I did something similar at first and had the same silly ricey sound.

I went with some Hi flow cats, since we can't do headers on the lfx. Straight Stainless pipes without crossovers to the rear, where there's Borla touring mufflers.

Seems like you're looking for loud. I'd recommend doing the Hi flow cats, and putting in and in-line baffles. The baffles would act kind of like a resonance chamber without cutting out too much sound. Bigcitythunder.com makes 2 1/8 ones, and freddomperformexhaust makes 2.5 inch ones. You could slide into the pipes to cut down the rice.

Here's what mine ended up sounding like...
