I appreciate the thoughts from everyone, and yes, I am looking for better sound and performance. The thing is that I'm worried about gas mileage, especially in this day and age. I want to know how much my mileage will be effected depending on having cats or not. Before one of the cats was sending bad signals to my sensor, my car's average range was 300 miles both city and highway combined. Now, it's only around 230 miles. For me, that small difference in mileage does add up, especially in this freaking city. PNISSHR's suggestion for either getting sims for the rear O2 sensors, or just turning them off, looks like something I would have to do anyway, but I appreciate him bringing it up. Nevertheless, it will be a good while before I begin doing this anyway.
