Did you add the resonators to eliminate raspiness, quiet system down overall or both? What resonators did you add and where did you add them in line?
Honestly you'd have to ask D3 what resonators they use. They were in-line after the cats. Very slim. I added them because without them, I was telegraphing EVERY throttle input to the cars around me quiet aggressively. Even light throttle. Adding the resonators toned down the light throttle inputs without really diminishing the wail when I meant it. They tell me it will reduce the rasp as well, but I never noticed much of a rasp either way in general.
