Does anyone know if taking the cat off of my truck will improve performance or will it totally screw everything up with the o2 sensor.

Ugh, sorry, I have a 93... I didn't even think about how different that would be. Things are simplier on 1st gensGAS10 said:i have four o2 sencersand one of them are after the cat. i have a 97. 4.3
You could buy a high-flow cat, but I'm not sure what kind of increase you'd be looking at. But even with that, since yours is a 2000 you can't change the cat for 4 or 5 years unless the cat on your truck goes out.GAS10 said:i thought about doing somthing with my cat so can you tell me what i can do that wont throw my comp off.
