Default Brown-ish liquid drops behind '12 STI

Hi, i just noticed after parking, behind the car, there is a stray of droplets follwing the car. I don't really think it's engine oil since i compared both colors and my oil would be slightly darker. There is no oil accumulation or whatever under the car, only a couple brownish droplets followin the car that I noticed just after parking. I checked the oil, it's fine. 2 of my tailpipes are however pretty dark, like carbon black. The car has 26000 kilometers and an oil change has been performed by the dealership a week ago. What could it be?? Thank you

No not rusted... It's just carbon build up inside of the exhaust, and when you turn on your car all the condensation (moisture) gets mixed with the carbon that's inside your exhaust and drips out black residue
