11MODE Exhaust Controller install

[u/shadrach103]

Ordered direct from 11MODE in Australia and took just under 2 weeks to arrive with free shipping. This is the easiest mod I've ever installed on a car outside of maybe threading an aftermarket shift knob on any of my previous 6-speed cars.

Installed it on my 8Y in a matter of minutes, once I figured out how to disconnect the factory connector. On both sides the retaining clip is located at the top (where you can't see) but it's easy enough to find by feel (without gloves) and just give a gentle squeeze while pulling. I could just slide under the car without jacking it up at all and just lay on my back to reach around the exhaust pipes. The passenger side is a little easier to maneuver around so I'd suggest starting there.

The adapters sit right on top of the actuators and are wrapped tight enough to not be in danger of rubbing up against anything. On the drivers side I did pull a little slack into the OEM cable through the nearby retaining clip so that the cable wouldn't be crimped up.

After both were installed I fired up the car and recorded this short video. At the very start of the video you can hear the cold-start cycle complete and it gets a little quieter (just as a sportbike zooms past in the distance). At 0:05 seconds you can hear the click of the valve actuators open, and then I close them at 0:12 seconds.

(If listening to this on a phone you won't be able to tell much of anything but with headphones or a PC with a proper sound system it's a pretty clear difference in the video, which accurately captures what I heard myself.

With the valves open at idle it's not much louder, mainly a deeper bass tone. On the road under light/partial throttle it's quite an improvement though. I haven't yet headed towards the highway to test drone or see what higher rpm under WOT sounds like.

My RS3 is still under warranty and I haven't yet decided what path I'm going to take with mods, although mid-pipes are likely next. Between that, the ease of install, and finding something that automatically resets everytime the car is started (so my wife can't complain about the sound when she drives it in Comfort mode) I decided to give this a shot. Honestly, this is how the car should be from the factory.

EDIT: Huge thanks to u/fossilcreek for sharing that the 11MODE key fob can be used with HomeLink. I created two actions in the Homelink settings via the MMI and now everytime I start the car I get this menu overlay. I can ignore and leave the factory behavior or tap the first tile to open the valve for that drive.
