Any info would be great...they look good but not sure about the no name headers

It doesn't look like they're water jacketed? I don't see any bungs for water connections

read the ad they are water injected not water jacketed . No good for ur application

In case the OP or someone else doesn't understand what we mean, water injected is SINGLE wall and is illegal (not CG approved) for use in a enclosed engine compt. These are jet boat headers, the water is mixed directly into the exhaust stream right near the exh port as a mist and cools them just enough to keep them from glowing cherry red, I personally know a fellow osoe'r who went as far as to buy a set of these thinking they would work on his baja he was selling but I won't mention RANDY'S screen name. He sent them back no problem but their ad IS very confusing as it mentions offshore boats specifically, Smitty

Will work if you dont run an engine hatch..
