I've heard of people putting pacesetter lt's for the nbs on the nnbs with minor modifications. I've had headers on a few of my other trucks and hated them because I couldn't keep them from leaking. How are these for installing and sealing? I'm not worried about doing the fabrication to get them to fit right but dont want to go through all the work if they are gonna leak and annoy the crap out of me!!! By the way my truck is a 4wd if that makes a difference. Please let me know what i'm up against here!

 

i don't think there is any modificastion with pacesetters. installed them before on an 07 nnbs.

 

Hey i Ordered a set of pacesetter LT's for my nnbs 07 sierra 4X4 and they will not fit! Well the passenger side is perfect but the drivers side there is no way. The tube for the #1 cylinder will not clear the mount for the front differential. On the other hand they will probaly work on a 2wd pickup. The differential mount is the only thing stopping them from working on a 4x4.

 

From what I hear shorty's dont give you much of a gain but I cant find anything for longtubes. Anybody know of anything?

 

my bad i forgot to mention that installation was on 2wd nnbs's.

 

The headers I got were for the AWD/4wd so hopefully they will fit

 

sorry the ones i had were for a awd 4wd, didnt fit!

got these from tbyrne, supposed to fit 2 and 4wd nnbs

 

Anybody know if the obx headers will fit on an nbs 4x4. I'm searching for a set for my rcsb 5.3 4x4.

 

will probably fit 2wd, not 4wd nnbs
