Cyclone "Shorty Header"

620-32001

Cyclone "Shorty Header"
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.

Cyclone High Performance Bravo Exhaust System

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.

Oil filter bracket, shift control bracket, ECU brackets, gaskets, and bolts are all included. They are "NOT" options like other brands.
