A few guys on xru have done some extensive muffler swaps and even combinations to get rid of rasp....especially after headers and cat deletes.
Well this TW guy has always been on a mission to delete rasp...
OP, I am currently running an aero 2525 setup with headers, cat delete, the whole bit. I would suggest that you add in a resonator to get yourself out of the Honda Civic range, but since you are looking for more sound a muffler swap might be in order. I will put my vote in for either an Aero 2525 or a Wicked Flows muffler. I'm not sure which model MF you have, but I can almost assure you that either one will be louder. I personally got over the rasp of just the AT2525 in my truck rather quickly and added in an 18" resonator later on down the road. I would recommend that everyone do that, but some like the ease of only doing it once and go with the 2525xl which has a built in resonator.
All in all it really comes down to what you like to hear. I am happy with my setup though I will admit it does drone a bit, but nothing that is mind numbing or can't be overcome by the radio. My tires make more noise. I recommend checking out some videos on youtube. I even have a few of my setup on there (same username). If you have any detailed questions, feel free to pm me.
