Hi everyone, I have been reading the forums for about a week and decided i should join up. I also have some questions about some mods. My stang is a Green 97 Auto 232. Just about graduation time so i will be getting some money and i want to put a new exhaust on my stang. My friend has some an extra stock duel set from his old 96 gt stang that i can have. Should i just buy some flowmaster 40's and weld them into place of the stock ones? I plan to get the pace setter converter kit unless you guys know an easier way. I would also like to burn out or gut out the cats. What do you guys think about this? I live in IL so i dont have any tests, but what will it do for my engine? Ive been driving for awhile with bad o2 sensors but i replaced 2 after the cats, but it still says some are bad, do i have 2 before the cats, I can't really tell. One last question, If i gut the cats what can i do to "Trick" the engine into thinking its running correctly. Thanks
