If your not doing the work yourself, go to a muffler shop & tell them you want to switch to a single hi- capacity. The pipe diameter should go up coming of the Y connector. The first H/C Cat I had installed, failed prematurely because they didn't go up a size at the Y.*Post your own thread next time. They're free!
