Is it worth getting shiny down pipes?

[Skippernick]

There is nothing wrong with  the originals, thats why yamaha put them on. The problem is that they rust which depends on how often the bike goes out in the shite during winter, i ride mine all year it has 18,000 miles on it and where pipes one and two, three and four join it has rusted in the v joints, if you maintain them they'll be fine. I asked this question to my dealer and they said keep the originals.
I can't afford new ones so repairing mine.
It is an 02 bike and there is no stainless steel involved in the exhaust system.
