pipe between muffler and resonator looks strange
The pipe between my muffler and resonator seems rusted on my 2016 FRS, but neither the muffler or the resonator seems to be rusting. This is strange considering that all three are connected, and that somehow the pipe in between these two things became selectively rusted.
Is this normal or is this a cause for concern? And if it's an issue, what caused it and what could I do about this?
