    Just finished up swapping a 18+ Rear Bumper on my 2017 Gt so I figured I would gather up all the information needed incase someone else would like to do so. Originally I had just cut my stock diffuser to fit my Roush active exhaust but I was never fond of how it looked nor did I like the look of any of the aftermarket quad tip valances.

    This swap is compatible with any 15-17 Mustang. Keep in mind you will be required to run a quad tip exhaust with this diffuser.

    Note there is one modification that needs to be made to the 18+ rear bumper. Ford changed the style of mounting tab by the outer side of the taillights. On the 18+ rear bumper grind down the ridges on the tab and cut a slit to match the tab on the 15-17 rear bumper.

    Known Exhausts that will fit with no modification needed are the following:
    15-17 Roush active exhaust
    Any 15-17 Corsa exhaust with Corsa quad tips
    Any 18+ Mustang gt exhaust

    From the 15-17 Rear Bumper you will be able to reuse the following:

    License Plate Lights
    Trunk Release Button
    Reverse Sensors
    Wiring Harness
    Side Marker Lights

    About $1200 with paint. Keep in mind I did all the test fitting and install and only brought the bumper cover to the body shop.

    I was wondering about this myself. Glad someone tackled it (and documented it). Need some 18+ tails to go with it!

    Agreed. Thinking about the 18+ euro taillights with a very light tint.

    They're sold that way from the aftermarket VLAND brand if you don't want to mess with tint strips. I have the untinted ones myself.
