Yes, did it to mine. If you dont like it you just plug it back in.

It throws 1 code, however they (BMW) does not care, and or if for some ungodly reason they do, it could've "come loose".

Have had my car into service several times and seen the code on the screen and they dont mention it at all. Love it.

With you in it

derin11 · 01-28-2010, 09:40 PM

i unplugged it and can instantly hear a difference at idle, its louder for sure. I can always clear the code just incase with my bt tool

Marcadelic · 01-28-2010, 09:56 PM

Ya i did it, love it, louder in every aspect

NiVeDh · 01-28-2010, 10:07 PM

It works. Very noticeable at cold startup. Not so much during normal driving.

Spoolin335 · 01-28-2010, 10:12 PM

i have mine unplugged, i also have a aftermarket exhaust so its pointless.

JerzeySux · 01-29-2010, 01:24 AM

Stay near your driver side exhaust and unplug it you will hear the exhuast open up and notice the noise and smoke coming out in idle.

Shieldze1025 · 01-29-2010, 06:03 AM

Did it last night, took about 15 seconds. I do like having the full exhaust all the time now though.

bavarian19 · 01-29-2010, 06:09 AM

I dont get the point. During a cold startup, it closes, but doesn't it open up anyway after so long?

I thought it was used to heat up the cats.

Can you save me the search time and give a link or product name for the "bt tool". I have a 2010 E93 if there's a difference.

frans335 · 01-29-2010, 10:34 AM

So, help a newbie out. What is the point? It goes from single exhaust to 2? Thanks, sorry if this is a dumb question.

The left exhaust pipe stays closed for the first 30 seconds after you start the car. This unplugs the actuator which disables the valve, therefore keeping both pipes open all the time.

I believe this is correct, it keeps it close to heat up the cats faster. Can anybody comment on this?

JerzeySux · 01-29-2010, 01:44 PM

I didnt know it only closes for the first 30 sec. I thought when you unplug it it stays opened all the time VS plugged the exhaust will be closed on left side until certain amount of throttle is given. Am i wrong? Also when you see 335's on the road and look at there left side exhaust you can see and metal flap closing it until RPM changes and gas is given. That what i thought.

continentalg5 · 01-29-2010, 01:48 PM

Yes it works, I liked it for a while, but I started getting exhaust drone during highway driving so I reversed it.

Def makes it louder.
