Also, it's worth being prepared to purchase spare primary O2 (
upstream) sensors on hand -- I'm not saying you should definitely buy them in advance, but be prepared to have some extra $$$ on hand at need. The O2's can get damaged pretty easily in removing them from the OEM headers, and symptoms (e.g., wonky fuel trims or CEL's) may not even show up right away.
There is a generic Denso part #234-9036

See also here -- the primary O2's sensors:

Post-cat (downstream) ones can go bad too, but they're less of a concern (Denso part #234-4380

If you have any O2's fail on you after install, the above ones should work well, and be MUCH less expensive than buying from Nissan.
Keep in mind that the connectors may need to be re-spliced -- Nissan changed the connector for some reason on later MY's -- but you'd need to have splicing done anyway for the wire extenders that will need to be used with the LTH's.
Also, get heat shielding for those sensor wires -- like heat reflector wraps with zip ties or something.
