Big Block Chevy HP500 Gil Replacement Hardin Exhaust System 

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)
  • 2 patented Hardin Turbulators
  • All gaskets, bolts and fittings necessary for installation
