45. Muffler direction reversing adapter

For now, it's in shape.

Twist 60° and weld the pipes together.

It took me a while, but two parts completed.

Work on the other.

Overlap the gasket, drill a hole for fixing, and you're done.

Draw a line according to the shape of the muffler flange and cut the unnecessary part.

I bought two because the scaffolding base of the single pipe seemed to fit the purpose.
