Are you talking about using straight pipe to replace the cat? If so, it won't hurt your motor directly. The O2 sensors won't get a right reading and it'll make it run rich and by that diluting your oil and putting more dirty crankcase air back through your intake. So you can go with an O2 simulator, but they will stop working after a short period of time. Your best bet is a high flow cat.
