The way I see it, it's an environmental thing. If you already took out the cat, then it's useless and not helping much anyway. Might as well get rid of the extra clutter.
I far prefer the clean sound as well. Bike only pops on very hard engine breaking now. Imo, excessive popping just sounds like an out of tune bike.
