Actually, I checked what exactly Ista+ says how to remove downpipes from 335xi and it's about like this, no subframes no nothing, just a lot of pre-work:

Removing and installing/replace catalytic converter for cylinders 1-3 (N54, N54T

- Remove underbody protection
- Remove exhaust system
- Remove cable clip on side of transmission for control sensor/monitoring sensor


- Remove right output shaft

Remove track rod end from swivel bearing.
Remove guide joint from swivel bearing.
Remove wishbone from swivel bearing only
Remove anti-roll bar link from spring strut
Press output shaft out of wheel hub and tie up


- Remove right bearing support
- Remove oxygen sensors

- remove both downpipes

So is this wrong method and you have tried this way and its not working?

I have done it the subframe dropping way several items and it is far easier than what you describe here. No suspension disassembly no removing driveshafts, etc. The exhaust you just unbolt from the back end of the DP's and let it hang. You can remove rear muffler hangers if you want to get a little more clearance. You only unbolt the subframe, not remove it, and let it hang down a few inches for some clearance. Make sure the motor is supported obviously. I prefer using the hoist that sits across the upper fenders (cheap from Harbor Freight here in the US) but you can support it on blocks underneath if you are careful. Done it both ways, the hoist is easier, more room under the car.
