Crome by all means, as it sounds better and looks better too. When i first put on a new set of cromed Jota muflers on my former RGS many moons ago, it had become rather late in the evening, say like 04:30 am, I went straight to a Laverda friends house, turned off the bike when getting nearer his house, and dragged the bike up to his front door, put a glove in his letterbox to make sure there was free entrance from outside to inside, and started the bike and became heavy on the gas. The response from inside the house was: "AAARRRGGGhhh, someone is stealing our Laverda's, hurry! Where are my underpants?" etc..... Later on followed by some beers. I think that my idea was a very mature and well thought out idea, with some vice social aspects (the beer part). Apart from the fact, that I did not give it too much thought, other than "Hmmm, let's make someone aware that I now have a set of Jota cans on my bike" More like a natural reflex, so to speak
So crome works for me
