Almost kind of a whirring wooshing noise when I apply the brakes hard or easy. I can tell by the noise the pads are just starting to make contact with the rotors. My exhaust is very loud and I can still hear it over the stroker with 3" 2 chamber 40 series Flow Master mufflers. Wife and I went for a 40 mile cruise last Saturday and she asked me what that zzrrr zrrrr zzzrrr noise was and thats how she described it She said she could almost hear the holes in the rotors going past the pads.
