seadoo help

Hey guys I had a few questions, I purchased a 1996 seadoo hx works great but the exhaust manifold cracked on me and ive been trying to track one down, does anyone know if there’s any place that sells aftermarket exhaust systems or does anybody have and exhaust manifold with the part number 979 141?

Ok, Maybe someone out there in computer land can help, I have a 2005 Seadoo 3d with the Rotax 782, last year while thoroughly enjoying my ride, unknown to me the battery strap had worked loose and my battery spilled over onto my block knocking my oil resevoir line off as well as breaking 2 brass...
