Melrose C6 Corvette Monster Flow Smooth Flow Ceramic Coated Long Tube Headers

Engineered by the same team who produced the headers for the LS-1 spec engines that went into every ASA racecar. These headers, named ?Smooth Flow? as result of their having no sharp bends or restrictive welds, are constructed by hand to the highest of standards. Headers are constructed using 1 3/4" aluminized steel primary tubes, 3/8? thick CNC cut flanges, and 3? collectors.  They are finished off with a lifetime warrantied inside and out Jet-Hot ceramic coating.  Look for huge power gains from the best fitting and performing Corvette header on the market in an easy to install package. 
 

    Handmade in the USA
    Easy bolt on installation (Headers install from underneath with no engine lifting)
    Outstanding torque and HP gains

What purpose does the ceramic coating serve?

Ceramic header coatings serve a multitude or purposes- Most importantly it is protection for the header and the car. On average, ceramic coated headers operate 30% cooler than uncoated headers. Hot Rod Magazine said this about ceramic coated headers "...ambient temperatures with a heat gun in the vicinity of the headers did show a 200-degree-F temperature drop near the pipes at the pipe surface. Although the dyno numbers don't reflect this drop, in a tight engine compartment, a reduction in exhaust-radiated heat could translate into a big power gain: On a normally aspirated engine, every 10-degree-F inlet temperature decrease increases engine power by about 1 percent. Even if the air were only 50 degrees cooler by the time it got into the inlet tract, that's a five percent improvement."

Will installing headers help my performance?

Most definitely! Customers that install our header, x-pipe, and hi-flow cat system see exceptional average gains of 37-38 HP and an avg. of 35 ft. lbs. of torque

Are your headers stainless steel or mild steel?

Our headers are constructed of aluminized low carbon steel, or in general terms, mild steel. The more carbon a metal contains, the more susceptible it becomes to fatigue and cracking. In summary, stainless has a very high expansion rate as opposed to carbon steel, which gives way to premature fatigue on the metal and the welds due to the constant growing and shrinking of the metal. Stainless also radiates a lot of heat in comparison to ceramic coated mild steel. Heat sensitive components like spark plugs and wires, electrical parts, water pumps, and many other critical engine components can fail due to premature wear and fatigue from prolonged heat exposure.

If headers are so efficient why aren?t they installed at the factory?

Auto manufactures install exhaust manifolds because they are cheap to produce, take up little space and have a higher margin for error in manufacturing. All of this comes at the expense of performance with poor flow characteristics, heavy weight and unbalanced exhaust pressures. Headers require more precision and craftsmanship in manufacturing but they are rewarded with smooth tuned and balanced exhaust flow allowing air to travel through engines more efficiently with the less restrictive backpressure. With Headers, each exhaust port has an individual primary tube that merges into a common collector. The balanced integration of dissimilar firing exhaust pulses generates a ?scavenging? effect that increases exhaust flow and balances back pressure in the cylinder heads allowing the engine to make more power.

Installing exhaust headers is an essential step to achieving the potential out of any high performance engine. If you are building up your motor, headers should be at the top of your list. Headers are the most cost effective upgrade in performance that you can make and will enhance most other engine upgrades as well.

I have heard I shouldn't dyno my C6 directly after header install?

This is true. When the battery is disconnected the vehicle loses it's memory. The car should be driven at least 88 miles with 15 starts and stops. If the battery was not disconnected during install, disconnect it before this process. This will clear the fuel trims and allow the car to learn faster.

My friend installed a pair of headers on his car and they hang down quite lower than undercarriage of the car. This caused the headers to drag and scrape on the ground under normal driving conditions. Will your Smooth Flow headers do this?

No they will not. In fact some of our most devoted customers are racers with very low ride heights. Ground clearance is always a main concern during design.

Will the Jet-Hot coating stand up to racing conditions?

Jet-Hot claims their sterling coating we have our headers coated with will withstand temps up to 1300 degrees. To put that into perspective most aluminum alloy pistons melt at approximately 1,100? Fahrenheit.
