i removed the left heat exchanger to replace the oil return tubes.and the exhaust pipes are stainless steel and the outer sheetmetal is steel.is this an oem heat exchanger?the exhaust pipe,flange to head,gasket is stainless(new ones).are the new gaskets reusable? -- thanks--

 

I be lying if i said i hadn't reused some gaskets, but only if they are perfect. They are cheap. No, really, they are. Another tip, Wurth has copper nuts that will not seize and cause you to break a stud, or even if they do, one tap with a chisel and they come right off. A local Porsche shop (Fruitmair in Kitchener, Ont.) told me this years ago, and it works!

for my car OE gaskets are copper clad, so I'm not sure about your SS ones.
