Exaust: back pressure and velocity
Hello, I’m new to the car scene, and trying to best my knowledge. So I bought my 2013 FRS not too long ago. I’m new to this website so my apologies in advance for anything i may be doing wrong and/or nooby terminology.
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
