I have ARH LT`s. Ran without cats for awhile sounded great, but you could smell them. So I went to the ARH hi- flow catted x and didn`t notice any change in performance or sound (maybe just a tick quieter) But no more smell. And my sotp gauge said MAYBE a bit more low end torque.

The cost of high flow cats is surprisingly cheap, I personally would recommend the cats unless every last HP is that important to you.

Thats the way to go, I also went with ARH hi-flow catted X
