I have a similar setup...except I have Ar Catless downpipes, Vibrant resonators in place of secondary cats, and 3" alluminum piping from the resonators.
Sounds AMAZING! and no rasp and barely any drone. I don't have drone when cruising in 6th gear or anything. I only get very slight drone when doing an initial acceleration but only lasts like half a second lol. Its wicked! Mine is loud though, loud enough to turn every head on a street when i romp on it but its not loud if i drive like a grandmother lol.
Oh and above 4500rpm it sounds like a race car
