2007~2015 Exhaust Tips

:
2009 Mazda CX-9 GT
Has anybody changed the exhaust tips on a 2007-2012 CX-9? The ones with the ugly trapeziodal tips? Looking at changing them to a single or dual round, but based on the size of the notch in the bumper, dual may be the better choice. Thinking the tips need to be angled to match the curve of the bumper.

I think Mazda changed to single round exhaust tips in 2013 if you want a factory look.
