My 93 S10 is in need of some help. The CAT I think is clogged...piss poor mileage and no muffler. What will happen to the poor computer if I put straight pipes and one muffler on it? O2 sensor? I have heard of some just dumping fuel into the system cuz things aren't up to spec. Any ideas? Thanks!! SK-15 J**P...it's whats for dinner! Roads? Where we're going, we don't need any roads! If it wasn't for bad luck I would have no luck at all!!
