Strange comments here.
TNZ4MC swears by them that they cut 95% of the drone.

What is the real deal on them. Do they work for eliminating drone or not?
Very confused.
I love the sound of my Diablo's but the drone when in low rpm 2-3K is distracting.
All aftermarket exhausts have some drone from what I have read so there must be a fix or some mods to reduce it that works.
