Ok, i've had a few opinions as to what is flying out of my exhaust in handfuls, but i just want 100% confirmation. I have the Stillen SC, HFC, and CBE. The below is a pic of a couple of pieces of the metallic like chunks that are spewing from my exhaust pipes. I've been told it is coming from my HFC...is this true? If so, if after replacing my HFC, will the pieces that are still sitting in my muffler damage it in any way?
