Exaust leak

[Nathanspindle]

Hey guys starting to notice my ficm becoming cover in soot would that be a cracked up pipe?

That would be my first guess. Cracked up-pipe or bellow. Best way is to snap the throttle and have a buddy look in there with a flash light and see if smoke comes out. Could also be a turbo exhaust flange gasket. My bet would be up-pipe/bellow imo.
