Does it have to be either/or? I am thinking the designer could have picked any angle he wanted then chop chop.
it didn't have to be exact...just kind of a guesstimate. I'm going to be making up my own exhaust with some sort of a turn out like that, and i (the designer) am having a hard time making up my mind between 45 chopped, or a 90 chopped.

No it doesn't, but it is. The designer bent the pipe 45° then chopped off the end at 45°. If you weld a straight pipe to the open end it would be at a 90° angle.
