Weird sound (pops) from the exhaust
When in park with engine idling. I revv it up to about 2000 RPM and sharply let the throttle off. While RPMs go down I here one or two subtle pops from the exhaust. Is it because of misfires? What is it? Is it normal?

Could be the wastegate on the turbo. This is a common noise on 335's and I hear it on my 335 when I am decelerating especially at slow speeds (manual) and let off the gas. I'm no engineer but I did stay at a Holiday Inn last night.
