MY2000, 110K. I am doing a piggie DP and Twin2 install shortly and was wondering about the secondary O2's. I have relocated bungs on my piggies. I have no idea when/if the O2s have ever been changed. My B2S1 Lambda O2 is bad so I am replacing both the front ones and planning on using those old ones as "plugs" for when I relocate the back ones.

Should I just go ahead and replace the back ones as well since I will have everything out and I can get the set from Va5t that are already lengthened? How hard is it to lengthen them yourself (I have read different info on this, some say not to soldering, others say not to crimp) if I don't replace the back ones, and/or how hard is it to replace the back ones once everything is back on if I decide not get new ones right now.

Opinions/suggestions

Thanks guys.

Search for "anti foulers" for your piggies. no need to relocate or plug o2 bung.

The new bungs are right off the rear cat, so I "should" be able to make the current O2 wires reach if I clip the wire tie on top of the tranny and unclip the wire from the firewall (from what I have read). I guess I am more wondering if I should just replace them since I will have everything out, and I have no clue the last time, if ever, they were replaced.
