I was curious if this would work, and it sounds like it really does. That's fantastic! Now all we need is someone with some tech skills to make a version that uses GPS to close the valves approaching the track microphone and open them again when you've passed it.Oh do I have good news for everyone!!
For anyone who has driven at Laguna Seca or low sound tracks, there have really been only 3 options. Buy the grimspeed resistors, put plumbing plugs into the exhaust or lift at the sound towers.
I tried making a new separate harness for the valves but they didn’t do anything because I learned that these valves get feedback from the ecu. You can put all the power you want to it but it won’t do anything.
After I was in the process of trying to retrofit aftermarket valves which would have worked but was labor intensive.
Next was trying to program a module to operate these valves seperatley from the car, I just did not have the know how or the time to learn.
Lastly was trying to use the Roush controller on this car but the kit is around 1500 which is looney.
I then researched the oem valves in greater detail and found that Kuster would not give me any information on the valves. I found that these valves are used on Audi’s, some VWs, the Hellcats, and even the focus RS.
AWE tuning happens to make a valve controller that works on these cars except the hellcats apparently.
Well I installed it today and it works exactly as I hoped. You can turn the valves on and off at anytime. Doesn’t matter if you are in full throttle or not as it works independently.
This kit installs as a plug and play, No drilling or irreversible modification needed.
It comes with two rd remotes that have quite some distance, easily 20foot range.
The module can be installed on the driver or passenger valve.
Step 1 Unplug harnesses
Step 2 install resistor on either driver or passenger side harness and zip tie it out of the way.
Step 3 install module onto whichever side of the harness that doesn’t have the resistor.
Step 4 plug the two male ends from the module into each of the valves
Step 5 zip tie everything out of the way.
Step 6 put the car in accessory mode and cycle the valves, you may get an error code on the dash that mode selection is not available. Turn it off and now start the car and you are good to go.
Overall I’m really pleased with the kit and glad I found it.
Here’s the kit, you can find it from numerous vendors.

For around 200 bucks it’s a bargain
From what I understand you have to be grossly avoiding the sound booth and noticeably coasting up 5-6 for them to send out a spot check. If you are running an LS motor w/o cats and straight piped and they see you coast from under the bride approaching 5 clear to the next bridge before 6 your probably guilty ;) I live 3 miles from the track and never worried about it in my Miata race car. The GT350 though....well.....it hurts peoples feelings
Lol. I would be skeptical of an article published on April 1st.
