I recently installed the corsa xtremes on my 14 and its probably one of the best sounding exhausts I've heard, but I also have AR long tubes and off-road hpipe. Go with the xtremes, you wont regret it
I had ford replace it for free because it's not how the car was suppose to come. Just get a vin with cobra logo and order a new cluster using said vin #
I have an early 2014 that came with the pony logo, and it drove me nuts that it didn't have the cobra. So I switched it, and it's much better. All you have to do is find a vin # for a 2014 with the cobra logo and have ford order a new gauge cluster using that vin and that's it.
