Simply having a resonator wont reduce rasp. A resonator will reduce or remove droning. A resonator is designed to delete the specific sound waves that cause drone. The only way to really reduce rasp is to keep the cats in the exhaust system.
If you really don't want to replace the over pipe, Nameless (and just to mention I am not affiliated with them at all they just make some really top quality stuff!) also makes just a down pipe that you can get with a resonator and cat.

Sweet! Again, thank you for that information.
Regarding the overpipe...it's honestly not the amount of effort, it's just a hassle (= money) for probably not what I'm wanting to do here. My goal is to gain something for not a ton of money (isn't that everyone's?? LOL). It just looked good on paper to buy the Invidia pipe for just a touch over $200 and call it a day.
So I guess the question here is...would I really gain any volume at all by just replacing the stock front pipe with the Nameless (or any other catted) front pipe? I realize there's performance to be had here also.
