My ERZ gaskets were pretty much Junk. So I went to Subaru today to get OEM replacements. The Gasket they gave me for the turbo side of the pipe doesnt fit like the ERZ Gasket. After looking at the pictures of the uppipe gaskets from subydude.com I saw that the 2 uppipe gaskets that are needed were the same exact 2 that I bought today from subaru. So could I use the one even though it doesnt fit the entire flange?
