Ive always thought that Stillen exhausts were known to be more raspy than most. I can remember a friend having a Stillen exhaust on his 99 Maxima a long time ago, and it was raspy in higher RPM.
When you add test pipes, and increase exhaust velocity and flow, you're going to amplify or increase the likelihood you're going to hear rasp. Makes sense.
