Check engine light with headers?
Check engine light with headers? So i have just ordered Pacesetter LT's (w/emissions) and a pacesetter Y, after i install them will i have a check engine light on?? If yes, how do i remove it? With a handheld tuner perhaps?
I don't know what that means.
Heres how it goes whoever does the work.
Install everything.
Start it up and let it run, everything gets up to temperature which burns off/cures any coatings in the headers. Sometimes they can ruin the O2's if you're curing jethot or have plain with a bunch of cosmoline in them.
After they get nice and hot the light will either be on or not. Reset the light. Sometimes several times, sometimes never.
I can't predict whats going to happen just giving you ideas of what can.

If you kept the AIR system then you will not have a check engine light for that.
The only engine codes you will be getting will be for the rear o2 sensors...but the handheld can turn that off. It can not turn off the AIR codes.
No, that will not set off any codes.
But dang, I love watching fresh headers burn, and the smell! yummy.

if running an ory you will need to buy some 02 simulators for the rear o2s . also deleting the AIR/EGR will throw a code . this was one of the first mods i did back in the day . what i did was sent my computer off to wait4me and had him delete the rear o2s and AIR/EGR . look him up as he does great work for a mail tune for a good price .
with a lid , mac mid headers and duals i put down 348rwhp on the dyno . this is with a ls1 intake and everything else stock aside from ahveing the computer reflashed .

But i just ordered the Y pipe itself without cats, nothing was stated that it was in fact off road, i was hoping to use my stock cats... Can i do that?
If someone tells you differently (again) it doesn't matter, when you get all the stuff in front of you it will be very obvious.
oh well, i'll see how it goes...
