I invested heavily in various tools when I went to remove the OEM pre-cats and that 13mm stubby worked great in tight places. For future reference, the upper 2 bolts on the downpipes are accessible from the top with the upper plenum removed. Working around the master cylinder can be a little challenging but not necessary to remove it.
