Ok, I ordered my RB header, and I am wondering 2 things:
1. Does it have a bung for the O2 sensor?
2. Do I need to leave the O2 sensor on?

Any help is most appreciated! And Scott, I have already searched!

 

Help?!?!?

 

i ordered the true dual and it has a hole for the o2 sensor other question have no clue!!

 

Bump, Daddy, Bump!

 

It's there to help the car use less gas, and with a rotary, that's always a good thing! Keep it.

 

Cool. Thanks! I will just replace the old one as I put in my new header!

 

Yes, it does have one. Just after where each pipe meets and just before the flange for the cat. They include a wire to extend the O2 sensor wire.

As for needing the O2, for good gas mileage yes, but all it does is minor corrections. At WOT the computer doesn't even pay attention to the O2 sensor reading.

So would it be in my best intrest to use it? If I did not, how would I plug the bung? Also, I failed to mention it is the streetable header/collector, if that really matters!

 

There's no advantage to not using it, so why wouldn't you?

 

Just askin! Thanks guys!
