Okay so im running Tomei UEL catless, Tomei overpipe, Invidia Catless non resonated FP, and the 3" Greddy RS. There is a ton of rasp middle and top end, and want to have the deep rumble for most of the rpm range. I understand that sometimes you cant get rid of the rasp completely but will a Resonated front pipe or dual resonated front pipe get rid of most of the rasp? Opinions on which one please.
