Hey I got obx header with y pipe (fake cat) 2 days ago. I was going to install it tomorrow. Also I already called Allen Nelson to retune my pcm for my header adjust emission and cover 02 sensors... But The pcm is ship out today wont arrive UNTIl next Tuesday. I wonder if I can ahead put header on it and drive till pcm come in I can swap the pcm. Or I should wait? It will come light on if I drive with no swap pcm? I want to do things safe before I ahead install. Ill take all pictures when Im done and show yall if you like to.

 

you can install them nothing will happen to the truck your check engine light will come on but i wouldnt hot rod it just to be safe i put mine on with no o2 edit and it had no muffler either for one day and it did fine just the check engine light came on and thats it

 

You will be fine with the install and no retune for the moment! The retune in on tuesday is no problem...the truck will still run fine for the moment. You'll be amazed how easy the install goes!

 

I did my 6.0L swap and header swap all together. Amazingly enough, I drove the truck home without any changes to the tune and never threw a single light. I had the OBX's as well even. You'll be just fine

 

I didn't have a retune for my headers for about a week too and it ran just fine. You can go ahead and slap those babies on

 

 

put em on and enjoy

 

You will like them. Go ahead and put them on. You will be fine.

 

Good! Im so excited to put on and want to see the feel different. I have hooker acochamber on it. It supposed to be louder after with OBXs...

 

Hey I can see my obx and ypipe with fake cats show that 4 bungs holes. I want to know is my stock o2 senor wires able have room to plug in? It seem long pipe that where 02 sensor blungs are. Let me know.
