Muffler Discoloration - Is this Normal?
Hi Guys,
I tend to inspect the car, especially the tyers, every now and then and I noticed inconsistent discoloration of the right muffler when compared with the left muffler. The left muffler is basically intact and as new whereas the right muffler is clearly turning brown/golden color (image attached). Now I understand this discoloration is due to heat, but, why the inconsistency between the right and the left hand side? The dealer inspected the car and as usual their response was: This is normal and nothing to worry about Has anyone noticed such discoloration? any thoughts? Car: 650i 2014 coupe |

Yes, they do that.
Different metal parts change color at different rates due to various reasons. Here is a picture of aremoved 550i exhaust I found on the net showing the typical color changes that happen over time
