Well my new 335is is here and I'll be doing it again. Never had any trouble before, enjoyed the noise. We do need an E93 and newer sedan walk through though from the sound of it.

Important to remember that this is a tiny little "tweak" really, it's only about noise, there will be no increase, decrease, etc. It might sound faster...

This is awesome.. has anyone taken it a step further and wired it up to a single/double pole switch up front to turn it on and off quickly and conveniently without having to go into the trunk?

Did the harness have to be zip tied down or did you guys just leave it hanging there?

easy literally 1 min process.
cold start is noticeably louder,

probably in my head but it feels a loss of power...

Did it today.. No error codes.. Not a huge difference but notable difference in start up.. Not sure what the big fuss is all about.. Cool stuff and I don't see why this will hurt car's performance.

Hey guys I'm new and got a 08 e92 335i a coupes of weeks ago. My exhaust rattles a little bit on startup but damn it is loud. My dad has a 10 m5 and we were looking at somthing as easy as this to make his exhaust louder but we couldn't find anything so I just decided to try it out since its so easy to do. The first time starting it up with it unplugged there was zero rattle from my exhaust at all. Maybe that can tell me what wrong with it normally but so far doing this DIY has already fixed some things and it makes it sound so much better!

Most rattle you here through the exhaust on startup is the waste gates. Do you only hear the the rattle on cold starts?

What a thread! This has been a very entertaining read, and a socio-psychological rumpus as well! I love the posts by those who confuse correlation with causation: "I unplugged my actuator and it started raining. When I plugged it back in, the rain stopped!"

Just one data point to add... I've had mine unplugged for 4000 miles, and amazingly these are the consequences:

The exhaust is louder
My engine has not been destroyed
My cats did not explode
My tailights did not go out
My dealer did not void my warranty
My car did not fail emissions inspection
My car did not gain or lose power

I must be the luckiest guy in the world - I beat the golf tee Gods! Man, I should go get a lottery ticket!
