I recently bought a 97 Cobra with 103K miles on it...Looks good, runs good, sounds good with Flowmasters and X-pipe. But after about 35 or 40mph, it makes a loud humming noise while accelerating. If i lift the throttle, it silences it. Thats bugging me out. Anyone had any similar problems? I first thought wheel or Driveshaft problem, but changed rims and tires, and the shaft is stock, and shouldnt go away when i lift....HELP !!!!
