In pandas DataFrame are always columns, here if need remove first level use DataFrame.droplevel with DataFrame.rename_axis for remove index and columns names:

df1 = df.droplevel(0, axis=1).rename_axis(index=(None, None), columns=None)

If want write DataFrame to file with no header:

df.to_csv(file, header=None)
