Has anyone else ever notice a black smoke like film on the tip of your exhaust on a racing beat exhaust? about every week after i clean it off, its right back on there. what is causeing this? i think that its probably from getting on it too often. also, for the first 6 months, when my mom was driving it, she always filled up the tank with regular gas and i now fill it up with premium.
anyone know the problem? if theres one.
