O2 eliminating downpipes

[Black95TSIawd]

I plan on getting a dowpipe as soon as i can choose which one to order. I like the fact that O2 eliminating downpipes can dramatically decrease lag. I was wondering if there is an insert to put the O2 sensor or does this setup completely get rid of the sensor. Also, is it better to dump back into exhaust or outside? Thanks for any info!!

I Have a hahn race craft down pipe with the O2 elimiator. I love it, the O2 screw right in. But the only down side you will need to use a VR4 oil fittler instead of the Eclipse one. I think it's worth the money

the biggest gain to be had imo would be eliminating (or greatly reducing) creep. It must have a bung for the 02 sensor, otherwise your car will run like crap anytime you are not at wot. in/out the exhaust is your pref. Back in is legal, whereas dumping is not (of course, most of us are in violation of several automotive laws as it is) because of emissions and the noise (theoretically you could muffler the dump tube, but there isn't a whole lot of room in there).

I was looking at the 2.5in O2 eliminator downpipe from RNRracing. Do they have the sensor insert and are these downpipes good? I'm not too familiar with the products form this company.
