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

What year? Up to 2009ish they were a 1 piece silencer, which could only be re-packed by cutting it open, re-pack, then weld back up. After 09ish they were pop rivited together and can easily be split and re-packed. 

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