i bought my car about 18 months ago, ive had my license for about 9 months. my mom has been complaining that i accelerate too fast out of the driveway and my car is loud when i accelerate. i couldnt figure out what the sound was coming from, i dont drive like a maniac or anything. i popped the hood the other day, and i have headers. did headers come stock on '98 V6 mustangs? buying a used car, you can usually tell what kind of person owned it before you. my car had no mods, cheap tires, a few cigarette burns in the carpet, some body work had to be done. i dont see why this careless owner that had my car before me would put headers on and keep the single exhaust.
