Hey guys, have a question that I think one of y’all can answer. A couple weeks ago the dealer replaced both Cats and mid pipes due to broken cat welds and broken flex joints, so far no issues with any rattling noises or exhaust fumes. So, my question is…. Why has the passenger side Midpipe color darkened from shiny like the driver side to the color seen in the photos? I know this is heat related and makes me wonder why the passenger side gets hotter than the driver’s side. I’m not worried about it, just curious. I have it scheduled next week to have the emission control module reprogram done under the recall.
