Looks like it's all stock, nice looking car! Post some more pics of the car as a whole if possible. Also, take a pic looking down at the turbo (or just look) to see if there's a bit metal football thing down there, that's the trap.

BTW, you don't need to change all that stuff to make it run better, just get a pipe made that bypasses the trap and call it good. There's a link in the DIY section that shows what you'd need to do it.
