Yeah i agree, but its an expensive convenience feature

I use mine a lot for early morning cold starts as closing the valves makes a massive difference, must be 50% quieter, then after that not a lot and leave it open even with the missus in it.

not sure how its going to be with the MPE.

They're obviously not on the car yet, but my winter tires/wheels were delivered today.

Got them a couple of months earlier than planned, as Tire Rack had a wheel I liked on closeout saving me almost $200!

Exactly.

I have the SST, it makes a difference if you have a the AA DP and the MPE exhaust. When cruising on the Highway in comfort, the rpms are low in 8 gear and a drone is very audible, putting the valve in OEM, the cars goes quiet like stock. The only time I am using cruise is when my wife is in the car anyway. So 99% of the time the valve is 100% open

In that scenario, comfort mode cruising in 8th the valve would be closed with or without a valve controller.

True, but remember. With stock valves even in Sport Plus driving the valves still only open a maximum of 70%, hence that is why some of buy the valve controller. There is quite a bit extra volume in that 30%.

I’m aware but see differing opinions about the sound increase. Some say with the valve open 100% is not really discernible from 70% then others say the opposite. I find it hard to believe it’s that much of a difference. Someone needs to do some decibel readings.

I think it really depends on the exhaust setup one has.

[Lupeskew]

Very true. It was noticeable on my 24 M4 for sure. My wife's M240i was also noticeable but not as drastic but it sure helped.

The SST controler can override any OEM function, mine stays open all the time, unless I either force it closed, which is a bad idea or put it in OEM mode. So the scenario is exactly as I described.

Why would the valve be closed be with the valve controller in that scenario?

SST has four modes, fully open (regardless of car mode); fully closed (regardless of car mode); 50% open (regardless of car mode); and oem behaviour.

I think it may be partly some trying to justify the purchase of the controller, which I can understand. I may go with the cheaper approach and get the $40 bimmerlink app and yank the fuse, again. I want more noise all the time.

$200 isn't a cost I need to justify.

Personally I'm happy with the sound change. It's not dramatic, but then I didn't want it to be or expect it to be. I also wanted the ability to easily change the setting at any time. So it was a no-brainer for me.

At the same time, I certainly wouldn't comment negatively about someone who is happy with the fuse method. To each their own

I’m not commenting negatively on the controller or who may have bought it, it seems like a cool gadget but just being realistic on expectations for those that only want more noise. Is that extra 30% of openness making a noticeable difference? Some say yea, some say no.

The person I quoted said they use the sst box to close the valve when they are cruising on the highway in 8th in comfort mode.

I was simply saying that even without the sst box in that situation the car would have closed the valve anyways.

not if you pulled the fuse

I’ve been thinking about getting BimmerLink for awhile and all of those post have finally pushed me over the edge. $40 seems like a small price for the features the app has available.

Haven’t had a chance to play around with the app. Planning on so this weekend

It’s not a lot of money, but $40 is $40. I already bought bimmercode, and from what I read, bimmerlink is more for diagnostics. Frustrating that you cant have all coding in a single app…I understand this may be possible in an app like Carly.

Oh yeah. That part is frustrating. Could’ve been one app, if the developer wanted it that way.

All this talk regarding exhaust valve control had me curious this morning.

I coded in engine sound menu in idrive a while back and have been very happy but reading that the valves may only be opening up to 70% had me check via BimmerLink.

With BimmerLink connected I put the car into “sporty” sound mode via idrive. I heard the valve open. Then in BimmerLink I set the exhaust from auto to open. The exhaust valve made no noise. I played around and could control the valve via BimmerLink but it appeared the valve never opened further than the idrive “sporty” setting.

So am I right in believing the sporty engine sound menu opens the valve to 100%?

It was always my impression that bimmerlink could only open the valve to 70%.
