I like chrome pipes, yet dislike discolouration, it looks to my untrained eye that it is limited to the actual headers, i.e. the part just aft the engine, but the actual pipes after the initial bend remain virgin. A bit of reminder that a real machine sits up front is OK, much of the pipe sullied isn't.
I'm assuming the lovely three eared knockers are also available as is the equally lovely wood Moto Lita?
Re the discolouration - it is pretty much confined to the headers. From the flexible joint backwards it's not too difficult to keep everything shiny.
3 ear spinners are available from Morgan and others such as MWS (who supply the wheels):

Have great fun on your test drive and enjoy speccing your new pride & joy
