Is there a trick or special tool to access the bolt that holds the header pipe that resides under the oxygen sensor to remove the header pipe so I can install my Malossi Exhaust?

Haynes manual suggests dropping the engine or completely removing all the panels including the floor panel to gain access. I can not seem to get at it from underneath while on the kick stand.

Got it - Thanks for the messages. 6" 1/4" Wobble with 10mm Socket.
