.Cyclone headers
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, gaskets, and shift and oil filter brackets making
installation a snap

Cyclone Water Jacketed Header System
This Cyclone wet exhaust series header works perfectly on both
stock and modified performance applications. This header mixes
engine cooling water with the exhaust near the end of the tailpipe.
That allows you to use a 4" rubber hose connection to attach your
transom mounted exhaust tips. This is the perfect replacement for
your factory exhaust system. Oil filter, shift control, ECU brackets,
gaskets, and bolts included.

Cyclone Sound-Select System
This is one of the easiest horsepower enhancing exhaust systems
available today! For boats currently using a switch-able exhaust
diverter system, this was designed to replace MerCruiser big
block silent choice systems. This system will save up to 80 lbs.
compared to cast iron ones. Oil filter, shift control, ECU brackets,
gaskets, and bolts included

Cyclone "Shorty Header" - Replacement Header For Gil
Marine, Mercury Hi-Performance & Power Torque Manifolds
If you're one of the thousands of customers making the migration
away from after-market exhaust manifolds, to the ultimate power
producing tubular header systems, then Hardin Marine has
developed the answer in their manifold replacement "Shorty
Header". These units are designed to directly replace your cast
aluminum manifolds. By retaining your existing stainless steel
tail/riser pipe, you can remove your dated manifolds and simply
slide the new "Shorty Header" into place and re-install your existing
tailpipe. These units are currently available to replace Mercury
Hi-Performance, Gil Marine, and Rex Marine Power Torque
manifolds with more new models available soon. Each header
shares 100% 316L stainless steel construction, laser machined
flanges for a perfect gasket seal, exhaust tubes are B.T.B. bent to
exact tolerances every time. Fully welded computer designed water
inlet manifold assures equal water flow to each individual exhaust
tube. These headers are completely annealed to maximize durability
while preventing corrosion. CAD-5 technology develops a
staggered length exhaust tube runner for broader low and mid
range torque, while yielding incredible peak power. Every kit comes
complete with all necessary attaching bolts and gaskets so you can
rest assured that you're getting everything that you need.

Cyclone Low Exit System (below platform)
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, shift control, ECU brackets, gaskets, and
mounting hardware are included
