Lovely! You can't beat a bit of shinola.

I bought a (cheap) set of cored and polished silencers shortly after buying my 900, but chappie had polished off the anodising from the start with a mop and the result is not only hard work for him but as soon as the mop penetrates the hard anodised surface it digs in the ally. They were quite rippled and I could never flatten them out.
I've recently done another set and started with an orbital sander with a flat pad to get the anodise off. This left them flat and polishing was a doddle.
The easiest way to core them if you want to go that way is just to drill holes in the end plate between the inner and outer tailpipe. Much easier than chopping the cans all up, you just keep adding holes until the required tone is achieved.

Chopping boards will be Elm?
