I would look for them between the catalytic converters. (The following is a photo of 2014 OEM config)

Secondary O2 sensors are after the first cat, so pretty much right in front of your feet.

apparently not on the ACR, they are on the bend of the tailpipe ???

No, the sensors are definitely NOT in the bend of the tailpipe on the ACR. Look at AZTVR's photo above.

You may be thinking about a post or photo of a Bellanger configuration.

On the Belanger system, the downstream O2's are not in the tail pipe either unless Lou changed the design over the last two years.

I was recalling post #15 in a thread from earlier this week, and the thread also had a photo to show where the bungs should be now. https://driveviper.com/forums/thread...l=1#post421851

Rear bung position now

yes i agree, at first when i got my Belanger, the secondary was by the tip, i was just querying this, but since installing the Belangers, the primary bung has been moved down from the tube, where the older ones used to be, down to the collector, so my primary O2 sensors are now 12" too short

I found O2 sensor extensions for my Gen2 years ago when I moved the upstream O2 sensor to the collector in those Belanger headers. I don't know if the supplier makes an extension for the GenV but worth a look. Caspers Electronics is the manufacturer. Summit sells them maybe they have one for the GenV. https://www.summitracing.com/search/...s?fr=part-type

Thanks Tony

I'd also call Lou Belanger too...he must know a source. Dan Lesser, Dan Craigan, JonB, etc. I'm sure they've all run into similar situations requiring the need for extensions.

Also it appears Amazon has them.... https://www.amazon.com/2014-2017-Che...3981073&sr=8-3

Thanks Tony,

ARH headers on my Gen 4 required extensions but they were provided by ARH. The plugs and sensors are different on a Gen 5 though so the Gen 4 extensions wouldn't work.

By the way, if you are running the Mopar Controller you don't need the rear sensors just install a threaded plug in the bung.
