The exhaust pipe has some black carbon inside of it on a 2014 kia forte is this something to be concerned about?
No, they all will get that sooner or later, if your concerned you can run some SeaFoam through it, just pour it in the fuel next time you fill it up, it may or may not release the carbon but it will help clean the injectors. The only thing to watch for is if it blows some black smoke at start up, if it does them you could have some leaking injectors, but if they aren't too bad the SeaFoam will help.
Anytime. Come on back with any questions you may have.
