Does a Z-tube with Pop-charger make for a deeper sound or just louder? Kinda lookin for more of a growl out of the car without changing stock exhaust.

 

i dont think it changes the exhaust sound much at all...

 

I have a Ztube and a drop in K&N filter and the difference in sound is just a slightly deeper growl, and you can actually hear the air swooshing in a little more now. It sounds good IMO, just a little more aggressive than before, but not ricey. I haven’t really noticed any change in the exhaust note. The power gains are minimal, barely noticeable.
