There's no quick/easy/cheap way, or Toyota would have already done it, and removing the cat conv is certainly not going to do it.

What will removing the cat conv. do?(as far as negative effects). I don't live in an inspection sticker state, and i've removed the CAT on almost every Vehicle i've owned and notice a small improvement in both power and mpg... just curious as why that wouldn't improve mpg/power... also there is no O/2 sensor in mine (I wouldn't remove the CAT if it had an O/2 sensor)
