Default Anything wrong with have one hi-flow cat on the I-pipe??

Is there anything wrong with having an off-road Y and just one hi-flow magnaflow cat right after the Y on the I-pipe? What will happen? Pros? Cons? Thanks for the help.

the only thing it will really do for you is quiet it down a little. the reason they are up close to the headers is because they are the most efficient the hotter they get

If you are going to put something in the I pipe put a bullet muffler in it. It's pointless imo to put cats in the I pipe.
