The header i was considering buying was from Mazzuri Super. Their website is http://www.mazzurisuper.com/ and run about $850. Out of the others I looked, these appeared to be constructed much better. They were also helpful over the phone and email. see ya. Quote Link to comment Share on other sites More sharing options...

sakataj Posted December 8, 2008 Share Posted December 8, 2008 whats all the wireing for? did u EVEN read the posts i sent u? apprantally not cause RIGHT under 1st pic it says "This is actually where I have stopped for the night. It is late and I need an O2 sensor to replace the one before the cat because it is impossible to remove. I will call LMS tomorrow and get the details on how to wire it in, per LXOGOOD's recommendation because, to my knowledge, he is the only other member with a header installed on the GS300. I have been in communication with him for a couple months about this install and he said LMS handled everything. O2simulator.com does have a skimpy "guide" for an IS but, the diagram does not match what I see. I even had a fellow CL member "kurby" from the IS forums open his up for me and the connector was still different. Here is the link to the seeminghttp://us.lexusownersclub.com/forums/index.php?#ly wrong IS diagram. No connector on either of ours under the cover has four rows of wires. We both have three." essentially he is needing a new o2 sensor, buys a O2 simulator instead and these are the directions to wire it BUT he then realizes he has the wrong ones,he eventually gives you the right ones.....bout 3 pics down Quote Link to comment Share on other sites More sharing options...
