Subframe Drop on 535XI Necessary?

[10535XI]

Have a handful of repairs I need to do on my 2010 535XI Wagon. N54 engine. Is it necessary to drop the subframe to replace the turbo inlets/outlets with silicone upgrades and adding catted DP’s?

Repairs/upgrades needed:
Valve Cover Gasket
Fuel Injector Test
Oil Housing Gasket
Oil Pan Gasket
Upper Radiator Hose
Turbo Inlet + Outlet
Engine Mounts
Oil Catch Can

Trying to get everything done all at once since I’ll have to take some much apart just for the oil filter housing gasket. Subframe drop with the XI AWD seems like it might be an extra pain compared to RWD cars.
