AirHeaded - Ah-8-Tee - Exhausted

First time on the Ah-8-Tee that I have tried to remove the exhaust nuts so I put anti-seize on the threads.

Used exhaust spanner.

Right nut comes off no probs. Left nut. Even using a hammer on the spanner the nut wont move. Looks like in the future I will be cutting that nut off. Wish whoever did the maintenance on this bike previously had applied anti-size paste to the threads. FARK!
