What exhaust is this? - YZ426F

This came with my bike, I'm not sure what type of exhaust it is...I'm currently running the powerbomb 4, but I'm curious as to what this is.





Looks like an old Thunder Alley exhaust to me... Those haven't been made in a few years.

That specific exhaust hasnt been made in a few years, or the exhausts in general havent been made in a few years?

I wonder if I should use it instead of my FMF..

I believe Thunder Alley went out of business a couple years ago. I could be wrong, but I haven't seen any in about 7-8 years. I can't tell you anything about the performance, but I do remember that they were always pretty loud.
