Hello,

car newbie here,

my 2018 macan S has four exhaust pipes but 1 of them looks as though it’s not going as it’s dusty while the others are clean.

car is running all sweet no issues that stand out. Wondering if it’s just cause I’m not reaching high enough speeds for the car to need to use it or I should get it checked out

Is it the far right that is clean, and there is a valve on it when you look into the pipe? That one only opens above 3k rpm in comfort and 1k rpm in sport mode. It's a sort of bypass valve and will look cleaner than the rest.

If your looking at the back it’s the inner of the two on the left hand side.

I live in NZ so we are right hand drive if that makes a difference
