Welcome to the club! I've had my PPP for a month now (two weeks for delivery, don't know why you had to wait so long). I think it's a bit unfair to complain it's too loud. I think the posts I read on here where right, the exhuast IS louder, but not anything like as loud as most other aftermarket exhuasts. IMO at least it now sounds like, looks like and drives like a sports car.
Just enjoy it, it's really not that anti-social.
