Akra slip on & downpipes +n55 midpipies

Does anyone has that set up.? I do have it and sine I installed the n55 mids, there is a raspy metallic noise. Does anyone experience it?

When I blimp the gas at slowspeed and in 2nd or 3rd gear,there is a rasp sound that last like 2seconds

Raspyness usually comes from having a catless down pipe with not enough resonators in the rest of the exhaust. Try upgrading to a different mid pipe that has more resonators instead of the 1 big one on the N55.
