Welcome to the forum!
Sorry, I have no ides what that exhaust is, but it's certainly not the factory Buell race exhaust. I would recommend looking around youtube for clips of the type of exhaust note you are looking for and go from there. I'll caution you against the Jardine for the Buells. They have been known to rattle apart pretty quickly on some bikes.
Some of the better exhausts are Hawk, Dean Adams (Keda), Drummer, and I have an interesting stainless Supertrapp (old skool) that I like a lot on my STT. The XB's can sound ridiculously good with the right muffler.
I would suggest getting a manual from Buellmods.com to get used to the maintenance for this bike (it's minimal) and check out Buelltooth.com for lots of info on diagnosing or tuning the bike to match the pipe among other things.
