The innovative KE bolt-on cast aluminum exhaust header boosts your engine's performance 35-100HP! This unique foundry-tough cast tube style header incorporates four individual water jacketed 32" long runners and easily bolts on to most big block Chevy marine engines, including Mercury Bravo, Speedmaster, and Volvo installations.
This is the only cast aluminum exhaust manifold that could be considered a true header. The runners are computer designed for uniform cross sections and are all 32" in length. The price is comparable to standard exhaust manifolds and the performance will rival double wall stainless steel headers.

"A combination of innovative thinking and high tech casting technology produced a header both lighter and more efficient than we ever expected. Casting a tubular header in aluminum allows them to match steel headers in performance while keeping the price substantially lower." - HOT BOAT, January 1997

do you give a 5 year warranty like stainless marine?

If a guy would bye two sets (four manifolds) What kind of price for black ones. Can I get dry pipes for them. Thanks JOHN

Warranty is three years (3)

Probably out of my price range , but PM it to me anyway

Hi John,

The price is $2795.99 per set of manifolds only. Dry system can be priced out with custom measurements only. Let me know if you have any other questions.

KEPP

Great Header! Glad they are still made

Here is a photo of them on our motors, and then a cutaway from an old proto-type 36" runner version.
