So I have a muffler + resonator delete on my '06 IS350. Sound is great but the drone is crazy. I want to keep the loudness (as much as possible) but get ririd of drone.

I was wondering how would I go about that?

I had 2 options:

1) Add a dynomax mini muffler where the resonator was (I just dont know if that get rid of drone)
2) Do the same thing but with a invidia mid pipes (again I dont know how much drone that will get rid of)
3) Last option, just add the stock exhaust back on and get electrictronic cutouts

Any suggestions/recommendations? Thanks so much!

You are pretty much always going to have drone when you remove exhaust components. Try getting some flow through mufflers, that should help quite a bit to reduce light throttle volume.
