I have an exhaust leak, but that can be fixed, I'm wanting to know what is causing the rasp sound in my exhaust, I just did a search for the same setup, and a kid has it, and it has no rasp... Could it be no resonator or something.... Please watch and let me know.. I have a 2.25" piping setup, with I/H/E full setup on the RSX-S muffler... Here's the video...

if you are running no resonators or a test pipe then that will cause the exhaust to sound raspy
