dc has been around a long time. my wife had a dc header on her ricer 13 years ago and it was a top of the line manufacturer at that time that was producing aftermarket performance parts. im really tempted for the price.

 

Its got a merge collector. As for the O2's. Theyre probably doing all they could to keep them as close to stock position as possible.

 

If they have a set left by thursday I think I will see if they fit a Z71

 

these or my togs hmmmmm

 

The location of the 02 bung on the pass side header would be right against the frame????

 

as long as they fit and the sensor does not hit that is all that matters. Maybe a pain in the *** to change them out but really how often do you do that?

 

I'm talking about how the sensor is halfway up a single pipe, and not in an area of "scavenging" for a better reading.

Or is a single pipe/port a better area for a reading




looks like it's level with the starter, on the frame side.

Its not like people that are into performance are really going to use a narrow band O2 to get our trucks tuned. Having it in the collector is basically just going to average out each bank. Its not going to save your motor if there is something really wrong by having it in the collector. I would just be worried about the frame clearance.

 

it would be easy to plug them and weld a bung into the collector if that is what you wanted I mean for the price you could do a few things to them and if they work well you still could save a few bucks IF you are willing to to a few thing to them or live with how they are. I just hope they clear on my truck.
