O2 wire extensions and rear O2 bung extensions with long tubes ??? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

What length O2 wire Sensor Extensions are required when installing new long tube headers , is the "Trapezoid 4-Position 12" HIGH TEMPERATURE" the best for the front sensors ?
What about the rears, are they required there too ??

I going with a cat delete set up, will the O2 sensor bung extensions help to prevent throwing a code ? Will any of these work http://bigdaddiesgarage.com/

I'm guess in the rears might as well just be tuned out as I'll need a tune when I finish installing headers and a cam

Thanks !!

I've been told that they work by people here, and I received my set about a week ago. I went with the angled ones instead of the Mini-Cat ones, so we'll see once I install my Catless Pipes.

You do not need extensions for the rear. You WILL throw a code with long tube headers and no cats unless you get a tune. You are leaving approx. 20-25hp on the table by NOT getting a tune. Therefore, I highly recommend you get the car tuned.
ALSO, if you do get the car tuned, the rear O2 sensors get completely deactivated to the point that you don't even need to install them in your catless mids. You can simply install bung plugs instead. This is how I roll on mine...

holy shit, just checked the site and $50 is ridiculous.

I've done this on my old rsx-s, on my ex's prelude, and know plenty of people that have done it. but you dont need a specific overpriced part. they have it at autozone for like $8.
