Black Exhaust on Tail Pipes
Took delivery of my 2017 ZL1 two weeks ago. Currently has less that 400 miles. However, I am getting a lot of black soot in and around the tailpipes. Is this normal? The back of the car gets really dirty with the fallout. This could become a maintenance nightmare.

It's normal. My outer tail pipes also show a lot of black soot. The factory tune runs these engines on the rich side.

Better to run lean and deal with the black soot then blow your motor....

I cut the tips off and run the exhuast into the cabin so I won't see the carbon buildup....

Mine were bad but you just gotta clean them....
I just used a new soft bug scrubber until my Adam's polishes order comes in.
