Downpipe to mid flange angle

I'm having a local shop fabricate a cat delete for me to hook onto the end of my Xforce DP and they need the dimensions to make the pipe. It's a bit hard for me to take my car in to them so they can just chuck the Xforce DP on and measure directly from that - I drive out of town for work every day.

I know the length that the pipe will need to be but not the angle of rotation that the flange connecting to the mid pipe will need to be. The end flange of the DP sits on the horizontal (the two bolts line up on the horizontal plane) but the mid pipe flange looks to be rotated about 45degs anticlockwise off of horizontal.

Does anyone know what angle this is? Maybe someone has a DP or mid pipe lying around that they could measure?
