wow... looks like that top speed is an ear popper. Not familial with your exhaust but familiar with 3k drone a little. Have a full NHP system from headers to tailpipes (200cells cats) and wrapped everything in asbestos with SS clips every 10cm. Nice and tight. Chopped off drone by 50% I'd like to think. Lot of work, maybe not the best way to cancel some.
Fastest way to cancel drone is to travel with Max and Igor avalera as passengers (see link below). Perfect for low speed 2k~3k rush hour commuting (e.g. 07:45am). Set the volume at #6, low mids and bass at 90%, and I promise you that drone with magically vanish. Starts a great day also!
ps: Has to be the 'genuine' Max and Igor material. Nothing else works on drone.
