My new to me 1974 R90/6 has what looks like the original exhaust system. (50,000 miles) The mufflers look great, but the exhaust pipes look somewhat worn.
-If I replace them with stock ones can I keep them from turning blue? I replaced the exhaust pipes on my 1973 Triumph and my mechanic sprayed the inside of them with some kind of coating and they did not turn blue.
-What about stanless steal? Will they look the same as my mufflers or will they have a different finish?
-Do SS pipes turn blue.
-Are blue pipes just part of being cool and I will be considered a rookie airhead if I don't have blue pipes and I will have to live in shame?
