[urq] I see the middle muffler goes for 600 to $750 from Audi

857 253 409a.   I think mine will probably go in a few years.  Does it make any sense to buy it now from Audi (if even available).   A few years ago I looked a urq for sale where a shop probably had just made up the middle muffler section, probably for less money, but it looked to me like it was just an inch too long and the hangers looked like they were stretched a bit to much and it looked like a probable headache for the new owner to be.   Buying in advance means I can get it before it goes NLA  and maybe before Audi raised the price by another $100.  
I'm not worried about the rear muffler - there seem to be some good options there.
