Hi aj, I have this same exact exhaust and mine fits fine.
There are 14mm (I believe) bolts on top of each of the tips. You can loosen those and you can adjust the tips until they fit perfectly. Don't forget to torque to 30 ft/lb
If that isn't the problem, try adjusting the clamps on the right hand side of the exhaust.
But if it's truly an issue with the hanger, none of these will work.
