Without doing the headers, which exhaust setup would make the most horsepower? I'm thinking about removing the 3rd cat, having a single cross over 3 inch x pipe put in and weld it to 2 1/2 inch dual pipes all the way out to Dynomax mufflers. Would this setup make more power than replacing the 3rd cat with a 2 in 2 out Dynomax muffler and running 2 1/2 inch dual pipes all the way out, straight pipes with no mufflers? Basically I want the setup that provides the most power... any ideas?

I was thinking of doing the 2/2 but I heard it was way too loud. You could also put a 2/2 in place of the 3rd cat plus 2 more mufflers in the back. The 2/2 acts as an X. A few people have done that.
I would just delete the 3rd cat, put an X-pipe, and mufflers. And headers
