well, drone is litereally resonance. you can do a bit of estimating by using the length of the pipe vs rpm and number of exhaust pulses etc...
one way to minimise drone is to break up long lengths of pipe into uneven, shorter lengths. this means the drone will occur at higher rpm, where you will notice less..
i did this with my exhaust, using 2 resonators.. pipe is 2" which is a little big for a 4K, but drone/resonance starts above 5500rpm, which is where the extractors are designed to resonate...
a few thoughts..
