Tonight while cruisin around with some buds we came to a light and we just did a usaual reving of our stangs. I kept pushing around 7500rpms when my boy pulls up next to me with his draw dropped saying the car was throwin flames out the exhaust. Not just a lil he said but alot. I think its ok but im just worried if this is something to be concerned about? I check the plugs the other day and its not like shes running lean or rich. Is it possible its just unburned gasoline falling out the exhaust. I wasnt to happy either because the heat from the flames actually melted the bumper a bit, no much but left a nice black stain on a white car. I wont be doin that again i tell ya.
