As mentioned many times before, they are not 'cats', the are simply 'resonators'.
Read about them again.
Gains would be as typical as with any 1-3/4" /primary long-tube installation. I'm guessing 15-30hp gain. Could be more, could be less. How's that for a stupid answer?!? LoL, ...
You can find aftermarket hi-flow cats all over. Need to make sure what size you'll need to tho, & then find a place to get them in the line-up in the y-pipe.
What US-state are you in? Do they check for that in your location?
Fitting cats in place of the resonators would require more work by the install team. Cut/weld time to take out resonators & put cats back in.
You'd be better off in the long-run just to look at the more standard Pacesetter brand maybe?
