Actuator exhaust valve plug?

OmidHariri · 09-09-2013, 12:54 AM

Today my friend told me that his 335is and his friends 335 had these plugs behind the left tail light that if unplugged makes the car louder. I did research and learned its the actuator valve plug that 335s and 330s came with.

Is there any effect to unplugging it? I unplugged it and idk if i actually heard a difference. I thought it sounded louder but idk ive never really heard my sound because its stock. But what are the pros and cons to this and does it really make it louder?

Provide pics! I wonder if the 328s with N51s have the same deal.

I have a 330 with the actuator unplugged. No difference if you ask me.
