I need to remove the silencer from my motorbike but the join to the next section seems to be immovable. Advice and guidance sorely needed. Only fly in the ointment is that the non-silencer half of the problem contains a catastrophic perverter which may not respond too favourably to excessive brute force being applied in the form of hammer blows in its vicinity. FWIW the bike is an R1150GS TIA Richard
