Mild steel vs Stainless steel exhaust gaskets

Im looking to throw on new gaskets when i take off the headers and up-pipe to put new heatwrap on, seems like mild steels ones work out at about 10 euro each whereas the stainless steel ones come in at about 28 euro each! what advantage would the stainless steel ones have? New gaskets were only put on about 20k ago when i go the engine re-built(not sure if they were mild or stainless) but is it best to replace them and not re-use them? Where's the cheapest place to order?

Ill need:
top and bottom up-pipe gaskets
manifold gaskets
downpipe to turbo gasket

All twinscroll fitments

Better of with genuine subaru

Other ones are not available but try davelegacy or Ali burrows think they carries them all in stock

the one i was looking at were genuine on there aswell Baz, they just have old and new style it seems. i need to shop for impreza bits now since i converted to the sti twinscroll setup. legacy twinscroll flanges are different

I can't tell if ur being sarcastic or not

Ha no.

The stainless ones be better gaskets

Stainless will take the heat much better and will withstand corrosion way better
