Get some Bosch 13111 02 sensors.....long wire[no need for extensions] and they have a wider heat range so the possibility of getting codes is lessened..I have them and no codes....been on since last June. Make sure you have some good band clamps---NAPA has ones that alot of us use.

Its up to you what to do, either new sensors or extensions but youll also want to buy some band clamps. Theyll be better than whats supplied with most exhaust systems if they give you anything at all.

you only need 2 02 xtensions, but you'll need 2 02 sims for the downstream so you don't have that annoying code tripping the SES light

If you have something like ls1edit or hp tuners or a vinci tuner then you wont have to worry about the SES light. I might also recommend some poly motor mounts too, other wise you're either going to bang the y pipe, or adjust it so much that you cant drive over a cigarette butt.

On top of the O2 extensions, I'd say get some new GM Steel Header Gaskets, Stage 8 header bolts, TR-55 plugs, MSD wires; since you'll be in there anyway, might as well change the plugs/wires.

LS1speed.com (sponsor) has everything exhaust related on one page in the exhaust section. Easy to just bundle it up.

The gaskets that ship with PaceSetters, for example, are shitty. The locking bolts will keep the headers on nice and tight, which will save you the hassle of re-tightening them every so often. It's worth spending the extra money to avoid problems later down the road, and it's not that expensive compared to what you're about to drop.

The plugs and wires are good quality. You can skimp and get lower-end stuff, but it's up to you.

Of course, the band clamps at NAPA are a must, at least for me. I was scraping on speed bumps until I got them.

Will he still need the sims even though hes running a catted y-pipe?
