Just a small question. Why do you still need the o2 sensors in the header if you got an o2 simulator? Isn't the whole point of the o2 sim so that you can remove the o2 sensors without trowing a cel? Also, how is the power improvement? Big difference?
Edit: Ok, nevermind....lol I feel like a fool now. I see that you still have the o2 sensor in place pre-cat. The sim is post-cat(or at least where it used to be ). Makes sense

i just put the same header on my 02 gs300, but the "y" pipe was totally wrong. too short, not angled right and the o2 sensor hit the heat shield. did you experience this and if so what solution did you come up with? right now i have just the header on and the stock "y" pipe until i figure out a solution. also did you use the gaskets they gave you or replace them with the factory lexus gaskets? sorry about all the question, but i'm just kinda stuck.
