As soon as I pick an engine out I will.

 

i do have the obx headers for my dd 01 sierra 5.3l Z71 and i noticed it ate all my 02 sensors am i going to have to buy more cause i do have to go thru emmisions does anyone have a cure for this or will i have to buy all four 100$ sensors every time i have to go thru emmisions

 

I'm a bit confused...
What do you mean, "it ate all my O2 sensors"????

I have aftermarket replacement front O2 sensors, and have the rears deleted via my HPTuners tune. No issues whatsoever in 14 months (so far) of use/abuse. I swapped headers at the same time I swapped sensors, and only because my stock sensors had over 100,000 miles on them did I change them.

Two weeks ago, I passed my state emissions test, which checks both the OBD and a quick visual inspection. The resonators look enough like cats that there was no question of pass or fail regarding the visual part of the test.

 

FWIW, I bought mine from proautoluxury & the box says DNA Motoring.

 

well what i mean by "ate" is they dont work there burnt up well not getting hot enough. they dont do any visual testing by me just hook the obdII and it fails the oxygen test and an evap test. now that i know i can delete the evap i can pass the emmisions just gonna do it after the holidays and i did delete all the o2's, and i do have the hptuner

 

hmmm. That's at least 3 different names for the same seller, which is odd, but I haven't heard of anyone needing any warranty claims or exchanges either. That might be why they have all the different names...if they have crappy customer service on other stuff they sell, maybe?

 

what? i dont think you want to delete ALL the o2 sensors dude... the front ones are what determines your a/f ratio

 

Somehow I missed that post. I'm still not exactly sure what S10W5133RA has or hasn't done to his tune regarding the O2 sensors.

 

Well more thanks to you Rel3rd, I'm definitely going to have to order these instead of the pacesetters. Performance on a teenage budget isn't the easiest thing in the world.

I'll have my friend who will be installing jot down some notes from your installation, so he knows what to use/replace etc. And I'm sure his shorties will be very jealous of the stainless LT headers.

Good to know that they ended up too loud for you, no such thing for me


I'll be gettin them ordered asap, and will let everyone know what happens.


Cheers to rel3rd and everyone else confirming success

 

You're quite welcome. Thanks for the kind words. I'm happy to help if/when I can. Good Luck with the install.
