I am looking to buy a X pipe for my 2012 Mustang GT, I have a corsa sport axleback currently on it now with a JLT intake. My questions is if I can a X pipe will it make it a little deeper and louder or smoother and quieter. I had seen people say it makes it louder but I contacted corsa on their X pipe and they said it actually makes it quieter and smoother. Which X pipe should I get?
Will an X Pipe make it louder or smoother and quieter?

Catted or off road?

In my experience, a catless x-pipe is loud and raspy. My aftermarket catted H was nice and deep with a clean sound.
After cat x pipe.
That's pretty much it.

That doesn't make any sense. The cats are on the X pipe. So if you get an offroad X then its catless. If it has the cats then its catted....
Well the borla x pipe doesnt come with cats now does it? And its not an off road

Aftermarket cats are high flow which is why they are louder they also fail emissions sometimes. The H over X is your preferance of sound.
Offroad X is just what everyone calls a catless xpipe..
That x pipe re-uses stock cats..
Go on youtube and see what you like the best.. IMO catless is the way to go with a nice catback, but its all preference and if you need to pass a visual inspection or an emissions sniffer then take that into account.

Yeah that is a weld in where you cut off your H and weld in the X. You need to just get a catted X pipe. That is like worthless to do because you are still going through the cheap restrictive oem cats.
The cats are separate on these cars, so you can bolt in an X/H behind it.
Off road X/H pipes include a section to replace the cats.
Borla and FRPP both have emissions legal X pipes that don't require cutting or welding.
This has pictures if you need them to visualize.

Don't forget that some cars stink real bad without the cats mine did thats why I put them back on.
From what I've heard the stock cats flow pretty well. That said I personally like h pipes and I'm eventually gonna do a high flow cat h
Pretty much what Stampede said... Clearly there is alot of confusion in this thread. The cats are attached directly to the shorty headers. If you replace the headers with long tubes, THEN you need to determine a midpipe that have or don't have cats.
The Borla xpipe that bolts in aftcat doesn't get raspy at all and is definitely louder than the h-pipe. Now, if you replace the over axle pipes as well, then it definitely get's louder than the H.
I went with the Borla S-type kit with xpipe and will never look back.

Xpipe's smooth exhaust pulses. Hpipes do not. More turbulent flow at the junction points, not enough to increase back pressure, but enough to affect sound. Think of smooth flowing water vs turbulent water.
I purchased the borla s-type catback for my 5.0 and ran it with the stock h-pipe for a little while then switched to their x-pipe (had a problem getting it to match up to my pipes without loosening the bolts at the cats).
From experience with the 5.0 exhaust:
h-pipe = louder, deep, a lot more popping, and rougher sounding exhaust
x-pipe = a little quieter, a little higher pitched (still deep), less popping, a lot smoother and a better tuned sound
I agree that the x-pipe used to make the older mustang raspy (I had one on my 2001 Bullitt with flowmasters) and the h-pipe sounded nice, deep, and gave an awesome rumble vs the raspiness of the x-pipe.
But the exhaust on the 5.0 sounds so much smoother with the x-pipe vs the h-pipe (I'm comparing to the stock h-pipe, not sure if aftermarket h-pipes would be any different)
I went back to my h-pipe a couple of weeks ago to try to remember what the h-pipe sounded like and see if I lost any low down torque and switched back to my x-pipe within a couple of days. I actually felt like I lost torque with the h-pipe, like there was hesitation and the car did not run as smooth either.

Sure. Why do you ask? I don't see a helpful piece of info/persective from you. Hpipes help equalize as well, vs unconnected straight pipes, but the X is smoother. I'm not a fluid dynamics expert, but it sort of makes sense to me.
Could you provide some info?
I have the Corsa Xtreme w/ the Corsa X pipe. This X pipe fits behind the cats. According to Corsa this setup will give you 10 hp..... whatever.... I like the sound ; people have complimented me about the sound. These cats flow good enough; you'd be better off spending your coins on something else.
