Bummer guys, I tried putting these things on last night from the top and then from the bottom on the passenger side. They were about an inch off from fitting. I couldn't get the ports lined up on the head to the header. The header rested on the frame (primary tube #4) and wouldn't allow it to go down further. I guess these don't fit 03-07 trucks afterall

I'm working with speed inc right now to try to get the headers exchanged back. We had an agreement that if the headers didn't fit, they would accept them back in return. We'll see how that goes. In the meantime if someone wants a deal on these, I'll hook them up. These technically are for a 2008 Escalade Part#: 6753. I have these sitting next to me in the box right now and I can ship immediatly. If you want a set of these for your 07+ GM SUV, you'd have to wait a month to get them and pay $150 more than I'm selling them for.

Man that sucks. I guess you didn't even try the drivers side?

 

so are you gonna try a different set of headers once you get rid of those? Just wondering what your next step is going to be.

 

I didn't even try the drivers side to be honest. I just boxed them back up. I don't know what my next step is yet. Manifolds and stock y pipe maybe. This **** is getting expensive!!!

 

Unlucky, thanks for being the guinea pig for the Kook's on the NBS, those look like some sweet headers

 

Give these a shot so I can buy them too if they work. They look alot like fbody kooks that we know fit.

Uhm, no thanks. I want a stainless header that's going to last years, not coated junk

 

Do you have an exhaust guy that is hooking you up? cause I know an exhaust guy in coon rapids that does mandrel bending.

 

I doubt I can afford Tim's pricing.

 

Yeah he is a bit pricey. Well good luck with the quest for some LTs.
