But sound wise, PE is superb! Try do some other modifications to go with your PE, such as BMS PBX / AA Tune, a high flow filter / air intake system, Okada plasma direct coil pack, etc. I believe the outcome will be nice for our N52 engine!
What is AA Tune? any idea how is the bmw performance air intake?

if our cars come with sports muffler stock then why does it sound like a pussy?
there is no stock sound at all.
Is no 20 in diag the flap valve you talking about? this is my exhaust diag i got from real oem.
