Default Drone

Found this on another forum:

Re: Exhaust drone...resonator help

Another way to fix the noise would be to change the point of resonance . You can do this by adding weight to the exhaust. Everything has a point of resonance, this is probably the easiest way to change it and increase it to the point to where you wont hear it. Adding resonators would help also, but this is why on some of the late model vehicles, they have weights clamped to the exhaust pipe.

The drone has been around forever. I'm going to check the hangers. Forgot he added some.
