Cats or no Cats!

[Special K]

So I spoke with the diesel tech at the Ford dealer here in Greensboro today. Trying to find out what he suggested for my 05 6.0 litre. I asked about the EGR delete? He said it was not a bad idea, and probably worth the money to have it done. Which I was amazed he said that , but seems like a pretty strait up guy. I then asked about any upgrades to, such as exhaust and programmers. He said not dropping names but run the Superchip, it seems to be a better unit and has taking off alot of the others do to issues. I wasnt too sure what that meant. On the exhaust part he of course suggested not to take that cats off. Just run a larger pipe from the cat.
So what are your guys and gals take on this? I dont plan on racing this truck or nothing to crazy, but I work for John Deere and I pull a trailer quite a bit with equipment on it. Like to pick up some fuel mileage and some power.

No cat is fine. I just gutted mine. However, if your state has emissions testing, no cat will fail. Also, if you want to run a programmer to improve milage and power, go all the way. A HUGE number of members here run and swear by their SCT (I'm one of them) SCT does a good job with transmission tuning which improves the life of your trans (with proper maintainence, of course)

Oh, and

I was thinking of gutting mine. I kinda want to keep it just in case, so i will probably delete it.

Yea don't ruin an expensive cat by gutting it. Just take it off and replace it with a pipe.

Just buy a cat delete pipe for the factory exhaust. You can find them with a google search. Just unclamp the cat and replace it with the delete pipe. Put the cat in the corner of your garage out of the way so that if / when your state does start emissions testing you can slap it back in for a day to pass the test then just remove it again.

That's what I do.

Took my truck to a good 'ol boy exhaust shop when i was in texas and he welded flanges on both ends of my cat and my 4" pipes. welded flanges on some straight 4" pipe, 8 bolts and the cat goes back in for emission testing. Simple, quick, and easy!!! It made a big difference in the sound with the banks exhaust!
