Pipe demensions

I’m being told that there is a measurement from the pipe flange up that requires it to be straight for a specific distance before it bends? Can’t find that measurement in WKA book. Anyone know?
 
I was looking through my 2020 rule book last night and there actually is a rule on that. Big pipes 10in max from top of flange to top of bend, and bottom of silencer can be no more than 9in high when setting on flat surface. Weenie pipe 14.5 max to bottom of silencer.
 
Yes. That rule does exist. My bad. When I read the post my mind went elsewhere in regards to his question. I don’t think WKA (NKA) has that rule like AKRA does. So my response was for WKA rules
