Anyone installed fords "active exhaust upgrade"

[MAGS1]

Is the rear valance swap required to fit the Mach 1 mufflers into the GT?

As far as I know, yes. The tips are bigger and I believe the hangers are slightly different.

edit: here’s the instructions so you can see the breakdown. Looks like there’s some intermediate hangers required that come with the kit

Did you install it?

Yes I did. Sounds actually a tad quieter driving around but definitely more refined and "lumpier".

It's also possibly it may come across quieter because of the new valence, or whatever the technical term is for the under body tray thing

I believe the Mach 1 tips drop a little lower than the stock GT tips, so using the stock GT valance with the Mach 1 mufflers may look slightly strange with the tips lower from where they should be.

Yes, the drop is significantly different :

I noticed with the Mach 1 valance you no longer see the bolts for the differential where you would see them looking at the car from the back with the stock GT valance
