What exhaust is this?

[Boosted DSM 32]

Does anyone know what kind of exhaust this is? To me it sounds amazing and would love to get one that sounds like! Im sure some of the sound has to do with cams, internals, dump tube ect but if anyone could help me out that would be sweet!

I DO NOT CONDONE DOING ANYTHING ON THE STREET this video is strictly for the exhaust sound!

Sounds like a 3in with no converter to me.

I have a 3 inch straight pipe with no res on converter and it sounds nothing like that and my buddies talon has a 3 in straight to a magnaflow and it doesn't sound anything like that either that just sounds a little different to me I love it haha I do have the stock down pipe tho, maybe if I got a 3 in down pipe and an external dump it would sound more like it
