I worried about that to but when I changed to free-flow exhaust with resonated exhaust tips, the stock resonater came off. I than changed to Sho-Shops Y-Pipe, thinking again about this problem. But never had a bad rasp sound. I would take it off, but I have a SVT and don't know if there is a difference.
