That's the thing, I don't know.As long as they are the same size tubes, they will be able to be attached. I assume you are getting 2.5" pipping; make sure the X pipe and cat backs are both the same diameter.
In the V6 world, most people get H pipes with dual exhaust because they like the sound better. An H pipe will give you a deeper toner, where as the X will give you a raspier sound, but you will gain a couple extra Hp from the X as well.
Are you doing this work youself, or are you having a shop weld it all together?
What exhaust setup are you getting?
Wrong. Everything under the sheetmetal is exactly the same as the 05-09 Mustangs. As far as piping size, the stock mid pipe was 2.25 and the pypes dual kit made it all 2.5 from the cats back.As far as i know that would work for most setups as long as its not a kit for the 2010s i was told that that lengths of the cars changed on them and so kits wont fit anything but that car and on the new ones the pipe size is different. just make sure you look at all the specs before you buy.
What's his face a few up with a 2010 mentioned the different sized pipes.i tried to get the 2010 exhaust set up made by ford and they ordered it then called and said it wont work on my V6 because the length from the cats back would be short ???? maybe its all bs i am not sure the said that system wouldn't work tho
