So i just got done installing speed daddy headers! Took me 14 hrs!!! But i have many questions! I dnt have either o2 sensors does that affect performance? My front headers were a bit bigger than i thought and the middle of the 3 is leaning up against my fan! Doesnt look that good but it was the only way i made em fit! Anything future issues i may have? Also i didn't connect the last part that came wit my headers to my res so its super annoyingly loud! I didn't wrap my headers i just painted them wit high temp paint also. Any advice helps thanks in advice

 

Im pretty sure u need the upper O2 & is it by the heat shield on the fan? & there stainless so u really didnt need to paint em

 

The first o2 sensor tells your PCM how to adjust the air/fuel ration. Without it you are just running open loop all the time which means your car is just dumping as much fuel as possible.

 

Yeah you need that upper o2. I did not install the rear but I'm also having the code deleted in my new PCM from ZZP.

14 hours sounds about right lol. Took me from 10 am. til 12 p.m. but I also had to let my Monte cool for a few hours so actual install was close to 8 hours. Still a major accomplishment if you ask me!

My front header is also touching the fan but I've seen no issue with it. If you really wanted to you could switch to a slimmer fan set up but I don't think it's necessary. Also, not sure that I would have painted the headers LOL? You didn't like the stainless look? I personally love mine even though it's all kinds of crazy colors now

 

I installed my speed daddy headers in about 6 hrs, Mine didn't touch the
fans .., I removed my headers after 2 months to much of a drone noise..
On the highway ..

 

I looked up install time and it said 6 hrs so i figured that's how long it would take. Took me about that long just remove them! Lol i did like the stainless look but i knew they'd turn crazy colors so i painted em blac lol my upper o2 wasn't long enough so i have to buy one now! Can i buy one from autozone maybe?

 

Buy the o2 extension from ZZP.

 

Here's what I got from zzp...
LINK:Easy Performance - O2 Extension Harness #EP-O2EXHN

 

Yea i was lookin at those how come they are way cheaper than other o2 sensors I've seen??? And what option do i go with? Cuz they have option a b or c?

 

Or u could do it the cheap way & get some wire & connectors & extend it yourself just do one wire at a time thats what i did on my GTO
