The difference in sound volume between stock and a high flow cat is bigger than the difference between a high flow cat and no cat. Any cat will help with rasp too.
Do you already have a cat-back installed? I put on my front pipe (2.5" Perrin catted) with the stock exhaust first and it was definitely noticeable if you really listened, but no one else would know. The cat back made way more difference in noise (2.5" Perrin resonated).
