Pre 2009 i think its a 2007, the silencer is welded all the way around, what would i use for the packing ?

Hi all, just started getting a really noisy exhaust on my 4RT, there's no leakage on the joint between the back box and front pipe just from the tail, I assume its going to be a new back box but just wondered if there's a fix, thanks in advance Simon
