MS462 exhaust cracked

[Donnie]

Well then. I’ve been running a bark box on this 462 since about December. It’s only 6 months old.

 

I’ve cracked the inside of the exhaust it seems and the guy at the shop reckons I’ll seize it running it with it being cracked. 
 

New exhausts the best part of 100 pound and I’d just rather not pay that if I don’t need to…

 

Just looking for a second opinion on what the fella in the shop said. Not doubting him or anything

I think this might of been better just sent directly to @Crocky as I’d imagine he’d know 😂

Odd for sheet metal to crack in that way. Exausts would not normally be a hardenable steel, and so should bend before cracking, unless its stainless?

 

You risk bits breaking off and getting inside the exhaust port, Im not sure how else it would seize.

like the husqvarna 585/592 Stihl went for max weight saving which is ok until you stick a heavy barkbox on the front and you expose a weakness. The 585 which runs a little faster than the 592 seems to suffer a few problems with cracks so I'm guessing this is a similar problem ?
