O2 sensors
Installing some long tubes and really in need of a slightly shorter o2 sensor.. Anyone know of a product like this? I just don't have enough clearance with it how it is, I need about a quarter inch less. Thanks for the help in advance.

what brand of long tubes are you running?? that will be a great help in helping you with the problem at hand! and 90% of the long tube installs take out the front O2' sensor's via tuning the car while relocating the rears to the front via wire harness

I'm in the process of installing the same headers on my '04 Z06 and the driver side O2 sensor is definitely close on clearance. I don't know of any shorter O2 sensors out there.. to get clearance on headers the typical fix is to have a shop relocate the bung to where you'll have clearance.
If you purchased from Jon at Huron Speed (Superman09 on here) you should contact him directly and let him know what issues you're having.. he'll help you out!!
Good luck!

Are these the latest XS power headers?
I have an older set. But I bought new AC Delco sensors. It's possible the latest design sensor is shorter. It is a different design.
Here is a comparison, not sure if you can tell from the pic.
Here are the headers to compare to yours.
I don't recall any clearance issue for the front sensors. Or are you talking about the rears? If so, sometimes you need to cut holes in the tunnel plate for clearance. I tuned my rears out and eliminated them.

The input from the front O2 sensors is NOT tuned out!
The rear O2s sensors are placed into the front O2s wiring harness (via adapter harness) and front bungs for faster heater element warm up times. This eliminates lazy O2 heater element codes on your DIC caused by the sensors being further downstream in long tube headers.
The front O2s affect engine performance and help scheduling of fuel and affect A/F ratios. do not tune these out.
Then the input from the rear O2s is tuned out. The rear O2s only give codes related to the catalytic converters health/effectiveness. They can be tuned out because they do not affect engine parameters such as A/F ratios.
Just a point of clarification as this is confusing to some.
I have read that the later model (04) C5 O2 sensors are improved and that the front O2s can be run in the front position with no O2 heater element codes, even used in long tubes.

These are on the latest xs headers. I took it to an exhaust shop and they put it in the location they thought was best but there still isn't room. They had to relocate the drivers side to the very front of the x pipe but I still have issues. I have no idea where else I could put the o2 bung

With these headers the o2's were supposed to plug back in right as they came out, fronts to the from, rears to the rear. Unfortunately I didn't have clearance for the drivers side so I plugged it and took it to an exhaust shop who welded in another bung to fit, unfortunately there still isn't room.
