620-32001 Cyclone "Shorty Headers"
Replacement Header For Gil Marine, Mercury Hi-Performance & Rex Power Torque Manifolds
Fully Polished Finish
Do your performance manifolds look like these but your stainless steel tailpipes still look like jewelry? This is a common problem with a number of aftermarket high performance exhaust manifolds, the solution is to replace them with the Cyclone "Shorty"! An all 316L stainless steel header designed as a direct bolt-on replacement for your cast aluminum manifolds.
By retaining your existing stainless steel tailpipe or riser, you can remove your existing manifolds and simply slide the new "Shorty Header" into place and connect your existing tailpipes. These units are currently available to replace Mercury Hi-Performance, Gil Marine, and Rex Marine Power Torque manifolds. Each header is manufactured to the highest quality standard using 100% 316L stainless steel construction, laser machined flanges for a perfect gasket seal, and exhaust tubes that are B.T.B. bent to exact tolerances every time. A 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 was used to develop the staggered length exhaust tube runners which provide for broader low and mid range torque, while yielding incredible peak power. This kit comes complete with all necessary bolts and gaskets to attach to your engine. Riser gaskets are not included, and you may need up to 4 gaskets depending on application. See related parts.

diverter built-in This gorgeous, one-piece-design tailpipe is the perfect
choice for the power hungry boater who is seeking to reduce noise This
system is sold complete with all necessary hose fittings, pump, gaskets, and bolts. Oil filter bracket, shift control bracket, and ECU bracket not 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.

620-32025 Cyclone High Performance Bravo Exhaust System
The Cyclone HP Bravo exhaust system is a water jacketed wet
style exhaust header. This system is an excellent choice for both stock and
modified performance applications. The tailpipe design provides a steep angle
and high centerline making the cooling water discharge resistant to water reversion, correcting what was a common problem in many HP 500 applications. This is the perfect replacement exhaust system for the HP500 style engine packages. This
header mixes the engine cooling water with the exhaust near the end of the
tailpipe which is then connected to a 4" rubber hose exhaust that connects to the
transom mounted exhaust tips. Gaskets, and bolts are all included.
