LG header w/ out cats Question...
I just got my LG pro long tube headers. They have no catylitic converters and I noticed that there are two 02 sensor holes on the x-pipe and one on each header for a total of 4! 
The headers also came with two 02 extensions (one of which came broken and I have to send it back) and I didn't think these headers would use that many 02 sensors, especially since they don't have cats. And on to my next question......when I buy the 02 sims, (which I know I'll need) where do they go? 
I just want to have a good grasp on this before I start the project......Thanks in advance!!!

Ok, if you have a 2000 vette you will have to use the rear 02 sensors in the front. then use the old front sensors to plug up your rear unused 02 sensor holes just as a "dummy plug". Your rear 02 sims will plug into the connector where the rear 02 originally plugged in to.
The main mistake installers make is to hook up your 02 sensors to the wrong side. Just remember that which ever side the sensor comes from is the same side of the engine it has to go in. Drivers side 02 to drivers side of engine.
If you or your installer has any problems just call us and we will help you out. There should also be a detailed set of instructions in the box also. If not, I can email a set to you.
Thanks and you will enjoy them when you installation is complete.

So the sensors in the back won't be plugged into anything? And the 02 sims will be plugged into the outlet the rear sims would have been plugged into.....Correct? Thanks for the quick reply, I really appreciate it!
One other issue since I have your ears, when I purchased these headers, I also purchased a stage II rear diff. with 3:90 gears from you guys (really excited about it). I also bought the DTE hardened output shaft and gear (right side) and paid for the labor to have you guys replace the OEM right side with the Hardened one. Now Rick is the one I purchased all this stuff from and he isn't around anymore, so I'm worried about the status of this whole thing considering its been about 2 weeks since I ordered the rear differential. I understand it'll take a while to build and swap out the OEM to Hardened, but my car is up on a lift and I miss her something feirce.
Again, thanks for the quick reply about the headers. I'll call if I have any issues during the install, and tommorrow I'll call about the broke extension. I have had nothing but good experiences so far from LGM!!!

You are correct. The sensors in the back,if you don't run cats, will not be plugged into anything and the sims will do exactly like you said.
We have 3 other very qualified salesmen and one of them has taken your order over. They will take very good care of you (and if they mess up, please just call me directly)
Call me tomorrow and I will go over the whole order with you.
Thanks for the business.
