Has any one removed the cats with stock manifolds and experienced any negatives. I am thinking of having them removed for some extra power and I understand I will get some codes on the dash but I will be getin headers and cam and tune before I get emission tested again so thats not a problem. Did any one lose gas milage do to O2's not working like factory or have any poor running? Thanks in advance.

I did it when I still had stock manifolds. I put 02 sims in so I saw no neg. And it actually sounds pretty damn good with the stock muffler and no cats. It really woke up my exhaust tone! Your mpg will be effected if you dont put in sims or have the code deleted.

Thanks for the quick reply. If I Buy the O2 Simulators will I beable to reuse them for when I do my headers. My guess is yah but just wanna double check. Thanks again.

yeah 02 sims just fool the PCM telling it the cats are still there. They can be used, used and used again, lol...... They really cant get old

So after you put in your cam and headers and get a tune to delete the codes you can remove them and sell them. I got some new ones I will sale ya, if you are interested PM me
