Question:

What is the difference between MF11219 and MF12219? is one louder? different Tone? Going to be on a 5.3 Silverado with no cats, headers and cam. at present I have the MF12867 I believe and it is too loud.

They are both going to be nearly identical in tone but the difference is the size of the cannister. The part # MF12219 is 5 inches tall by 8 inches wide and 20 inches long whereas the # MF11219 is 4 inches tall by 9 inches wide by 20 inches long. So the internal volume is the same which means the tone and volume will be basically the same. The reason the two are made is to fit different areas on different vehicles.
