I have a 14 ram hemi and I have a cat back system on it already but I wanna go louder should I get high flow cats or hollow the cats on it out and what kind of headers should I go with. Also will putting high flows cats or hollowing them out throw a code on the dash.

Yes they may throw a code. You may need the 02 spacers to create the same flow they are used to getting.

You will need to change the o2 sensors with the spacers. The programming has a set parameter that will not be met if you do this, as well it is not legal to do. Some states it will cost you majorly if you have to do the eg system test for inspection.
