Dahler exhaust valve controller installed (G87 M2)
 

As the title says installed the valve controller two nights ago. IMO this is a must have mod. Personally, I don't like the fake engine sound track that comes with having M sound enabled but I do like the louder exhaust note. The Dahler controller allows you to disable the M sound and have the valves open all the time. I'm noticing an increase in throttle response at low RPMs too but maybe I'm just imagining this.:confused2 Overall impressed and probably the easiest install I've ever done on any car.

Congrats:thumbsup:

Opening the valve will not provide any noticeable power improvement

Perceived power improvement maybe :D

Sounds can do that.

Would love to learn more about this . I was just wondering how to keep the cable open all the time . On my m40 I replaced the rear mufflers and just left the entire valve assembly there but not attached to anything lol.

In my m340 before I installed the Mpe, I just unplugged the wire and zip tied it.

Now I’m wondering how I make this m2 keep the valve open all the time. Would love it to be open on start up too and without having to go into a sport mode etc.

Thanks

Just install the dahler valve controller. Plug and play. And leave it in the open position via the remote.

If you get a valve controller, you can force the valves open at 100%

And if, for whatever reason, you need to close the valves, you can do so with a click of a button.

Thanks guys. Just found an install video .. certainly not difficult and nice to be able to close them at will. I assume if opened they will stay open even if car is turned off the back on? Is this unit expensive ? I just spent a ton on brake pads lol and need to take it easy otherwise simple fuse pull and call it a day lol

Just found it , $500 lol I think ill just pull the fuse for free and take 80% open …

the SST and MAD valve controllers are $285

Nice that’s much better. Are they the same easy install etc?

SST/MAD/Dahler all are installed the same exact way, its a very easy and straight forward process

Thx I’ll be ordering something soon. Based on what I see and read there is no harm correct? Ie dealer won’t care if they see this or anything silly like warranty issues with anything ?

I really don't hear the difference from the valves being 70-80% open to fully open. I wish I could hear a car in person. From the videos I can't discern the difference from 70%-100%.

Correct

hundreds of people have this upgrade and can hear the difference, its 100% there

We have a more competitive option with more features.

Did you guys release it yet?

Shipping this week :) Maybe as early as tomorrow!

@[Info@mad-us.com](contact:577984) Just went and looked at your link and you're right, that is a much better option of what's out there.

Since we are so close to Black Friday, will your online store have this on sale in the next couple of weeks?

Thanks!

:thumbsup:

Stay tuned for the black friday sale.

If you are impatient we always have a 5% off forum discount code "MAD".

I like the SST solution. They give you 4 options, on off and a couple percentages open which I think you can set. Plus it remembers whatever you last had it set too.

I also have a OG CG precision first gen that did act up on me years ago, but its working flawlessly every since then, 3yrs later.

lots of good options on the market today with reasonable prices.

Im glad to hear the CG is still working for you :cool!:
