Any Cure for Raspy Exhaust?

Any Cure for Raspy Exhaust?
I got the Invidia g200. Just put on some Labree resonated test pipes. It's raspy as expected around 3K rpm. After that, i think it's just loud enough to not hear the rasp. Any cure for this? I was thinking about getting an extra resonator welded onto each pipe to muffler the sound and reduce or eliminate the rasp. I did this on my old accord with the Greddy Evo, I had bought used from a wreck. When I got a custom straight mid-pipe on it, it was raspy but once I threw a resonator in the middle, it was perfect. Any comment on this? I doubt the resonator would impeed too much flow but it's a concern. I'd like to hear some feedback since I'm sure many have TP's on this board.

I had rasp/buzz at 3200rpm with Stillen dual exhaust after I installed TP, for about a month I didn't rev pass 3000rpm cuz I couldn't stand the rasp. I started to not want to drive my car. I finally got Fast Intentions Intimidator exhaust last week and sounds so damn sweet now, no rasp at all.

most test pipes, even with resonators, are notorious for raspiness
though i have heard the best test pipes for minimal to no rasp are the fast intentions ones

Thanks for the reply but you merely confirmed what i already stated w/o adding any additional fact or recomendation. not trying to be a smarta$$ but i clearly stated that the rasp was expected and was seeking comment regarding adding additional resontator to my g200.

The key to no rasp with Resonated testpipes is/are quality mufflers with the system - hence a higher quality exhaust system designed to be used with testpipes if so desired.
There isn't much you can do other than continue to add other pieces to the system and choke it enough to work - but after you spend that money, it'll be too quiet or not perform the way you want it to or the way it did.
Is the the first exhaust you have put on your car? Many people put on 3-4 exhausts before they find the right one or just give up and settle back to stock, or the last choice they made.
Best bet is to listen to others that don't rasp and sound the way you want your to...then duplicate it.
I can of course recommend a favorite of mine

Khoa,
Believe it or not, I have a bit of rasp with my F.I. resonated TPs!
I'm looking for a cure as well. I have the Greddy EVO2, which already has a resonated X-pipe (at least I believe it's resonated), so I'm not sure if the Magnaflow solution will do anything for me in this case.
Any thoughts?

Just got back from exhaust shop, no room to fit the 20" resonator they stock. Either find smaller ones, which are are hard to come by or do the Magnaflow x-muffler. I think that x-muffler would directly replace my current X-pipe nicely and should have plenty of clearance room. Found a vendor that sells it for $75 shipped, not bad.
