Installed mine tonight. More pics can be found in my build thread.
The o2 wires are a bit tighter than stock and with the magnaflow downpipe I replaced out. The front o2 sensor is too tight to even clip the connector back in the bracket beside the rear connection.
*Let me be clear, I'm not displeased. I would suggest looking into the o2 bung locations though, especially the front bung. It would do much better a little further up the pipe.
This is the rear line stretching to reach:
This is a HORRIBLE picture of the front o2 connector dangling since it wont reach to snap back into bracket:
Bung placement. CJPP vs Magnaflow:
Lastly, this is the downstream o2. It gets very close to that heat shield. I recommend pushing down the heat shield for anyone who puts this in.
