I came back from work today. When I got home I realized there is white dust inside my exhaust tips. The car felt fine. Checked for codes and nothing showed up. Any ideas or tips would be appreciated!Attachment 197708

If you have an open flash. Or ecutek to see data logs. Look to see if your not running lean. It could be that.

Checked the AFR and it seems to be in a good range when under load.

I was going to ask you what that white dust tastes like thinking it's road salt, but I see that you're in Mexico.

I'll guess maybe coolant residue from a possible blown head gasket?

OHH noo. I thought about it. Did the basic checks, no brown oil, no coolant discolor, no white smoke, no overheating. I guess ill take it to the mechanic shop this week for further inspection.

I had the cat in my stock header fail at one point and it covered the entire rear bumper of the car with dust that looked just like that.

Well since he’s in Mexico maybe he ran over a brick of cocaine? /S

OP it’s probably your cat as mentioned above.

Could be running lean. Has the car been modified or tuned?

Hello,
I was curious if you ever figured out what was causing the white dust. I had exactly the same thing happen to my car this past weekend. Also nothing weird with the oil or coolant. I’m suspecting a damaged cat. Eager to hear what you learned.
Thanks,
Mark

I think what'll happen is his car won't smog and he's going to be SOL.
