How to "split" and flatten a multisurfaces model (motorbike exhaust)

[Fabz]

Hey People, I have made a 2stroke motorbike exhaust from lofted surfaces and i'd like to flatten each segment of this exhaust in order to laser cut each little pieces. Can someone help me to do so because i'm proper stuck i spent 5 days nonstop on it to find a way arround impossible!!! I know the option sheet metal is possible but again it can't be made with multi "conical"ish rings. If someone thing he can help me then i'll share the folder in order to find a solution. For now i attach just a screen shot of it. Thank you all.

It would probably be better to ask this question in the relavent software forum.
