Ok we have our 99-07 classic stainless headers and Y back in stock.
We are going to do a GP on them for GMFS members. We are selling them for $499.95. But if we can get 15 people to get in on the GP we will sell them for $449.95.
So we just need 15 people to comment to the GP:)

So if I bought the shorty headers what do I do with egr?
IIRC your 2006 doesnt have egr. The headers should come with a block off plate.

Still WAY cheaper at Speed Engineering.
Exactly what I bought. Got tired of waiting for LPP to get down to a reasonable price.

Although, apparently LPP headers are made slightly better. But who cares, they're under the damn truck.

They should work, the only thing that would have to be changed possibly is the y pipe b/c of your lift.

It was well worth it. Do longtubes, mine bolted up to factory system

when you say it was worth it? what was worth it?

do you actually get that much more performance? or is it the sound?

It was worth the price for the speed engineering headers I bought. The truck does sound mean but a little raspy sometimes. I'm gonna swap mufflers to help that part.

I'm sure I gained top end hp from the headers as well as low end torque from the tune. Plus, they look damn cool

Yep, bolted right up to my cat back system. The fitment wasnt 100% perfect due to china products, but with minor adjustments, they fit great
