SW headers with cats check engine light issues

[Toowired]

Can anyone with the stainless works (or other brands) chime in about any check engine light issues they have had since installing them?
I want to go to a long tube header with cats and am a little nervous about the computer throw a check engine light for catalytic efficiency with the new headers.
Thanks for your input.

Hey toowired, with an addition like LTH you want to include custom tuning. We can help you out with that, if you would like. Here is the link to our MyCalibrator tuning interface and a YouTube video showing our gains tune only.

i've put about 10 complete 30+ minute drive cycles on mine since installing last week. no CEL, and OBD tool doesn't show a 0420 pending either, so the 200 cell cats are adequately converting
if they weren't, i was planning on throwing one or two of these on to pull the 2nd O2 sensor(s) out of the flow when it came time for an emissions check in a few years:

do you have it tuned? you'll get a check engine if it's not tuned.

untrue. i am waiting for my lund tune still, so i've been running on the stock configuration for a week, lots of drive cycles, couple hundred miles - no CEL. of course, i've watched my AFR running pig rich all week, so i'm sure i'm not doing any favors for the longevity of my cats!

I have high flow cats. I have a CL on right now. I am waiting on a tune with the supercharger to turn off the secondary sensors. All the secondary sensors do is tell the computer the cat is working.

Thanks for the info. I was wondering about all your custom tunes. Are these just tunes you have done on customer cars with the same mods and put them out there for free as long as I own your tuner?
