I have a 2003 4x4 hand shaker. My question is i recently removed the cat and exhaust. But I have notice that there is a whistle to it but then just a rumble to it. My question is everytime I hear other 6.0 all I hear is the whistle. Question is. Is my turbo bad or do I have to do a full turbo back to get the pure whistle sound.
