If I removed my cat, how much better power and gas mileage would I get? Its pretty rusty and looks like it might come apart soon anyway. From what I've heard, the early cats robbed a fair amount of the vehicle's power. I have a 3.8l 231 cc V6 which has 110 hp (which seems kinda low) and gets 21 mpg highway. Just curious about this. I live in Wyoming so smog tests are not a big concern.
