Maintenance/Upgrades during DP install?

I'm planning on getting my catless DP put on my N55 xdrive pretty soon here. Apparently, it's a massive pain in the ass on an xdrive and I'm guessing it will take my mechanic a nice chunk of the day to complete. Is there anything else I should consider doing while he's got it all torn apart for the downpipe?

It's not too terrible but did take me a while. Maybe check plugs and coils since you have to take apart some of the engine plastics to get to the o2 sensors

I was thinking maybe upgraded diverter valve or something? Not sure how many guys actually do that/if it's necessary for Stage 2. I did the plugs and coils just a few thousand miles ago, so I think I'm good on that!

Only upgrade the diverted valve if doing a bigger turbo and even then I would wait until you do the turbo to upgrade the DV

I would replace engine/transmission mount if it looks worn

if you have the funds and haven't done so already, might want to tackle the water pump and t-stat. you'll be moving the steering rack already and be in that general area. otherwise, there's not a ton that would be duplicate labor.
