HEDMAN 304 Stainless Steel Hedders

Hedman Hedders has been putting together its world famous headers using mild steel tubing and flanges for more than 50 years. Although Hedmans are extremely durable, the mild steel material used by all header manufacturers is no match for the harsh conditions of an engine compartment. Even coated headers will fall victim to environmental conditions over time. Hedman 304 Hedders virtually neutralize the power of nature and the heat of the engine compartment. Built entirely of type 304 stainless steel (flanges, tubes, collectors), Hedman 304s are considered "the best of the best". As this video states, the 304 stainless steel used for 304s withstands heat better, and resists corrosion far better than mild steel materials. All Hedman 304 stainless hedders are available HTC (ceramic-metallic) Coated for vehicle owners who prefer a polished look in their engine compartment.

Jeep CJ7 Laredo 304 V8 Open Headers
Just installed new Hedman Hedders on the CJ. Taking it to the Exhaust shop tomorrow to have a custom built dual Exhaust system installed. Thought I'd crank her up and let you have a listen. Got the new Exhaust installed today. Consists of Hedman Hedders (3/8 in flange with 14 guage tubes), cross-over pipe, and MagnaFlow mufflers. I've found that a new dual Exhaust system's sound will become deeper and more mellow with time. It takes a while for it to get broken-in. - AMC 304 V8 Bored 30 over. - Mild Cam: http://www.summitracing.com/parts/SUM-8600/ - Hedman Hedders 99208 - Edelbrock 500 Thunder Series Carburetor - Edelbrock Performer Intake - Performance curved HEI distributor from performancedistributors.com - Spectre Air Cleaner
