Just got the car back and they won't cover it - the warranty guy said he could show me other cars of similar age with exhausts in the same condition. The docket says "Standard signs of corrosion due to vapour / liquid coming out of exhaust. Not warranty". Oh well, it's what I was expecting - a replacement would be pretty pointless as they'll be the same in 6 months anyway.
The campaign by the way was "20Z6". I thought there would be more detail on the paperwork, but that's all it says. There's nothing on the internet about it at the moment.
So, as they really are quite tatty, I'm going to replace the tips with stainless steel ones. I've looked here, and although it's for S4, the two pictures don't seem to be for the same exhaust system - looks like twin x 1, single x 2 but not quad:

Edit: ok I think this is B8 (It said "Europa Year 2016" so thought that meant B9!)
Any ideas if I want 60mm, 80mm or something else? (I know I could measure it but I don't know whether this refers to internal / external / pipe / trim diameters).
Also, anyone got any good suppliers or links to suggestions? I want to get as close to stock as possible.
I suspect there may be a few of us needing to do the same over time, so I'll happily be the guinea pig if you guys can help me source them
