    The Magnaflow cats are about as good as it gets most likely. Are you talking about the factory replacement ones or the universal ones? Why not just get rid of them all together?

    Yeah I'm talking about factory replacements. Nah, last time I got rid of them the check engine light came on and I had a hard time trying to get it inspected and pass. lol. I'd rather just replace them with some high flows.

    I think for the price of those, its not a wise decision. I'd just get rid of the cats and delete the codes or get o2 sims. Won't have a problem with emissions then...

    Does it make a difference in how the car will run whether there are cats or not? I've heard that cars run much better with them, but other sources say the extra flow from getting rid of them far outweighs the negatives

    Well I got rid of the cats. and of course the ses came on. Can I just get a friend with a tuner to delete the codes and never worry bout them again or will they pop up again?? Does it require a tune to permanently get rid of the codes??

    Yes, it requires a tune to delete them.
    No, you cant just clear the codes.

    An emissions tune only kills the light. Shit you can do a full cam/head/bottom end swap and still drive the balls off it. Just wont be safe. Emissions... doesnt matter here.
