theres a cheap #### manfiold and a cheap not bad one i got one 250 show polished 3.2mm thick cant fault it if its high mount brace it to the brace but shouldnt need it just brace the runners to the manifold plates the manfiold cant be braced it needs flex and will have massive amounts when stainless is hot. just keep an eye out theres a place called n power on ebay their ones are mad might be able to get high mount
