Manifold Kits: "E-Coated" or Ceramic, OEM or Aftermarket?

[ThndrSki]

If you look at mercexhaust.com, they have exhaust manifold kits that are "E-Coated", and they say they are fine for Salwater over the Ceramic Coated ones... anyone have a feeling on this?

Also, is this the cheapest place to buy a whole kit OEM? I really would like to stay OEM as they lasted a loooong time. I know $528 compared to retail OEM is no question...

Also, if anyone has thoughts on Aftermarket, please feel free to join in... Not sure I'll ever purchase, but ya never know.

Thanks!
