  1. i have a 2008 mustang gt and at about 70mph, 3000rpm i get a high pitched humming noise which sounds like it is coming from the rear of the car, i was wondering if this was common or if anyone knew what could cause this, thanks
  2. I dont have any issues. 55k miles.
    I do have a rattle in the back somewhere after I put in the pype bombs. thats the only issues I have.
  3. Any mods? Heard if you have a one piece ds you'll get more nvh
