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.
