Would putting the headers on with the ORY be okay to run without the the tune to tune out the post o2 sensor? Or should I not even bother until I can afford the tune and headers at once?

 

I'd do them all at once. Without those sensors tuned out the truck will run pretty bad. Order headers now, get them in, save and get tune. simple as that bud.

Oh and with the Texas Speed stainless headers you'll have to take out the EGR valve. Get it tuned out as well and the tuner can adjust for it bein off the truck. You'll also need a expansion plug to plug the hole it leaves on the intake manifold for no vacuum leaks. They're 4 bucks verses the 22 dollar plug GM has.

this is the one I used.

Yeah i'll probably order the headers now since i see that there on sale. So did you actually remove the EGR or just the hose that runs from the EGR to the manifold?

 

Removed the whole thing. No sense in havin it there while it's not workin ya know. Still have to get it tuned out but the Egr only works in first take off I believe so it's not that big a deal

 

So was going to order the Texas speed stainless with the pacesetter ORY and they said that either of there ORY withholding fit a 4 wheel drive cause the transfer case gets in the way. So now I'm not sure what to do now. Anyone know if it.actually fits a 4 wheel drive? Texas speed seemed to tell me otherwise.

 

I am 4wd. It cleared everything in my truck just fine

 

You used the pacesetter ORY with the texas speed stainless LT's? I thought you had true duals?

 

Yup used the pacesetter ory and tsp headers. My lift may have affected the fitment but they fit great. And I haven't gotten around to changin the sig lol

 

ah alright yeah there saying that the transfer case is in the way and thats why the ORY wont work on the 4wd but if your saying you didnt have any problems ill give it a try.

 

Just ordered them. What muffler you running now country_09?
