Was that intentionally cast that way or was it a Friday cast?

462 cyl, the port exit is cast like that

462 cyl, the port exit is cast like that

I have to ask, why?

What’s the benefit of it?

Spin the exhaust gasses, vortex design....LOL

I guess after a day or two of repeated/redundant questions, either the Monkey or Tree Life, since he seems to know of this ‘design’ might chime in...

I do like the cyclonic, vortex theory though...generally on the intake side, but what the hell...this could be a new-fangled game changer! Lol

nobody knows

Stihl is well known for their ,beer- gineering, swear sometimes they do it just to prevent parts swapping between models, keeps parts exclusive to Stihl Corp, slows up the China copies.

Can't blame them there. Nothing like putting millions into R&D just to have China buy 1 saw, copy it, and sell it at discount prices and ignorant consumers eat it up.

Patience...just a matter of time!

I know that before I retired that most of our lab test results showed a significant increase in power and performance on engines if the intake was designed so that the air/fuel mix was more volatile. Exhaust showed better flow the smoother and symmetrical the exhaust port was.

I dont see any advantage to the rhombus shape of the exhaust exit, then again I'm not a 2 cycle engine engineer/designer.
