Repacking rossier

[Got nads?]

Anybody repack a rossier before, if so how did you get the core out of the exhaust cannister. I repacked it once before but I cant rmember how I got the core out!

i have one for a yfz and i drilled out the rivets in the back and pulled out all the packing and the core is a floating core its not welded it just comes out. the front pipe and the back cap hold it in tight.
