Anyone use the CETE active valve controller?

[arrivalanche]

Like it says, Im looking at this module to get some more rumble. Anyone use it? I need some unbiased opinions here. For $550 it better be amazing.

[mariokart]

This comes up a lot. Just unplug the valves when the motor is off and they will remain open all the time. Saves you $600

IMO doesn't seem worth it. Now if there was a module that allowed you to control cylinder deactivation, I'd be all in.

There is a free, no cost solution for this that only takes one button push

Its totally pointless module, don't buy it! It does not make your car louder, only lets you control the valves (close them if you have stupid neighbours who complain that your cars exhaust is too loud for their ears)

A lot of misinformation in this thread.

OEM valve behavior
dynamic - valve stays closed until 3-3.5k rpm then remains open (I find this insanely annoying to go from dead silent to a huge rumble under normal acceleration)
comfort - valve stays closed until 5k rpm then remains open (also annoying)

These behaviors make the car feel and sound very odd, and the acceleration nonlinear in terms of sound.

The Cete module behavior:
dynamic - keeps valve open at all rpm, makes acceleration sound and feel linear and the engine noise remains as rpms increase
auto - oem behavior
comfort - keeps valve closed at all rpm

Also by double clicking the ESP, you can instantly either open or close the valve

I agree it's expensive for that type of fix but if you can find it cheaper (I did), it's worth it to me. Maybe I'm too OCD for my own good but it's worthwhile under $500

Aaron, PM coming your way.

does it throw any codes? Never thought of this...

do elaborate.

Pricewise it all depends if it is worth it for you offcourse, high price for what it actually only does (when the car should of simply come with a dedicated exhaust button).
I'm catless non res milltek, for me it is worth every penny. Beside the true dynamic/comfort setting, i do often use the button. City driving closed, open road...open and enjoy :).

[Logtec]

My Friend has this module, he hates it, total waste of money, it didn't do anything for the sound, everything is the same as before. Actually in dynamic mode the valves are always open, its not true they open around 3k RPM.
And if you just unplug, there will be no fault codes, I have the supersprint mufflers, just took it out and taped the wires.

I'm more or less in the same boat as you. my original setup was apr downpipes with a non res valved miltek exhaust. Cold starts shook the entire neighborhood and draws too much attention sometimes when trying to fly under the radar. I replaced the non res section with a res front section from miltek and the car does sound fantastic but a little too OEM for me. I want to put the non res section back in but not at the expense of the noise when i dont want it, how drastic is the volume change when switching between comfort and dynamic? does the exhaust still have a "nice" exhaust note when closed or does it rattle?(my b8 and b8.5 S4 with valvsonic exhaust would rattle the valves when closed). i have been torn and going back and forth on this for quite some time now.

Sound is offcourse an individual taste, i love the combo and actually adore the comfort sound. It has a soft 'hgggsss' sound where as valves open is...well once past 3k rpm it is...you know and maybe too much (luckly the cabin is good isolated :p).
If wanted i can try some sound clips but you know, cellphone quality but it would give you an idea. Non res with open valves = straight pipe.....and the reason the module is worth its money for me.

[Dasquade]

Forgot to adress the rattle....
Maybe i got used to it, but since going catless i do get a lower metalic rattle note (witch was more prone in 4 cylinder modus). Still bit unsure if it is/was the wastegate valves we hear (they do rattle bit when engine is off when i placed the dp's, seams to be normal). Maybe cat related...anyway, never experienced exhaust rattling flaps. Even the other way around, my left flap from time to time starts to get stuck. Reason is the stock spring in the actuator isnt pushing down hard enough the flap and flap gets stuck behind the lip in exhaust. Maybe that is an new 'feature' on the current millteks compair to your s4 milltek. Fact is, oem exhaust doesn't have the press-turn design.

Not getting the feeling its worth it. I guess Ill just X-pipe it

[Ze_Nardo6]

Different purpose. The module doesn't add sound, the x-pipe will

[richib86]

the module is really more for the cars that are already loud and need to tone down for whatever reason

[Dasquade]

Exactly :), quiet sleeper & animal at the push of a button ;). Again, unless you don't really really needed for most it will be an overpriced 'gadget/feature', for some it is the perfect OEM integrated solution.

The module is not designed to make the car "louder". The module is to allow you to control the exhaust valves in a more sensible and on demand way.

For a user with an aftermarket exhaust that is considerably louder than stock may want the ability to have the valves closed completely on startup to not wake the whole neighborhood up in the morning or late at night coming home. When you get out of ear shot of your neighbors to then double tap the ESP button and get instant open exhaust valves all the time.

Not keen on a police officer paying too much attention to your loud exhaust, double tap the ESP button again and quiet the car down on demand without adding a separate keyfob.

Thats what I'm trying to say, It won't make your car louder like some here are talking, it just makes possible to close the valves on cold starts if you have angry neighbours. Completely pointless toy if you have OEM exhaust.

[Ze_Nardo6]

No one here is saying the module makes the car louder..

An x-pipe is not a substitute for the module. Serve completely different purposes.

[Alex@Europrice.us]

The misconception for some is that this will make a stock exhaust magically louder and it doesn't thus making it useless and overpriced. It is useless for making your stock exhaust any louder than it is in dynamic mode when the valves open.

It however is very useful for customers who have aftermarket exhausts who need or want direct control over the valving for specific situations. It makes valve control easy with the MMI or the double tap of the ESP button for instant control without having to use a separate keyfob.

It also makes how the valves operate much simpler than how Audi has them programmed. If you want to have the valves open all the time set to Dynamic. If you want the valves closed up until higher RPM set to Comfort. If you want to snap the valves shut to quiet the car down to not draw attention to yourself double tap the ESP or vice versa if you want everyone to bask in the glory that is your V8 twin turbo sleeper as you roll through town double tap to instantly open the valves to draw the ire of old people yelling SLOW DOWN and GET OFF MY LAWN.

Do you have any install info or pics of the install on a C8 Rs6 ? The instructions I got were in German and also for a different s6 I think I can get it into the car and all I just want to make sure I get it hooked up to the correct wires and had not found a definitive answer I was going to install it when I get my redstar resonator deletes as I will already be under there ..
thanks

If you can shoot me an email with the order info/seller/exact application I should be able to assist. North American resellers should be including English instructions that are specific to the North American market. Email: contact@europrice.us
