I just bought a set of Pacesetter LTs and their ORY for my 2006 Silverado, but before I could install them, I was hit by a dump truck and now my truck is totaled. I am going to buy an '07 Sierra Denali (nnbs) with the 6.2 V8 (L92 I think) and am wondering if the headers would fit it? I know they will fit the L92 Heads, but I was wondering if they would clear the AWD stuff and the frame? Any help would be great!
