if your main concern is being able to run more boost (based on the cars in your sig im assuming so) go with a catless DP and leave the rest alone for the time being.. Your buddy can always hack out the rest as you mentioned. muffler delete will likely be too loud, but if you are down with running straight pipes go for it.. my recommendation would be replacing the DPs with catless ones and gutting your secondary cats.
