Hey guys might sound dumb but for whatever reason my car smells like exhaust fumes pretty bad. You smell it faintly while riding in the car, but when you get out u really smell it on your clothes. Im not sure whether its coming from my exhaust which is dumped right at the rear tires or from the engine bay. The scent is most noticable when traveling at highway speeds, so i think its coming from the engine bay and threw my cowl hood. At first i thought it was coming from my exhaust going into the trunk somehow, but i taped up some holes that the previous owner had drilled (for the rear mount battery) in the rear and that didnt really help any. Any ideas? Car is carburated BTW...
