First things first, I’ve recently started playing with my exaust, currently I have a high flow resonator with split y pipe and twin cans. I really want to go catless but my friend told me I would lose too much back pressure and higher velocity considering I already have a high flow resonator and no actual muffler. Now I looked into this as anyone would and to my understanding, I want a balance of back pressure and velocity, preferably low. Now here’s my question/‘s, if I were to take Out my cats would I lose power? If I bought high flow cats would I lose power? And if not what can I do to get louder without giving up some power? Or even just get a higher pitched sound?
Thank you

My experience is that you shouldn't overthink it. There are plenty of good headers you can buy and two good tuning solutions available. The development work and theory have already been taken care of.
