After a few days with the exhaust, here are some additional observations:

Cold starts sound much better (although the stock system was no slouch in this regard). Upshifts using the paddle shifters sound, in a word, glorious. No drone detected thus far when traveling 60-70 mph on the interstate. I find myself driving with the windows and radio down more than ever before. Exhaust sounds relatively tame in EcoPro mode.
