Do you have downpipes?

I have catless dp + AA resonated single mid + stock muffler. I don't think the resonator does much with how small they are diameter wise. This setup w/ valves 100% open it drones. Valves closed the drone is reduced by ~90%.

I welded in 4.5" gesi cat right before the brace and it helped my drone and reduce the overall dB by a bit. I still close the valves on highway cruising though and the drone is basically 99% gone.

If you want to keep the AA muffler. I would suggest you either buy resonators from like vibrant or Aero and get them welded on. Or look into a different midpipe like Supersprint.
