In need of Star developer mode
I'm looking for someone in the CT/NY area that has one that's willing to help me. I recently installed long tube headers without cats and I need to turn off the rear O2 sensor codes.
Thanks in advance

install these on your rear o2 sensors and you'll be fine: http://www.ebay.com/itm/O2-oxygen-sensor-test-pipe-extension-extender-adapter-spacer-M18-X-1-5-2-Bung-/161119594890?pt=Race_Car_Parts&hash=item258379e98a&vxp=mtr

Resurrecting this thread because I'm on the same boat. Does anyone know of the proper length o2 sensor spacer to use on a C55? Also, after installing the spacer, would I need to have the code cleared so it won't return or will it go away on its own?

Just as future reference for anyone else who drives a C55 and removed the secondary cats - the 1" spacers I ordered didn't work. They had a reduced tip and installed fine, but the CEL was still on after weeks of driving; clearing the code would work for a few days then then return. I then tried the ones below and installed as follows: screw them in fully, then back them out 1.5 to 2 full turns and tighten the locking nut. Two and a half days of normal driving later and the CEL cleared itself.
