Hi all, quick update from Sweden.
I'm SUPER HAPPY with the end result after installing the Active Valve Control from Active-Sound.eu yesterday. Now I finally hear the potential in this car, it has a deep tone and is much louder during low RPMs. I can no longer cruise unnoticed on the streets apparently (if flaps are open). Another thing I need to mention is also how quiet and comfortable the car is when the flaps are 100% closed. Videos are coming, just need a tool that lets me blur my license plate. Any advise on software I should use?
Yes, I paid a higher price for my unit. Yes, I needed to "hardwire" and cut cables in my trunk - but it's worth it with the security features this module has. Even if my flaps are closed 100%, they will be forced open at high RPMs. The installation took about 20 mins.
I'm still waiting for my MB dealer to get back to me in order to get the latest software to get some loud crackles. I can't wait.
Please make sure the unit you are mounting has the same features, in order to not cause damage if you end up driving hard with the flaps closed.
EDIT: The perks (and reason it's more expensive than competitors) of the Active Sound version is that the exhaust button in my car still works, and it has the security feature mentioned above.

Exactly, same here but they listen once you use brute force. Do you live in the US or Europe? I have the software version you need if you’re located in the US. Happy to send!

I’m told since the ASR doesn’t force open the flaps (if closed) >4000RPM it can be harmful. I may be misinformed.

Yep in the US. Send whenever you can, trying to build up information to take to them next time I do.

All of these modules open up valves 100% regardless of mode for safety at higher RPMs. I’ve yet to see any that aren’t programmed to do so.
Also, the OEM exhaust button will still work to some extent because the 3rd valve located on the H-pipe operates dynamically based on what drive setting you’re in. So it would be advisable to keep that button on for maximum volume and pops/cracks in Sport+ and Race!

Yes, I do think back pressure could cause issues if the valves are forced shut under load at high RPM. But I don't think that is a concern because these boxes are programmed to open at high RPM regardless of mode. Personally, I would only switch between the fully open valve mode and the regular OEM mode where I can use the exhaust button to switch the valves. I don't like the idea forcing the valves completely shut, I'd rather run it with the OEM setting with the exhaust button off if I want quiet.

When ordering the ASR module you can select the 'Startmode' you want. They program the unit with your preferred mode before shipping.
Before ordering this unit, I emailed them for some extra information about these Startmodes and this was their answer:
The SERIEN MODUS is what I believe a modus where the ASR module disables itself so the exhaust valves function like as with an original vehicle without valve control unit. If the factory exhaust button on the middle console still works? That I don't know...
I ordered my unit with Startmode "Sport Modus" and if someday I would like to reprogram the startmodus with another modus I would need to select that particular modus and (quote from their email):

The selection is for the start mode.
That means, how the flap control should start.
Letzter Zustand --> last mode you activated(memory) Komfort Modus --> flaps closed at start Sport Modus--> flaps open at start Serien Modus--> flaps are in original position (flap contol deactivated)

you can change the start mode by yourself.
You need to press a button more then 10 seconnds. Then it will use this mode as start mode.

Hi, I'm new to the forum but I've been following this thread for a while. You shouldn't expect an answer today and/or on Monday as both are bank holidays throughout most parts of Europe due to Easter.
I am a quite new owner of the C63S and I love it. But, I doesn't have the sound I expect from an AMG. Even though my car is equipped with the performance exhaust it doesn't give me enough AMG feeling. Hence, I started researching and found this video:
this video on Youtube
It basically tells you the exact version of software for both the engine itself, and the gearbox. Great I thought!
But, after extensive calling to authorised dealerships around Sweden (where I live and the car is registered) they told me this software version cannot be fitted in my car due to EU regulations & the fact that they can't "choose which software that goes in my car and gearbox" and/or "retro-fit old software" into it. Major bummer.
After this, I went on to do research with different non-Mercedes-authorised tuning companies. No luck here either.
I finally then found the Active Valve Control stuff, that according to this video (already posted above, I know) from the seller CAN MAKE IT SOUND BETTER:
this video
I've emailed the guys now, expecting an email back Tuesday next week or I'm giving them a call. I really, really hope this will give me what I want. Is there anyone on this thread successfully mounted a mod that ensures 100% open valves on all RPM's?
Thanks in advance guys!

Hi,
our flap control dont need to be connected to the can bus! That is really important for mercedes warranty, beacause with the other flap control you need to damage the can bus cables.
That is the reason we made a flap control with a transmitter, so you can install within 2 minutes without a connection to the can bus.
Our control unit doesn't open the flaps automatically. But you don't need this function because you can use the „open mode“ and the „original mode“. We can also sell our control unit only with this two modes: „Open“ and „original“
With the other flap control you need an automatically open because the cars starts every time with closed valves! The is a big disadvantage and the user need to press the button after every start.
Our flap control has a memory function and starts with the last mode.
When you open the flaps with our transmitter the button in the middle console doesn't change the position. When you activate the original mode, you can normally use the button like without our flap control.
I hope you understand the advantages of our flap control and i would be happy to if you can share these informations.
Best regards
Mit freundlichen Grüßen

I wil try and get one together, but really the best way to describe it is to say it's the same loudness/depth of sound as a completely cold start, but all the time. The bangs and cracks on shifting and sudden throttle lift-off is louder to my ears also.

Yeah I’m hoping it makes it a little deeper and more burbling at idle or parking lot speeds

Daniel, thanks for coming on her to clarify things. A couple of questions:
1) How to you select the "Start Modus" ? Do you have to open the trunk and change a button/setting on the module in the trunk? Or is this something done via Bluetooth on your phone? Or a remote control?
2) Based on your answer to Question #1, if I want to turn on Original Mode before I turn off the car, and want it to stay quiet when I start up in the morning (to keep it quiet for my neighbors), but then want to change to Sport Modus to keep it loud while driving, how can I do that? Do I have to stop and open the trunk do make this change?
Thanks!

I have received my unit but still need to install it...
Does it take long to reach the cables in the trunk or do you waste half a day by removing the inside of the trunk interior?
Also when installing the ASR can someone confirm if it will leave flags inside the ecu when the dealer connects to it through obd2? Maybe the MB car system senses that there is some kind of 'override' on the exhaust flaps and triggers an internal error?

I think this would work perfectly with some high flow cats (I hope it's loud enough haha). Kinda hesitant to go catless just cuz of the smell (used to run full exhaust on other cars and it was pretty strong...like NO ONE wants to ride shotgun lol)

It's awesome to see the updated ASR module is literally one plug intercepted in the trunk (as opposed to two plugs on the actual exhaust flaps), so the install will be super easy... around 5-10 minutes.
I really don't like the way the M177 sounds with catless downpipes, you lose that nice engineered deep AMG rumble and instead sounds really raspy and raw (not in a good way IMO). Not to mention the smell, I had catless DP's on my B5 S4 and it stunk! Besides, the gains you get going catless on the M177 isn't worth the trade-off in sound. If people were picking up 35-40 HP to the wheels, that would be a different story... but I don't think 20-30 HP to the crank is worth de-catting.
I think ASR + the secondary cat delete would be the best sounding setup for this car. Personally, I'm leaving the cats alone and will just be installing the ASR.

IMO the downside with the ASR module is you need a remote. I find myself closing the valves often enough that having to do it via the remote would annoy me. I would prefer to use the exhaust button to fully open or fully close the valves and also have it respect the valve open/closed based on driving mode (Comfort/Sport/Sport+). I don't mind tapping into the wires in the trunk to do it (my car is just out of warranty). But the Active Sound Module is to expensive at 429EUR plus 55EUR shipping. Is there another brand that works the same way but cheaper?
