I miss that sound... Now I have everything stock after the headers and there is no noise at all, basically sounds stock.
I gave my PE to my brother for his E90, felt bad only using half of the exhaust, looking to get SS exhaust now.

Wait. So you're saying that stock headers + stock secondary cats + PE catback (no resonator + PE muffler) is LOUDER than catless headers + stock secondary cats + OE resonator mid-pipe + PE muffler?
If so, I'm very surprised that the OE resonator has more sound attenuating properties than the OE catted manifolds.
