I am tired of the hairdryer/jet airplane sound out of the exhaust on the 6.4. Would removing the muffler help or make it worse? Are there any mufflers made specially for getting rid of the sound? Are there any tuning options to do so?

I just started playing with the Mcc software. Trying to get the values right to keep the vanes open at idle is harder than I thought. Mainly uploading the new tune file everytime I make a change takes forever. Getting closer. I wish there was some good instructions on "tuning for dummies" that I could get ahold of!
