Stoo.c said:I think one of the biggest issues is the quality of materials in these 'cheaper' versions. Clearly the flange on that manifold isn't stainless regardless of what they may say and often they use sub standard 'stainless' steel which still corrodes very quickly as you have witnessed. The cracking of welds usually comes from using very thin metal to get the costs down however the way the Porsche manifolds are supported means they are not under a great deal of stress.
I do alot of work with old B series Hondas and the manifolds hang down with all the loading pretty much up at the flange and I wouldnt even consider buying a cheap manifold as they crack horribly.
