I am looking into purchasing a set of the headers and just was wondering, is the check engine light always on, thats what i heard earlier when they first became available, but not sure if it is true, thanks
Well like I just said I never get the CEL and I have the DT headers. Also I dont know what you mean by how you drive depends on it. Cause I red line the sh*t out of my 4 banger and I drive it like crazy. I dont get the CEL? I know slytuna said he never got it either. Maybe its cause we both drive the crap out of our 4 bangers.Yes, you will get a CEL since the O2 sensors are going to detect the absence of the 1st Cat. How often you get it depends on how you drive. I sometimes I got it after 10 miles of driving, sometimes after 50, sometimes right away after resetting it. There's no decrease in performance from that particular CEL, only the annoying orange light. The truck will continue to work in a normal mode.
Also, there's a pretty easy fix with sparkplug anti-foulers. I did that on my truck an I haven't gotten a CEL ever since.
Hope this helps!
I had enough room to use 3 of them. Use the anti-fouler on the 2nd 02 hole, the one after the cat that was removed. The first O2 sensor is for the A/F ratio, you don't want to mess with that.Also, there's a pretty easy fix with sparkplug anti-foulers. I did that on my truck an I haven't gotten a CEL ever since.

how did u get it to fit. on my truck i dont have the room to be able to mount an anti fouler in there the o2 sensor will hit my fire wall
Yes, not the one that is on the header itself but the one right after it.so your talking about the o2 sensor not connected to the header, the one after the 2nd cat? and that will solve my check engine problem? ALSO should i start with 3 anti foulers or should i start with one and go from there?
