ok thank you... if i put the four o2s in the headers and cats will i have a cel or no?

 

im not sure i think im just gonna order 4 new o2s and harness extensions the part numbers are above if anyone has any comments please leave them

 

heres my thread on the longer ones i used for the front.

https://www.f150online.com/forums/ex...those-lts.html

some people leave the rear o2's unpluged and have no probs others have CEL.

i have a tune that i can turn EGR and delete the rear o2's so i dont have them.

As i mentioned my o2 bung is in the collector of the head im not sure if those o2's are long enough to reach the cats.

 

here ya go

thankyou! the casper ones say it comes with 4 female and 4 male.. these just come with 4 male. ( idk much about this ) will i be ok like that? and it says sold in a pair so this will come with two extensions??

 

i ordered the extensions and 4 new o2 sensors... im gonna tell the shop to put my rear o2s up front and im gonna plug the 3 and 4 o2 bungs up on the header tubes permanently beens im running true duals i wont have to worry about the bungs on the y pipe and stuff. then im putting a non foul plug in my cat bungs and not sealing it permanently (beens my o2s will be in pretty fast) then when my o2s come in im gonna change them out using the how to someone posted... sorta off topic but when i pull my wheel off will i need a re alignnment? b/c i am also having bilsteins installed in the front when i do this.

 

unless you replace a tie rod control arm Ball joint/ steering link you will not need an alignment for shocks.

The ones from summit should work they look like the right ones but i see you already bought them.

im confuzed on what you want to do as far as o2 bungs?? is there bungs in the header collector?? if so put them there if not use the extensions and put them in the cats. as far as the rear 2 if your running true duals you can buy bungs pretty cheap and have someone install them.

 

I installed a set of OBX LT and resonators on my sig truck this summer. I had to make up two adapters to make the rear o2 connections.


They made some real noticable gaines with the truck. But they are very very loud. I had a cat back flowmaster 50 series SI/DO setup that sounded perfect.

After LT and resonators the truck is redicoulsly loud. I will be looking for a much quiter muffler to tame the truck some. Fitmet was great, but i would recomend using Ford OEM replacement gaskets. I have a slight tick on my drivers side gasket.

Good luck.

 

yeah i figured it is going to be loud i dont have enough money to get mufflers right now when i told the shop mechanic who i know really good i wasnt using mufflers he looked at me weird lol but i imagine ill get some this summer.. i messed up i looked at the y pipe and saw the o2 bungs and thought it was my header tubes cause it was wrapped up so my fault on that guys i am running the true duals so ill check into the bungs.. unless auto zone has them i doubt ill get them cause i dont have time from now till tomorrow lol

 

well the shop called me today my install wont be done until monday!! unless they open tomorrow which i doubt. he said he got the manifolds off no problem he purposly broke the head of a bold cause it wasnt budging and put a nut on it and got it out what took so long was he had to wait for me to get out of school to ask me a question about the resonators. after that he kept working he usually works late so i drove by abiut 630 to see if he was there and he wasnt so i guess i have to wait till monday afternoon to get it back. hes only charging me 350 for the header / hi flow cat and tru dual install with 4 inch tips so i guess i shouldnt complain. so the videos will have to wait till monday
