    your trucks current cats are just fine, hi flo cats are a joke, modern cats are good for 400hp.

    Only reason to get hi flow cats is if you NEED to replace the stock ones or you find a great deal on some aftermarket ones.

    X2....Unless you need to replace a bad cat the aftermarket ones are not any better the OEM cats.
