Would like to start my H/C/I on my 06 RCSB 4WD Sierra, but currently waiting on 1 3/4" LT headers.

Besides Speed Engineering (they are out of stock) 1.5 months or longer since the dates typically get pushed back.

Researching other vendors such as Texas Speed and LPP, which are supposed to fit on 4wd applications. I have not found confirming reviews, more or less the opposite, older posts have shown clearance conflicts with the front driveshaft.

Dynatech, Kooks and ARH are out of the picture due to cost. This is a weekend toy not a race brick.

I know I can put on the LT's later, but would rather knock this work out in a weekend since my time is limited this time of year.
