420-901020 Big Block Chevy Low Exit 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

420-901018-SD Big Block Chevy Gil Replacement Bravo Wet Offshore 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.
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.
Priced according to your dimensions. Submit your
