6.0L Cat

6.0L Cat
Here in the great state of CA(joke) we have to smog our diesels. I was thinking of gutting the cat and putting a cat back 4in exhaust on the truck. Has anyone ever gut their cat? problems, things to look for? etc. Anyone have any pics of a cat internals? I have a about 190K on the clock now and I'm sure the cat is plugged up a bit. Just looking to make the 6.0L run more efficient.

I gutted that bit$* as soon as I bought it lol. I just rammed a pipe through it with my log splitter it is very tough stuff. It looks like very small honey comb. No problems to report. There is also a resinator or smething on the down pipe that I cut open looks like a motor bike exhaust inside. And the muffler had to come off.

I'd check out the Magnaflow real close to be sure it's legal in Ca...they have to have an E.O. # issued by the state.
Test pipe...86 bucks

Cats
I checked out those Magnaflow cats, they are 'high flow' and are available in differing sizes of pipe (IIRC 3.5" TO 5") so are an easy install regardless of exhaust tubing size.
Unfortunately, as Steve points out, they are currently not available with a California E.O. #, so are theoretically 49 state only.
Not saying one would not work, but a savvy smog guy may notice it is not OEM, and start looking closer.
They are a nice piece though.
