Hmm... that's a good idea. I've got a 'smog' tune... but haven't actually ever run it to see if it smokes. (Have 6 mo to make sure everything is in order.) Can their obdII scanner detect the presence of a chip, even if it's running a detuned program? I kept the cat off my stock exhaust just in case - need to make a 'test pipe' adapter for it, although I thought the '99 shouldn't require it. I'll check with one of the cooler local places before then and report in here in case it helps anyone else.
Once I get flanges on the stock cat, maybe with some adapters for the MBRP - happy to loan it if someone's in need. (The only 'relatively affordable' ca legal cats i've heard of are Magnaflow... and I've yet to see a vehicle run right with one of those things in the way of the exhaust. )
I'd really really hate to have to find a 'spare' set of stock injectors to pass smog. I'd rather get an east coast DL, use a relatives address and register the truck somewhere else.

I'm sure that's going to depend on where you get it tested, and what the knowledge level of the tester is (or if he cares, for that matter) and what he uses to read codes. This guy just used an over-the-counter code scanner...never hooked it up to a computer.
The place I went to is a test-only facility. I figure they hadn't seen too many diesels there, because he was referring to his book quite a bit.

If it had a cat from the factory, it needs it. As I understand it, some '99 did, some didn't. There should be a sticker under the hood, usually on the radiator support, and it will say Catalyst or Non-Catalyst.
Seems to me there would be a black market for new stickers.
Folks call me Bill. Why, yes, it is a 6 liter. Your jealousy is showing.
Haven't had to smog the '08 yet but it sounds like a switchable system will be easy to work out.
My mileage for a diesel is horrible, so I can't wait to delete dpf.
Figured I'd get to it after 100k is reached.
Any thoughts on who would have a nice system besides the obvious Banks
Just don't feel like taking the chance on a drivetrain warrantee ( read expensive ) and being turned down cause they bust me by detecting the reprogram on the computer.
From what I read they are pretty good at that.
