This item is bare metal made from a casting with little or any detail of the molds! Doesn't sit level On my work bench, I will have to take a grinder to it! The product is made in the USA which makes me sad ! I would only hope they go to a plastic and a more detailed version. I'm a retired welder / Pipefitter so I think I know a little about about welders. These are not even close, Exhaust then two air intakes? Not even close. Waste of money, also the the casting seem goes completely around The mold looks terrible! I'm melting mine down for shark fishing bell anchors!
