Big Block Chevy Gil Replacement Magnum Choice with Polished Risers 

Big Block Chevy Gil Replacement Magnum Choice with Polished Risers

This is the easiest bolt on system for increasing horsepower and performance.  The kit includes shift, electrical and oil filter brackets for easy installation.  This system fits all MerCruiser small and big block Chevy engines equipped with MerCruiser Silent Choice systems.  This system will save up to 75 lbs. in weight over cast iron systems.  All manifolds are coated and built for power and long life.

Hardin Exhaust Systems perform better because they're made better, with great attention to detail in design, engineering and manufacturing.  These manifolds are Hardincoated 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.
