Active Exhaust sounds like crap.

Surely just moving the valves from quiet to track with the key on will achieve the same thing ??

I honestly don’t know, but my gut tells me that’s not guaranteed to work otherwise why would Ford have a procedure (that would take up more of the techs time) ?

I just found a way around the Ford procedure, that achieves the same goal, but on my time and not the techs.

They (my Ford tech) were already doing me a favour and I A) didn’t want to cause them more work, and B) didn’t want to have to piss around doing the Ford procedure, in my time, once the car was back home

I wrote this on fitting the actuators on another thread, it may help here

Would it be possible / easy to remove and reinstall the actuators and the springs with the exhaust still on the car ?.
Their is enough work space but you won’t be able to look down on the spring to get it seated ??

As I have done it off the car and have a feel for when the spring is properly seated I think it's probably possible, but doing it for the first time, on your back, with limited access might prove a bit tricky to know if you've got it right.

In all honesty, if it was on the car and it was on my time, I would just follow the Ford procedure (remember that at the time, I had a reason NOT to do the official procedure)

Good point
I’ve tried the ford procedure a few times now but it never seems to do anything.
I never get the clicking noise and assumed it hadn’t worked.

I have found that in normal mode, when the car is cold, the engine is in a different mode and the exhaust has more pops and gurgles between shifts (6MT). Not as much when in track exhaust. I think the reduced backpressure when the engine is cold is why. As for the sound, I have an H-pipe and with the active exhaust is sounds great! Quiet startup is GREATLY appreciated for my 5am workdays, so I love the active exhaust feature.

Also, on those early morning commutes, I have found that driving in sport mode helps get the attention of deer, who want no part of it. I believe that the cars exhaust has saved me from a few accidents...Still need to watch for armadillos and possums though.

I think that’s got more to do with cold engine strategy ?.
running rich when cold and some excess fuel gets in the exhaust causing the pops?.

That's what I think also...I've just noticed that when cold, running in normal mode, I hear more pops vs. running in sport/track mode. However, the rich program makes everything a bit louder.

Yes the engine almost sounds rough when cold and then smooths out

Yes you can recalibrate them. It will take about 20 minutes of your life away from you so you need to make sure you do it exactly correct or it won't work.

Step 1: Get in the car and make sure the doors are closed and unlocked. You cannot open the doors, lock the doors or touch the brake pedal during any part of this procedure or it will not work.

Step 2: Start the engine and then shut the engine off. Again do not open any doors, windows, do not lock anything or touch the brake pedal. Now you will want to turn the accessories on but NOT start the car. So hit the start button without pressing the brake! Let everything power up. Once powered up hit the start button again to turn everything off. You will now wait 10 minutes until the car goes to sleep on its own. You will know it has gone to sleep because the radio will power down.

Step 3: After the car is in sleep mode you will once again press the start button WITHOUT hitting the brake pedal. All we want to do is power the accessories NOT start the car. When you press the start button within 20 seconds you should hear the exhaust actuators click. That is the actuators opening and closing fully to calibrate. If you do not hear them click then you have done the procedure wrong and need to start over. After you hear them click wait another 20 seconds and again hit the Start button to turn everything off.

Step 4: Wait 10 minutes until the car goes to sleep again. Once again you will know it has gone into sleep mode because your radio will turn off.

Step 5: After it has gone into sleep mode a second time you can now start the engine. The programming should be complete and any error messages while trying to change exhaust modes will be gone.

Holy shit my active exhaust is fixed thank u
