Catco and walker are big names. Walker is a huge aftermarket oem exhaust company. Usually everything is direct fit. The cats we use ARE NOT high flow cats, they are just universal cats. I've done some research on this, you have to look at the cell count in the substrate to determine if they are high flow or not.

so i have a question, i have an 05 with a 5.4. i had the same problem with magnaflow telling me i have four cats under my truck, which i do not. so will either setup work? the 4 cat or the two cat? whats better, will the two that everyone is mentioning on this thread work? would they be best? and how bout with headers? also i have to pass emissions test crap here so that may make a difference. thanks.

As far as emissions, stick with a cat with a 300+ cell count.

Just an inch or so. Not too close, not too far.
94106s are louder and cheaper ($67 ea. )since they're a smaller cat ( takes less stainless steel to make them ) The 94306s are 30% quieter than the 94106s and are T-304 stainless ( shiny ). All depends what you think you would more prefer, the loudest sound close to cat-less, or a louder sound but not too loud.
