HELP PLEASE!! My 05 toyota (4.0) is throwing the p0420 and p0430 codes, my cats are bad, they've been tested and that's what it is. Right now our biggest concern is MPG's it's dropped about 5mpg's. Now before I spend $$ and replace the manifolds/cats I've been looking into other options...I wouldn't mind a performance upgrade and exhaust tone upgrade. I've been looking at headers and 02 sims, anyone have experience with these? A particular proven company? Did you get restored power and mpg's? Thanks a lot guys!! I'd still like your input if you only did one or the other!
