anyone here running 4 resonators?

Basically had a muffler delete fine few months ago...added resonators near the trail puppies because I wanted to leave in my secondaries. Drone wasn't too bad..radio was eliminated mostly by the resonators, cut my secondary cats out and bite rasp has came back a bit (but fringe is all but eliminated). I will say I feel a noticeable difference with spool up and power with secondaries gone. My buddy who does not have near the power I do didn't notice much with same setup...guess higher power levels really benefit from this.

On to the question, do you think rasp would be reduced with additional 2 resonators where my secondaries used to be? Anyone else running 4 resonators?

I want add little back pressure as possible and the sound is not great. Only exhaust I honestly like is a akrapovic.
