If I'm not mistaken from what I know and have read over the years about the popping and crackling on any of theses cars, you can't "adjust" it you can only tune it out, or leave it there. It is what's called DFCO..." Deceleration Fuel Cutoff". When you let off the throttle the ECM shuts off the fuel to the injectors and hence air is introduced and no fuel, so it pops and crackles. With an aftermarket exhaust it is really loud.
