Hear me out (exhaust help)

[wainwrightj]

Re-Starting this thread rather than making a new one with more exhaust problems. I recently bought a Scorpion back box as I really like the look and sound of them compared to the OEM one. I tried to install it and noticed that that flanges from the centre box match the flange from the scorpion box which means they don't fit. I don't know if this is my fauklt for buying the wrong box or if the exhaust somebody put on is wrong and they welded new flanges on the make it all fit together which is what it looks like has happened.

   

I've tried to draw a diagram to explain what I mean but basically is the centre box meant to have that type of flange or has it been changed?
