    I have some GT 350 mufflers that I am putting on my GT - I figured out the active exhaust wiring if anyone wants to see.



    I should have some videos of it on the car soon!

    I’m interested to hear if there’s a difference, but I’d imagine you’d lose 2 of the 4 modes by doing this as the 18+ has 4 available exhaust modes whereas the GT350, to my knowledge, only has 2.
    Something tells me that this is going to be a bit fruitless in terms of a difference in exhaust sound, as the GT350 sounds as glorious as it does due to it being a flat-plane crank engine, not the mufflers. I wouldn’t mind being wrong, though :p

    We shall see! I really want to be able to open the exhaust at any time really. I dont think it will be fruitless even if it doesn't make a ton of difference in sound with the second pipe closed as I really like the look and I'll be in it for about 600 installed (mufflers, valance, install)

    Ah, I missed that. Now this makes sense. I’m guessing you can change exhaust modes through the info screen between the gauges via s forscan modification?

    I installed GT350 mufflers with an X pipe on my old '15 GT. Wired the exhaust valve controllers up to a DPDT rocker switch. Sounded glorious. This was about 3 years ago. Loved that exhaust setup.

    I have a 300A car (no toggles) with active exhaust and exhaust modes are in the settings menu between the gauges,

    OP has a ‘17 GT, which did not have active exhaust as an option. He’ll need to figure out some type of modification to control the baffles. I assume he could unlock controls via forscan if Ford Engineers put the coding for the GT350’s AE in all Mustang models (much like the digital speedometer for the information screen that GT350s always had but was absent for 15-17 GT, V6, and EcoBoost models).

    So I've got the wires all figured out. Putting it on a switch that controls the open/closed functio . I won't be able to do any in-between settings though. It's all on now and sounds pretty good open. I think closed it will sound stock (I have the resonator in still). More to come!

    Did you get an aftermarket switch (like what the Roush system uses) or did you re-program one of the stock toggles?

    How do the modes work if your software doesn’t reflect it on the dash. And
