My Stillen CAT back Drone somes times bothers me around 2000 rpm,

Just found a pairs of theses & pluged it in. It reduced the noise noticbly.

I am pretty happy with my solution.

All your doing is slowing the exhaust down and forcing the pulse the cancel itself out - basically detuning the exhaust you paid for.

Likely killing about 1/2 the horsepower gain as well.

The issue with drone are poorly designed mufflers. The systems then rely on additional resonators to tune sound - those usually add more drone and tune the drone further so it's more bearable.

A really good exhaust system should really only need mufflers and a small resonator for dynamic sound resonance tuning. Like the stock systems. The mufflers should do the real work, the resonator should put the wow in the systems not compensate for the muffler's inability to produce.

As far as I know - there's only 1 system out there right now that does this right...
