Big Block Chevy Gil Replacement Aluminum Riser System

Big Block Chevy Gil Replacement Aluminum Riser System

Hardin Marine Offshore Wet Systems are designed for hi-performance and stock engines.  This system mixes and discharges exhaust gasses with cooling water at the end of the exhaust pipe, and then a rubber hose connects up to your exhaust thru-hull ports.  Custom pipes are also available for custom installations and are priced by measurements given.  This same system is also used on Mercury hi-performance 525SC and HP500-engine packages as standard equipment from Mercury Hi-Performance.

Hardin Exhaust Systems perform better because they're made better, with great attention to detail in design, engineering and manufacturing.  These manifolds are Hardin coated inside and out, proven to protect better than conventional marine coatings.  These exhaust pipes are designed to keep cooling water separated from the exhaust flow to avoid corrosion of valves, rings and pistons.  And these exclusive patented Turbulator Rings have proven themselves in protecting engines against water ingestion due to condensation.

Hardin Exhaust Systems are the overwhelming choice of boaters who want top-end performance with durability.  These exhaust systems deliver by allowing your engine to breathe easier and perform better.  Boaters spend thousands of dollars to modify their engines to increase horsepower and speed.  But, unless the exhaust system is capable of the additional flow required, the modifications are wasted.

These exhaust systems allow center to center engine dimensions of 32-5/16" and are 1-5/8" taller than Mercury cast iron manifolds mounted on stock short decks with GM Heads.

Big Block Chevy Gil Replacement Hardin Exhaust System

Changes in the marketplace have inspired us to blend two fabulous manufactures  products into one dynamic exhaust offering, thus bringing the very best performance manifold system available anywhere. This offering  brings to you an extremely high quality exhaust system upgrade, at an incredibly affordable price.  This performance exhaust system is suitable for both carbureted and EFI applications up to 500HP.

Hardin Marine has taken its years of exhaust tailpipe technology and designed a new tailpipe to fit most common MerCruiser big block Chevy engine applications.  This new tailpipe is manufactured from all 316L stainless steel with the same high quality you've come to expect. By creating a tailpipe  designed to fit most standard "Bravo" tailpipe exit locations affordability is maximized.  We have coupled it to the infamous Hardin Offshore performance exhaust manifold/headers found as standard equipment on carbureted Mercury HP 500's and Mercury Racing 540 Bulldog Packages. This manifold has forever been the most sought after and attempted to be duplicated manifold in the performance marine exhaust industry. At last you can own the "Original" at a cost even less than the imitations.

Take note of the jumper hose that runs from the manifold up to the tailpipe.  This hose transfers the cooling water from the manifold to the tailpipe for discharge and keeps the water totally isolated from your engine.  Many other systems on the market use an inferior thru-flange system to pass the engine cooling water to the tailpipe with only a thin gasket to seal the passage.  A simple gasket failure could be a catastrophic event allowing your engine to ingest a large volume of water costing thousands of dollars in repairs.

These exhaust systems allow center to center engine dimensions of 32-5/16" and are 1-5/8" taller than Mercury cast iron manifolds mounted on stock short decks with GM Heads.

The system also includes the patented Hardin Turbulators which trap and vaporize condensation before it can be ingested through your exhaust valves.  This one simple device, will significantly increase your engines life expectancy and is only available with Hardin exhaust.  This system is a complete "bolt-on" solution to your performance exhaust needs and includes:

  • 1 pair Hardin Offshore Exhaust Manifolds
  • 1 pair Hardin Marine Offshore Tailpipes (polished)
  • 1 Shift Cable Bracket
  • 1 Electrical Bracket
  • 1 Oil Filter Bracket
  • 2 patented Hardin Turbulators
  • All gaskets, bolts and fittings necessary for installation

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 mid range 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.
