It's your tires. Yes, the tires. Tires will make a roar/growl/whine when they are worn or cupping and the sound is noticabely louder when in corners. Check the tire pressures(which you should be doing at least weekly) keep them at 38 or 40 psi. If they are cupping badly the tire pressure won't help new tires is the fix.
