I will be in a similar position one day, as might a lot of folks.
The flexible pipe in question has an internal straight pipe secured at one end. Over time, they get a bit eaten away. on my car, it had become detached.
when the day comes that the pipe starts to fail, or before if I can get other jobs sorted beforehand, I will likely get a flexible section of hose like the stuff in the link, and have a pipe made.
I'd hazard a guess that a decent aftermarket exhaust shop could make one, or provide the bits.
Alternatively, I could get something made to dump to atmosphere
