SIKKY Headers x2 ISFs and x2 States (LOTS of PICS)

![Default](https://www.clublexus.com/forums/images/icons/icon1.gif)
Our quest for more HP... my buddy (obby) and I after owning turbo'd s2ks we decided that our F's needed a little bit more power so I contacted Portland Speed Industries up in Oregon and told them to expect us coming up from CA. The reason why we decided to make the drive up was because of their knowledge and past experience.
We both decided on Sikky headers after reading great reviews of the header making good power and checking youtube videos (always gotta check youtube
) We had PSI place the order with Sikky and two weeks later we both made the journey up to Oregon.
Once we were in Oregon our plan was to stay for 3 days to get the headers done, get in some tax-free shopping on be back on the road back to CA, however thats were it all turns ugly... What we didn't expect was both cars needed new o2 sensors since the OEM ones both strip out and no one had them in stock expect for sewell lexus. We had them overnight 4 sensors however they only sent two on one day and the other two the next day, extending our stay another extra 2 days. If your going to do headers on your car, do yourself a favor and order 2x OEM o2 sensors! Don't buy aftermarket!
Here are the pics:

In the end the car dyno'd 1HP shy of 400whp, when I had aftermarket o2 sensors in my car which actually kicked it into limp mode. I'm sure the car will actually put over 400whp with the right OEM o2 sensors now. I will dyno my car again this summer and will post results![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)
