Their identical to the 1.75" headers and had no problem what so ever. Only thing I didn't like is how the o2 bungs are inset vs being welded on the outside.

Anyone have any thoughts on the fitment of these on an '06 2500HD 2wd?

They fit the same as the 1 3/4 headers. If they fit before these should fit too..

I have a pair on my Silverado and the bung striped out !! now I have a permanent o2 sensor ! just be careful taking them out

The bungs are stupid. Just a hole punched thru and threaded..

They look nice for the price. I'd have a hard time pulling the trigger on them in boston though... the winters here would eat em right up on a daily driver.

Was there any seat of the pants difference? I know thats a hard question to answer... but are you happy with them so far?

i dont remember the 1 3/4 pacesetters being that way? you can buy o2 bungs to weld in cheap.

Plan is to cut these out and patch them and the. Put a bung on down in my exhaust. I have no o2s.
