finally pull the trigger and bought the headers for my ISF, so far only other mods I have is joe z intake and apexi throttle controller. still on stock exhaust, how much who should I expect with only this intake and headers? close to 380whp?

also would the headers come with the o2 sensors defouler or I have to buy those separate? and if I do have to buy them what brand or style seems to work the best with the F? so I don't get any check eng lights or anything!

thanks for the help guys.

 

For the sikky header they will send u the o2 simulator that eill cover u but when u install these make sure the wires n o2 sim is in good condition if the o2 sim is defect oh boy situation
And for the whp
U really need to dyno the car
And car need to run the new mod so go for dyno do the few hard pulls n let us know what u get
I get 396 or vert close to 400 whp with joe z intake with drop filter with joe z exhaust n sikky header

 

I have an apexi throttle controller you can buy. LMK! used maybe like 10 times lol

 

thanks for the info, I would take a good look at them cables then before installing!!

I will go to the dyne for sure right after is a get 380whp or more I'll be happy…

 

I already got mine!! thanks anyway.
