplies the durability factor of the header many times over while providing added protection against corrosion. But the heart of these systems lies in the ability to generate loads of additional power. By using CAD-5 Technology to develop a unique staggered tube runner length, these systems are capable of maximizing the broadest low end and midrange torque, all the while yielding incredible peak power gains. These systems are available in many configurations to fit every boaters needs. Rest assured when you lay down your hard earned money because the system comes complete with all necessary mounting bolts and gaskets making installation a snap.
