Normal exhaust colour?

[WerriesM5]

All of my cars run Sasol 95 unleaded, I never put additives in.
She goes like stink and drinks petrol when you hammer it..
Well after driving my 540i/6 very fast for +/- 80Km this is what my exhaust looked like.... :dropjaw:

Looks like the good 'ol leaded petrol pipes...white!

 

[Scouse]

Yup, what Hellas said, looks very nice like that :clap:

[Spy007]

Mine is the other side of that white, Ie Black

 

[rick540]

The white/grey is lead deposits

Very confusing as you say you use unleaded.....

 

[veridico]

The exhaust looks way better with the white, but it is slightly confusing as to why it would be white.

 

[Skwinty]

Yes it is confusing. Would de-catting the exhaust perhaps cause this after a good stomp. :thinking:

I also can't understand why it's that colour... I do like it!!!
Some people told me that it is running lean and burning like that... :thinking: Whel I got +/- 5Km per liter on that trip so I don't think it's running lean...
