    Smoke from exhaust

    black smoke = normal. This is why your exhaust tip is black & not chrome & also why your bumper, well mine at least since my car is white, is always stained.. & I whipe it daily.. Its just unburned fuel. Remove your cat & it gets worse =} turbo seals will give you a more white w / blue tint smoke..
