i ended up putting in a round magnaflow as a resinator and keeping the corsa in there. pn14619 just incase anyone has the same problem someday...it did the trick. its way more quiet, rasp is almost completely gone(barely hear it when i stomp it), and the sound is actually good now...i think its better than the corsa catback with the factory cats in there.
