This blows. Just put on the Perrin Catback, and guess what, the rasp is STILL there! What the fuck? So now I'm thinking maybe I should just go back to stock front/over/mid pipes and just stick with the RevWorks UEL's and the Nameless Axelback. Which sucks, I really wanted to squeeze out all the performance I can out of this engine.

I don't understand, since I know people have the same setup of Perrin 2.5", RevWorks UEL's, and the Nameless Front/Over with no rasp. Could the Helmholtz somehow be causing rasp? Seems counter-intuitive.
