Light aircraft exhaust systems and turbo prop exhausts are fabricated from Inconel. These have high concentrations of nickel and steel. It could also be part of a recip-engine manifold, which in many cases-unlike car manifolds-are tubular and individually routed a short distance to the muffler system. At 10 pounds however it's unlikely to be part of the exhaust pipe of a light aircraft-but possibly part of an older radial engine design, ie DC-3, some sort of a Warbird.
