Exhaust for 43mm bolt spacing on Frankenstein

[DieselTech]

I think your easiest thing to do, would be to make you a steel exhaust flange that fits your stihl exhaust port & have someone weld it to your pipe for you. I could make a no weld adapter, but I'm unsure how to explain it.

Off topic a bit here, but is that aluminum intake adapter pressed on to the stihl cylinder intake port?

Thanks for looking. Our regular mechanic might be able to recommend someone.

I'm looking into buying an MS660 Stihl Frankenstein off Ebay. The exhaust has 43mm spacing and I'm having a heck of a time finding anything that'll work. I'm looking for an expansion chamber m65 clone if possible.

Use a washer of the right size hole and drill the stud holes in it where they go, then grind it to the shape you want and weld the flange to the header.

Thanks, hadn't seen that one yet
