I am not. If I don't keep this system with the new hangers I will be going with a 70mm system. Thanks

Interesting. I have no drone anywhere but from 2700-3300 its absolutely drone/resonance.. I'm hoping the hangers fix that.

Are you using stock exhaust hangers? Also what is the rest of your setup. I am running 3" turbo back with a resonated JDL front/over pipe.

I have torque solution hangers, PRL turbo Equal length headers, 3 inch downpipe, VTA dump tube (so it gets loud past 4000 RPM) Ultimate Racing resonated 2.75 inch overpipe and front pipe combo mated to the resonated perrin 3 inch exhaust.

But no problems at highway cruising speeds where i am in the RPM range you are hearing drone/resonance
