Just noticed the bolt (presumably) holding on my exhaust link pipe has sheared off,

Is my only option get at the broken stub to remove the whole exhaust?
While I have no great worries about riding it in the short term as it all seems secure enough,I will fix it,but if I have to disassemble all the pipework then I'll wait for a 'slow' day during the bad weather.

Was there a washer on that?(didnt fit it myself y'see)
