These issues have persuaded me to look into the 18 vs 12 resonators..probably will end up getting hfc and more at some point, try to keep the decibels down.

Have no idea why lol, It may have changed the velocity of the exhaust because longer intake runners? Regardless, it was the first thing I noticed when I reinstalled my stock manifold. I was butt hurt because it came back and did not sound as nice haha. Inadvertent benefit.18" resonators will give the TP's and headers a nice balance. I understand people like loud, it will be loud and aggressive without being obnoxious. MY Tanabe exhaust was rated at 93db though... pretty quiet when I'm not on the throttle. The second I tip in the gas, it opens up a serious can. I couldn't imagine LTH's/TP's with 12" or no resonators at all. I would purchase an insurance policy on my ear drums.

Lol another one of these threads? Well I'll chip in then. I'm running:
Stillen Gen 3 CAI
FI LTH
FI CBE non res'd w/ CF mufflers
Stillen lightweight pulley
Uprev tuned

Not really any rasp (and by rasp I mean the sound of a rusty civic that's powered by an angry swarm of beezzzzzzzz) although it is pretty loud. When I go to work in the morning my exhaust rattles the pictures on the walls of my neighbors house. Luckily they love my car and don't care, I've become their alarm clock lol.
