Hello I have a 06 lq4 out of a 3500 express van.
I?m making a set of headers for it now I?m second guessing my o2 sensor bung location.
Thank you kelly
I see why they charge 2000 and up for a set of custom headers I have 20 hours in the drivers side and passenger side is harder I loose 2 inches clearance from frame from the starter bump .
