Yeah yeah yeah... your all right!
I have the hoses of the filter extermly close to my exhaust and never had a problem with them.
Though I will replace the hoses by solid steel lines when I do the new 261 - just for peace of mind.
Probably the hoses would work for an other 10 years close to the exhaust pipes but with the steel lines I just have a good feeling.
So both of you are right. Hoses may work and never give any trouble, steel lines are even better.
