It won't take too long for you to find a used pair of DT LTs here on this site. I bought mine here for less than half price. And a little surface rust doesn't matter if you're going to powder coat. The baking and sandblasting gets rid of it NP.
If you don't hear anything for a few days, just keep bumping your thread once a week or so.

Good luck!

What gains did the headers give you ?

They're not on yet - still getting a powdercoat. But with the Uprev combo, I'm expecting a ginormous butt-dyno gain.

When will it all come together ?, will you do a before and after the fact test ??

How much was the uprev ?

The install will happen this coming week at a local Meineke shop. Uprev is $500 ($700 if you want to tune yourself, the $500 version comes with 3 custom tunes from Uprev)

I doubt I'll be able to do a before run, since my truck is in limp mode due to the catastrophically bad e manifolds and cats.

Are they legal in CA ?
any idea How much to get them installed for on a 2006 4x4 cc

Not strictly legal in CA, but there are workarounds.

Install ranges from $400 to $800, give or take, and depending on where you go.

I'm no expert, being as I live in TX. But there are ways to clear the codes with spark plug defoulers.

And doug Thorley's website does say:

Q: Are your headers smog legal?
A2: Yes!!! All of our headers are smog legal in all 50 states. The EO or carb number is welded on each header.

But I'd look into it further.
