For what it’s worth on the bark box, I had one come apart on a saw I bought used. The welds cracked. I put a Jason Egan muffler on my 462 and it’s loud AF, but woke it up some. I did put the WCS fallers kit in it and it helped stiffen things up a little. I use the 462 the most since it is light and powerful. Hope you are enjoying it!
