THE ULTIMATE "FRESH WATER" EXHAUST SYSTEM

Finally an affordable alternative to all stainless steel water jacketed headers. For the thousands of pleasure boaters "NOT" affected by the corrosion problems associated with Salt Water there is at last the availability of a true tubular header system for the Fresh Water boater. These headers are designed to be a replacement for Mercury manifolds. However, they terminate approximately 8" aft of stock manifolds and are projected to meet the exhaust tips providing they are in the stock location. Low Port Headers are also available for under the swim step applications. Standard width headers will have about 1/2" clearance between header and tall style Moroso valve cover. Headers come complete with bolts, gaskets, water fittings, pet cocks, etc. (less 4" hose and 4" hose clamps). Factory oil filter requires relocation.

THE LIGHTNING CONSTRUCTION DIFFERENCE IS WHAT COUNTS !
Our Magnum header starts with Mandrel bent 316L stainless steel interior tubes. The exterior tubes are Mandrel bent heavy wall steel tube (.074). The tubes are then mechanically etched by sand blasting and then assembled. Finally,a corrosion resistant silicone ceramic coating is applied to the interior of the header while the exterior receives a powder coat finish.

ALL THIS PLUS THE BEST 2-YEAR WARRANTY IN THE INDUSTRY

Through continuing research Lightning Mfg. has developed a Dual Porcelain Coating that resists corrosive water environments. Now able to apply the same high tech coating to the fresh water series of steel outer lined thus aiding in the prevention cracking and deterioration.

LIGHTNING PERFORMANCE
When comparing performance exhaust systems it's good to understand the different systems on the market today and the performance demands of yourengine. Understanding how a header works will help you decide on which exhaust system is best suited for your application.

Headers have two basic functions. First is to simply relieve back pressure. For example, when looking at a manifold you see a 4" diameter exhaust hose, but theactual exhaust gas opening is about 2-1/2" diameter. Most performance manifolds and some header manufacturers use a 4" exhaust hose and 3" or 3-1/2" OD exhaustgas tube. All of these headers use a 4" OD exhaust gas tube and a 5" water jacket tube until the water gets introduced into the exhaust gas stream, then it getsreduced from 5" to its 4" exhaust hose diameter. At no time does the exhaust gases see a diameter smaller than 4" OD. When looking at these exhaust gas openingsconsider their area not their diameter. For example, a 4" OD opening has an area of approximately 12.56 sq. in. A 3-1/2" opening has an area of approximately 9.62 sq. in.That is 25% smaller! A 3" opening is approximately 7.06 sq. in. and a 2-1/2" opening is approximately 4.90 sq. in. which is 60% smaller.

LIGHTNING HORSE POWER COMPARISON
Performance figures on headers vary considerably. As a rule, the higher horsepower engines benefit more than the lower horsepower engines. For example, the 330hp Mercury engine will gain approximately 50 to 75 rpm, where as the 365 hp Mercury engine will gain approximately 300 to 400 rpm (45 hp). Blown engines gain upto 800 rpm (80 hp). Of course this is comparing these headers against stock Mercury center rise manifolds.

THE LIGHTNING CONSTRUCTION DIFFERENCE IS WHAT COUNTS !

Our Magnum header starts with Mandrel bent 316L stainless steel interior tubes. The exterior tubes are Mandrel bent heavy wall steel tube (.074). The tubes are then mechanically etched by sand blasting and then assembled. Finally,a corrosion resistant silicone ceramic coating is applied to the interior of the header while the exterior receives a powder coat finish.

ALL THIS PLUS THE BEST 2-YEAR WARRANTY IN THE INDUSTRY

Through continuing research Lightning Mfg. has developed a Dual Porcelain Coating that resists corrosive water environments. Now able to apply the same high tech coating to the fresh water series of steel outer lined thus aiding in the prevention cracking and deterioration.

NOTE:ALL LIGHTNING HEADERS ARE BUILT TO ORDER IN 4-6 WEEKS
