Well,,I for one must of put the worst possible combo on my truck.
The first thing I ever did to my truck,( back when it was completely stock) was put a true dual system on with Flowmaster 40s( witch every one say they suck!)lol
I never felt a loss in power or torque. It sounded great and looked good and that's what I was going for.
It's an exhaust system for shi*s sake. What are we talking here 5 or 7 HP MAYBE?

I tried it cat less once. Factory everything , just No cat's.... Also replaced my stock muffler w/a 50 series Flowmaster. I lost what felt like MOST of the low end and it didn't sound good.
Then I installed new forward cat's . Those little cat's made her sound like a GT - I liked that sound. You know how the older GT's sounded lol. - I got some torque back. The stock tune couldn't handle that much flow. Like I've said many times , I'm not sure how much torque/low end loss can be dialed back in on the dyno - Stock motor with a High Flow set up - How far can go with it ?
Man I'd like to see some numbers.
BTW -I'm thinking you did lose some phil - It just didn't sound like it
If duals did us any favor's in performance department for a stock motor set up, I think would have heard about it long ago.
I've heard some awesome sounding duals before tho..
