2015 mustang gt exhaust pipe size

[yankeefan3]

I'm looking into getting some mufflers for my GT, and I'm trying to figure out if the piping size is 2.5" or 3". Can anybody help me out, can't really find anything on the forums. Thank you

Factory is 2.25, but you should still measure to make sure. I suggest buying a catback. Less chance of getting something botched.

Its 2 1/4" and necks down to 2" in some areas.

MAk 3" off-road pipes with any catback other than sw will be a good choice .

I chopped off the factory resonator and replaced it with a 2.5" X-pipe and got 2 magnaflow mufflers (part #12866) and 2 tips (part #35136) and welded them in place of factory mufflers and tips. It sounds very deep and nice in my opinion.
