I have read where a few members are extracting HUGE power through using headers and bigger exhaust to let these things breathe.

My question is, how are people bypassing the O2 sensors or keeping them freaking out?

 

O2 simulators keep the CEL at bay and yes headers yield 40+ whp on the IS-F!

 

Here my car before and after sikky headers and a Joe z pts.... 60whp and 30tq across the board. My injen intake was on for both the base run and after full exhaust.

 

^ great freaken numbers darbs.

Sikky & PPE make headers for our cars. They include simulators/conditioners for the 02

Great Thread and question.. I have the Joe Z PTS but was thinking about adding the headers to complete the set up, im worried about throwing CELs too, will be following the comments here for advice and direction

 

I purchased headers and have had them on for about a week now. I love them. The combo of a JoeZ exhaust and PPE headers are great. And I'm sure it's the same with Sikky. It's like SPORT mode is now normal driving and SPORT mode post-headers is just exhilarating.*
I'm lucky in that I live a state away from PPE engineering. I knew that my car wouldn't throw a CEL if the company that developed the headers, installed them. I say go down to PPE (or Sikky if possible) and get them done directly. Frankly, I don't know of any shops here in Vegas that I completely trust with the install. I know the install is tough, and with my mediocre knowledge of cars, I didn't want to take a chance.*

 

Yea i have the PPE header / Joe Z exhaust combo, and have never had a CEL, running on about 9 months now

 

Yeah , waiting for ppe header group lolz...

 

I can't believe those gains!!!! I think my biggest issue is coming up with the funds for one and then shelling out some more money to get them installed since its a very laborious procedure

 

My PPE headers should be here in a week or so..... Cannot wait

 

My CEL came on twice but I unplugged the battery and reset the ecu so far gone for now....

 

Why do I keep on seeing the PPE guys with cells

 

me and my buddy just got our sikky header today.. hope no cel for us.

 

^ keep us in the loop after the install with your opinions and comments please.

 

I've had the exhaust on for a year an a half and never have had a cel
